Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle batteries face challenges in maintaining effective temperature control, particularly when the temperature control mechanism is damaged due to road irregularities, leading to inadequate cooling of battery cells.
Innovation Solution
The design incorporates a temperature control mechanism with a flow path and protrusions/recesses on its surfaces, ensuring efficient heat transfer and maintaining contact without gaps, even when deformed, to secure the flow path and enhance cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the temperature control mechanism is disposed in the vicinity of the bottom surface of the vehicle, then the cooling efficiency is improved, but the mechanism is vulnerable to damage from road irregularities
Solution Approach 1:
The patent applies beforehand cushioning by providing a cushioning member between the temperature control mechanism and the battery module. This cushioning member absorbs mechanical shocks from road irregularities before they can damage the temperature control mechanism, while still allowing the mechanism to maintain effective thermal contact with the battery module for efficient cooling
2Reliability
If the temperature control mechanism deforms due to external impact, then the structural integrity is compromised, but the flow path must remain secure for continuous cooling
Solution Approach 1:
The patent applies dynamics by making the temperature control mechanism flexible rather than rigid. The mechanism can deform elastically under external impact to absorb shock energy, then recover its original shape. This dynamic behavior allows the mechanism to maintain structural integrity while ensuring the flow path remains secure and continuous cooling operation is sustained even after deformation
3Reliability
If protrusions or recesses are added to the flow path walls, then the flow path security is improved during deformation, but the manufacturing complexity increases
Solution Approach 1:
The patent applies local quality by adding protrusions or recesses only at specific critical locations on the flow path walls where deformation would most likely compromise flow path security. This localized modification provides enhanced flow path security during deformation while minimizing the overall manufacturing complexity compared to redesigning the entire temperature control mechanism

AI summary
An in-vehicle battery includes a battery module, and a temperature control mechanism. Inside the battery module, battery cells are disposed. The temperature control mechanism is located in a vicinity of the battery module and configured to cool the battery module. A flow path through which a cooling fluid passes is provided inside the temperature control mechanism. A recess or a protrusion is provided on a surface on a battery module side among wall surfaces forming the flow path. A surface of the battery module and a surface of the temperature control mechanism facing each other each have a planar shape.
