Battery Pack Fixing Protrusion Design for Slimmer Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery packs face challenges in achieving a slimmer structure while stably fixing the battery module due to the need for additional space for coupling structures like bolts and nuts, which limits the pack case size and complicates assembly.
Innovation Solution
A battery pack design featuring a battery module with insert holes and a pack case with deformable fixing protrusions that permanently deform to securely fit into the holes, eliminating the need for additional coupling structures and allowing a slimmer form factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional coupling structures with bolts and nuts are used to fix the battery module, then the battery module can be securely fixed, but additional coupling space is required which limits the pack case size and prevents a slimmer structure
Solution Approach 1:
The fixing protrusion integrates both the coupling function and the fixing function into a single component. The protrusion directly engages with the battery module's mounting features, eliminating the need for separate bolts and nuts, thereby reducing the required coupling space and enabling a slimmer pack case design while maintaining secure fixation
Solution Approach 2:
The invention extracts and eliminates the unnecessary coupling elements (bolts and nuts) from the fixing system, retaining only the essential fixing protrusion that directly secures the battery module. This reduction in components removes the need for additional coupling space and enables a more compact pack case structure
2Stability of the object's composition
If conventional coupling structures with bolts and nuts are used to fix the battery module, then the battery module can be securely fixed, but the assembly process becomes more complex
Solution Approach 1:
The fixing protrusion combines multiple functions (coupling, fixing, and positioning) into a single integrated component, eliminating the need for separate bolts, nuts, and associated assembly steps. This simplification reduces device complexity while maintaining secure fixation of the battery module
Solution Approach 2:
The invention removes the complex coupling mechanisms (bolts and nuts) from the system, retaining only the essential fixing protrusion that achieves secure fixation through direct engagement. This extraction of unnecessary components significantly simplifies the overall structure and assembly process
