Battery Module Fixing Jig With Controlled Surface Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery holders for large vehicles require manual assembly, leading to low work efficiency and increased costs, and do not effectively control surface pressure during fixation, which can cause damage, noise, and overheating issues.
Innovation Solution
A fixing jig with a pair of body units, a pressurizing member, and a control unit that controls surface pressure through a rotatable pressurizing member and air pressure application, allowing precise fixation of battery modules to vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual assembly of battery holder components is used, then assembly flexibility is maintained, but work efficiency decreases and production cost increases
Solution Approach 1:
The patent combines multiple battery holder components (support piece, vertical pieces, side support piece) into a single integrated jig structure that performs alignment and assembly functions simultaneously. The body units with insertion grooves and pressurizing portions are merged into one device that guides multiple components into proper positions automatically, eliminating the need for manual alignment of numerous bolt holes and reducing assembly time while maintaining flexibility through the modular jig design
Solution Approach 2:
The fixing jig acts as an intermediary device between the battery holder components and the assembly process. The jig's body units with insertion grooves serve as mediators that guide the components into correct positions, while the pressurizing members mediate the joining force application. This intermediary tool enables efficient assembly without requiring complex manual manipulation or specialized equipment
2Strength
If high surface pressure is applied during battery module fixation, then fixation strength increases, but product appearance may be damaged and internal gaps may cause noise or overheating
Solution Approach 1:
The patent applies local quality by designing pressurizing portions that contact only specific local areas of the battery module assembly. The pressurizing members are positioned to apply force at predetermined locations through the body units, ensuring that high pressure is concentrated where structurally necessary for fixation strength while leaving other areas untouched to prevent appearance damage and avoid creating internal gaps that would cause noise or overheating
Solution Approach 2:
The fixing jig enables parameter changes by allowing controlled adjustment of surface pressure during the fixation process. The pressurizing members can apply varying degrees of pressure based on the specific requirements of different battery module assemblies, optimizing the balance between achieving sufficient fixation strength and preventing harmful effects such as product damage, internal gaps, noise, and overheating

AI summary
Provided is a fixing jig capable of controlling a surface pressure for pressurizing a battery module assembly when fixing the battery module assembly to an electric vehicle, which includes: a pair of body units facing each other each having one end branched into a supporting portion and a pressurizing portion formed therebetween with an insertion groove into which a part of the electric vehicle is inserted; a pressurizing member rotatably installed inside the pressurizing portion to pressurize the battery module assembly by controlling the surface pressure while selectively and partially protruding outward from the pressurizing portion; and a control unit provided on one side of the body unit to control a rotating degree of the pressurizing member to control a protruding degree of the pressurizing member outward from the pressurizing portion. Thus, a noise or overheating of the battery module assembly is prevented.
