Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a temperature sensor is positioned near the battery to measure temperature, then measurement precision is improved, but the relative positioning may change leading to inaccurate readings

Engineering Contradiction:

Improvetemperature measurement accuracyVSAvoidmeasurement reliability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The resilient component is positioned between the temperature sensor and battery to preemptively absorb external forces and maintain consistent thermal contact. This cushioning approach ensures that the sensor remains in reliable thermal proximity to the battery even when subjected to device handling, dropping, or structural changes, thereby resolving the contradiction between measurement precision and reliability.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Measurement precision

If the temperature sensor is directly attached to the battery, then measurement accuracy is improved, but the device becomes more vulnerable to damage from external forces

Engineering Contradiction:

Improvetemperature reading accuracyVSAvoiddamage from external forces

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The resilient component serves as a protective cushion between the temperature sensor and battery, absorbing external forces before they can damage the sensor or disrupt its thermal contact with the battery. This allows the sensor to remain directly attached for accurate measurements while being protected from harmful external impacts.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The resilient component changes its physical parameters (compression, elasticity) in response to external forces, maintaining consistent thermal contact between the sensor and battery while absorbing impact energy. This dynamic parameter adjustment protects the system from damage while preserving measurement accuracy.

Inventive Principle:

Principle #35Parameter changes

3Object-affected harmful factors

If a resilient component is introduced between the battery support and battery, then protection from external forces is improved, but device complexity increases

Engineering Contradiction:

Improveprotection from external forcesVSAvoidstructural complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The resilient component performs multiple functions simultaneously: it protects the temperature sensor from damage, maintains consistent thermal contact for accurate measurements, and provides mechanical cushioning against external forces. By consolidating these functions into a single component, the design protects against harmful factors without proportionally increasing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The resilient component acts as an intermediary element between the battery support and battery assembly, mediating the transmission of forces while maintaining thermal contact. This single intermediary component resolves multiple issues (protection, thermal contact, stability) without requiring multiple separate mechanisms, thereby limiting the increase in device complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)
