Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the thermal management component uses a conventional rigid structure, then the manufacturing process is simple, but the manufacturing precision is poor due to manufacturing tolerances

Engineering Contradiction:

Improveassembly precision between thermal management component and battery cellsVSAvoidstructural complexity of thermal management component

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The bent wall is designed as a deformable structure that can dynamically adjust its shape during compression. When the thermal management component is compressed along the first direction, the bent wall deforms to absorb manufacturing tolerances, enabling the component to adapt to different assembly requirements and achieve precise alignment with battery cells.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The component utilizes changes in geometric parameters during assembly. The bent wall's curvature and position change when compressed, allowing the component to transition from a state with manufacturing tolerances to a state with precise dimensional control, thereby improving assembly precision.

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If the thermal management component is compressed to absorb manufacturing tolerances, then the assembly precision improves, but the connection between bent wall and straight wall may rupture

Engineering Contradiction:

Improvesize control of thermal management componentVSAvoidstructural strength at connection between bent wall and straight wall

Core Design Contradiction:

Manufacturing precisionVSStrength

Solution Approach 1:

The bent wall is designed with increased thickness specifically at the connection regions with the straight walls, creating a cushioning effect that prevents rupture during compression. This preemptive design ensures that the connection points can withstand the compressive forces applied to absorb manufacturing tolerances.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The bent wall exhibits non-uniform thickness distribution, with increased thickness at critical connection points and reduced thickness in other areas. This local quality enhancement provides targeted strength where needed (at connections) while maintaining overall deformability for tolerance absorption.

Inventive Principle:

Principle #3Local quality

3Strength

If the bent wall thickness is increased to prevent rupture during compression, then the structural strength improves, but the manufacturing difficulty increases

Engineering Contradiction:

Improvestrength of bent wall to prevent ruptureVSAvoiddifficulty of manufacturing thermal management component

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The bent wall employs local quality enhancement by increasing thickness only at specific critical points (connection regions with straight walls) rather than uniformly throughout. This targeted approach provides the necessary strength to prevent rupture during compression while minimizing the overall material usage and manufacturing complexity.

Inventive Principle:

Principle #3Local quality
