Insulation Frame Pressing Portion for Battery Rattle Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric storage apparatuses fail to effectively suppress rattling of electric storage devices in a direction parallel to the main plate portion of the insulation frame, which can lead to positional inaccuracies and heat conduction issues.
Innovation Solution
The electric storage apparatus incorporates an insulation frame with a main plate portion, a first flange portion featuring a projecting pressing portion, and a second flange portion with a support portion, where the pressing portion is in contact with the electric storage device to prevent lateral movement and maintain accurate positioning, while the support portion ensures stability and heat insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional insulation frames with only flange portions are used, then the structure is simple, but rattling of electric storage devices in the direction parallel to the main plate portion cannot be suppressed
Solution Approach 1:
The insulation frame is segmented into functionally distinct portions: flange portions for positioning and a pressing portion for suppressing rattling. This segmentation allows each part to perform its specific function effectively, resolving the contradiction by adding only the necessary minimal structure (pressing portion) to achieve rattling suppression without over-complicating the overall design.
Solution Approach 2:
The pressing portion is provided locally at a specific position on the insulation frame rather than uniformly across the entire structure. This local quality approach suppresses rattling at the critical contact point while maintaining the simplicity of the rest of the insulation frame structure, thus resolving the contradiction between reliability improvement and device complexity.
2Manufacturing precision
If pressing portions are added to suppress lateral movement, then positioning accuracy is improved, but the insulation frame structure becomes more complex
Solution Approach 1:
The insulation frame is divided into distinct functional segments: flange portions for positioning and a pressing portion for movement suppression. This segmentation enables precise positioning (improving manufacturing precision) while keeping each segment's structure simple and modular, thus resolving the contradiction between positioning accuracy and structural complexity.
Solution Approach 2:
Instead of making the entire insulation frame complex to achieve positioning accuracy, the invention inverts the approach by adding a simple, localized pressing portion that works in conjunction with the simple flange portions. This inversion resolves the contradiction by achieving high positioning accuracy through a minimal structural addition rather than overall complexity.
3Stability of the object's composition
If the insulation frame tightly contacts the electric storage device to prevent movement, then positioning stability is improved, but heat conduction between components increases
Solution Approach 1:
The pressing portion provides localized contact for positioning stability only where necessary, rather than creating widespread tight contact across the entire insulation frame. This local quality approach maintains positioning stability at the contact point while minimizing overall heat conduction, thus resolving the contradiction between stability improvement and harmful heat transfer.
Solution Approach 2:
The insulation frame's contact with the electric storage device is segmented into discrete pressing points rather than continuous contact. This segmentation maintains positioning stability through focused pressure while reducing total contact area, thereby minimizing heat conduction and resolving the contradiction between stability and heat insulation.

AI summary
An electric storage apparatus includes an insulation frame and electric storage device. The insulation frame includes a main plate portion in contact with the electric storage device, a first flange portion provided at one end portion of the main plate portion in a predetermined direction parallel to the main plate portion, and second flange portion provided at the other end portion of the main plate portion in the predetermined direction. The first flange portion has a pressing portion including a projecting portion projecting to be pressed on the electric storage device. The second flange portion includes a support portion which is in contact with the electric storage device on an opposite side with respect to the projecting portion.
