Solution Overview
Problem
Existing battery assemblies suffer from impaired efficiency and overheating due to inadequate heat dissipation, as the thermal conductivities of retaining components and air are low, leading to inefficient heat dissipation.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If air circulation is used for heat dissipation, then the structure is simple, but the thermal conductivity is low leading to overheating
Solution Approach 1:
The patent introduces a heat dissipating means as an intermediary component between adjacent cells. This heat dissipating means comprises multiple independent spacer components made of flexible material with thermal conductivity greater than air, which act as thermal mediators to facilitate heat transfer from the cells to the surrounding environment, resolving the contradiction between structural simplicity and effective heat dissipation.
Solution Approach 2:
The heat dissipating means uses composite material construction with flexible material having higher thermal conductivity than air. The spacer components are made of flexible material that combines both mechanical flexibility for cell accommodation and thermal conductivity for effective heat dissipation, creating a composite solution that addresses both structural and thermal requirements.
2Reliability
If retaining components with low thermal conductivity are used, then the cell is securely fixed, but heat dissipation efficiency is impaired
Solution Approach 1:
The heat dissipating means acts as a thermal intermediary component positioned between adjacent cells. The spacer components with higher thermal conductivity than air serve as mediators that conduct heat away from the cells while the retaining components maintain secure fixation, thus resolving the contradiction between reliable cell fixation and efficient heat dissipation.
3Device complexity
If gaps between cells are left empty, then the assembly is simple, but heat dissipation is insufficient
Solution Approach 1:
The heat dissipating means comprising multiple independent spacer components is introduced as an intermediary element in the gaps between adjacent cells. These spacer components facilitate heat transfer from the cells to the surrounding environment, resolving the contradiction between simple assembly structure and insufficient heat dissipation.
