- • Yesterday you compared three approaches; today you go deep on one specific design.
- • You will evaluate it against the function it must restore, find a weakness, and propose a fix.
- • This engineering-analysis format mirrors the design-process content on the 072130 WebXam.
- • Your analysis notes become the evidence base for tomorrow's written design critique.
- • Design criteria specify what the intervention must do; constraints specify what it cannot do.
- • A strength addresses the primary design criterion; a weakness violates a secondary criterion.
- • Any proposed improvement shifts the trade-off space and may worsen another constraint.

The deck carries the prior idea forward, lets you inspect an analogy, maps the rule to biology, and ends with the same evidence decision and exit ticket used on this page.
Generated from this lesson's canonical data with a red-team citation check.
No single replacement strategy wins; the best choice depends on which limitations are most acceptable for a specific patient.
Every engineering design is a set of trade-offs; the best design minimizes the most critical failure mode for the specific patient.
A bridge prototype is tested against a load limit, cost limit, and user need before revision.
- Which requirement is a criterion?
- Which limit is a constraint?
- What test result should trigger a redesign?
A design improves when evidence is compared with explicit criteria and constraints.
Biomedical designs also require , ethics, and biological validation beyond a physical prototype test.
- • Bridge requirements map to design criteria.
- • Load results map to E1-E3.
- • Revision maps to the next evidence-based iteration.
Driving question: Analyze an emerging-intervention design and judge how well it restores the lost function.
What you already know: No single replacement strategy wins; the best choice depends on which limitations are most acceptable for a specific patient.
New idea: Every engineering design is a set of trade-offs; the best design minimizes the most critical failure mode for the specific patient.
Visual or model: F1. F1. A lesson illustration or teaching diagram for Design analysis. Use it with E1-E3; it is a model or context image, not experimental or patient data. What to notice: Trace the labeled testing, treatment, or biological process and identify where evidence limits the decision.
- Observe or measure the relevant feature in Design analysis.
- Organize the observation with a stable evidence ID.
- Apply this rule: A design improves when evidence is compared with explicit criteria and constraints.
- Choose the option the evidence supports and state the limit of the conclusion.
Real biomedical example: Analyze an emerging-intervention design and judge how well it restores the lost function.
What the evidence supports: E1-E3 and F1 support the daily take-home when the response meets the stated success criteria.
What it cannot prove: The package does not support claims beyond this lesson's or any real patient diagnosis.
Use it now: Choose one decision option. Cite E1 and E3, then explain how the rule connects the evidence to your choice.
Go further, optional: The source links below are optional enrichment. Every fact required for today's local evidence decision appears in this lesson package.
Design criteria specify what the intervention must do; constraints specify what it cannot do.
Limit: E1 supplies context or an observation; it does not by itself establish the explanation.
Every engineering design is a set of trade-offs; the best design minimizes the most critical failure mode for the specific patient.
Limit: E2 is a teaching statement or comparison and must be checked against the task evidence.
You'll be able to evaluate a design against function criteria.
Limit: E3 supports only the result or product criterion named here; it cannot justify a broader clinical or causal claim.
PLTW-GEND-2026-12-15 · Simulated classroom evidence scenario
Your role: medical interventions team member
Decision: Your team must decide what the evidence from Design analysis supports before submitting the notebook record named on the lesson page.
- • Keep the current design.
- • Revise the feature that misses a criterion.
- • Run one more fair test before choosing.
Response: State one choice, cite at least two evidence IDs, explain the rule that connects them, and add one limitation. Submit it as the notebook record.
Claim ceiling: The supplied lesson evidence can support an observation, pattern, classroom mechanism, or next-step decision about Design analysis. It cannot by itself prove causation, establish a real clinical diagnosis, or justify action outside this classroom task.
Reason for review: Your team must decide what the evidence from Design analysis supports before submitting the notebook record named on the lesson page.
Context: Analyze an emerging-intervention design and judge how well it restores the lost function.
- • T1: Open the assigned design case in the PLTW course shell and identify the function it must restore.
- • T2: Evaluate how well the design meets the patient's need against stated criteria.
- • T3: Identify one strength and one weakness in the design.
- • T4: Propose one improvement and explain the trade-off it introduces.
- • T5: Submit your design-analysis notes as the day's evidence.
- • E1: Design criteria specify what the intervention must do; constraints specify what it cannot do.
- • E2: Every engineering design is a set of trade-offs; the best design minimizes the most critical failure mode for the specific patient.
- • E3: You'll be able to evaluate a design against function criteria.
Measurements: No patient measurement is supplied unless it appears explicitly in E1-E3 or F1. Do not invent a value.
Figure finding: Teaching diagram for Design analysis. Trace the labeled testing, treatment, or biological process and identify where evidence limits the decision. This is a teaching model, not patient or experimental data.
Uncertainty: This is a composite classroom scenario. Missing history, measurements, or confirmation tests remain unknown and limit the conclusion.
- • The solution must address the stated need in Design analysis.
- • The decision must be supported by E1-E3.
- • The final product must make the success criteria visible.
- • Complete the work inside the 80-minute block.
- • Use only supplied or teacher-approved materials and evidence.
- • Do not trade , accessibility, or privacy for speed.
- • and evidence quality: must pass before scoring other criteria.
- • User need and effectiveness: highest scored criterion.
- • Time, cost, and ease of use: compare only after and effectiveness pass.
Test evidence: For each option, record the E1-E3 result that supports or fails each criterion. Do not assign a score without a named observation.

- Criterion met or missed

Case: a bionic hand for a patient who lost a hand below the wrist.
Function it must restore: grip and basic object handling so the patient can hold a cup and a phone.
Criteria evaluation: The design must (1) close and open on the patient's intent, (2) grip firmly enough to hold a full cup, and (3) be light enough to wear all day. It meets criteria 1 and 3: it reads muscle signals from the forearm and weighs about 400 grams. It partly meets criterion 2: it grips a cup but slips on smooth glass.
Strength: it responds to the patient's own muscle signals, so control feels natural and needs little training (case data: 90 percent of intended grips succeeded).
Weakness: it gives no sense of touch, so the patient must watch the hand to judge grip force, which slows tasks and causes drops on slick objects.
Proposed improvement: add pressure sensors in the fingertips that buzz the forearm when grip is firm.
Trade-off: the sensors and feedback motor add weight and drain the battery faster, so all-day wear (criterion 3) gets harder.
(Tip: tie every strength and weakness to a specific criterion, not to a general 'it works well' claim.)
This model shows the level of evidence and organization needed to complete: Analyze one assigned emerging-intervention design against the function it must restore, naming a strength, a weakness, and one improvement with its trade-off.
- Date and label the entry.
- Record the procedure, observation, or design decision clearly.
- End with what the evidence means and the next step.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
Also due today: turn it in on the class site under today's design-analysis assignment.
