Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery modules face challenges in simultaneously providing sufficient strength and efficient heat dissipation, leading to potential malfunction due to excessive temperature and structural weakness.
Innovation Solution
The battery module incorporates barriers with a base and protrusions made of insulation materials, such as ceramic or plastic, which are strategically arranged to support unit batteries and facilitate airflow for effective heat dissipation while preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If barriers are made with sufficient strength to maintain unit battery shape, then structural strength is improved, but manufacturing cost increases and cooling passage design is restricted
Solution Approach 1:
The barrier is segmented into a base portion and multiple protrusions, where the base provides structural strength and the protrusions provide cooling surface area and airflow channels. This segmentation allows each part to be optimized for its specific function without compromising the other.
Solution Approach 2:
The barrier incorporates a porous portion with through-holes that allow cooling air to pass through. This porous structure provides efficient cooling passages while maintaining the barrier's structural integrity and strength.
2Temperature
If barriers are formed with high cooling efficiency, then heat dissipation is improved, but structural strength decreases
Solution Approach 1:
The barrier is divided into a base portion for structural support and protrusions for heat dissipation. The protrusions extend into the cooling air flow path, increasing surface area for heat transfer without compromising the base's structural strength.
Solution Approach 2:
The porous portion with through-holes enables efficient air flow through the barrier, enhancing convective heat transfer from the unit batteries while maintaining structural integrity through the base and protrusion design.
3Reliability
If separate insulation members are used to prevent short circuit, then insulation performance is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The barrier combines multiple functions into a single component: structural support (base), heat dissipation (protrusions with cooling passages), and electrical insulation (insulation material). This eliminates the need for separate insulation members and reduces overall device complexity.
Solution Approach 2:
The barrier serves multiple purposes simultaneously: it maintains unit battery shape, dissipates heat through protrusions and porous passages, and prevents short circuits through insulation material. This multi-functionality reduces the total number of components needed in the battery module.

AI summary
A battery module includes a plurality of unit batteries disposed apart at intervals and a plurality of barriers interposed between the unit batteries. Each of the barriers includes a base supported on the unit battery and a plurality of protrusions extending from the base and contacting the unit battery. The protrusions are formed of an insulation material. In addition, the protrusions may be fixed onto the base in a staggered arrangement along columns and rows so that a certain angular arrangement between the alignment of protrusions is achieved, thereby maximizing cooling efficiency.
