Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional housing design is used for temperature measurement device, then the device structure is simple, but the high-temperature resistance is poor and integration is low

Engineering Contradiction:
Improvehigh-temperature resistanceVSAvoidhousing structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The housing is designed to serve multiple functions: it protects internal components, acts as a heat dissipation channel, and functions as electrodes for charging the battery unit. This multi-functionality resolves the contradiction by improving high-temperature resistance through active heat management while integrating charging functionality into the housing structure itself, avoiding additional complex components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The housing is divided into at least two parts that can respectively act as positive and negative electrodes. This segmentation allows each part to have specialized functions while working together as a unified system, improving both high-temperature resistance through distributed heat dissipation and integration by embedding charging functionality within the housing segments.

Inventive Principle:
Principle #1Segmentation

2Reliability

If traditional circuit board is used in high-temperature environment, then the device structure is simple, but the circuit board cannot withstand high temperatures

Engineering Contradiction:
Improvecircuit board high-temperature resistanceVSAvoidcircuit board structure complexity
Core Design Contradiction:

Solution Approach 1:

The housing acts as an intermediary heat dissipation channel between the high-temperature environment and the circuit board. By connecting the housing parts that serve as electrodes with the circuit board, heat is transferred away from the circuit board through the housing structure, protecting it from high temperatures while maintaining a relatively simple overall device structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If housing only serves as protection, then the device structure is simple, but the integration is low and high-temperature resistance is poor

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The housing is designed to serve multiple functions: it protects internal components, acts as a heat dissipation channel, and functions as electrodes for charging the battery unit. This multi-functionality resolves the contradiction by improving high-temperature resistance through active heat management while integrating charging functionality into the housing structure itself, avoiding additional complex components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The protective housing structure is merged with the heat dissipation system and the charging electrode system. By combining these functions into a single integrated housing design, the device achieves high integration without requiring separate components for protection, heat dissipation, and charging, thus improving reliability while avoiding excessive complexity.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If heat dissipation channel is created by connecting housing parts with circuit board, then the high-temperature resistance is improved, but the device structure becomes more complex

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The housing structure serves as both the protective enclosure and the heat dissipation channel. By making the housing itself the heat dissipation pathway rather than adding separate heat dissipation components, the device achieves effective thermal management while maintaining structural simplicity. The same housing parts that provide mechanical protection also conduct heat away from sensitive components.

Inventive Principle:
Principle #6Universality (Multi-functionality)
