Battery Sealing Member Recess Structure to Prevent Reverse Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sealing members often fit reversely, affecting sealing performance and fitting efficiency due to lack of clear mounting direction indicators.
Innovation Solution
A sealing member design featuring a recessed securing structure on its surface, which prevents reverse fitting by producing an obvious projection when mounted incorrectly, ensuring correct orientation and enhancing the sealing performance and fitting efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sealing members are fitted without clear mounting direction indicators, then the fitting process is simpler, but reverse fitting occurs affecting sealing performance and fitting efficiency
Solution Approach 1:
The securing structure incorporates an asymmetric recess design where the recess is positioned at a specific location on the securing structure. This asymmetric geometry creates a fool-proof mounting mechanism: when the sealing member is installed correctly, the recess aligns with the positioning structure allowing proper securing; when installed reversely, the recess creates an obvious projection that prevents incorrect engagement, thereby eliminating reverse fitting issues while maintaining fitting simplicity
Solution Approach 2:
The recess is pre-formed in the securing structure during manufacturing, creating a built-in mounting direction indicator before the actual fitting process. This preliminary geometric feature guides the operator to the correct mounting orientation without requiring additional markings or complex procedures, ensuring reliable sealing performance from the first installation attempt
2Device complexity
If sealing members lack reverse-fitting prevention features, then the device structure remains simple, but fitting efficiency decreases due to mounting errors
Solution Approach 1:
The recess in the securing structure creates an asymmetric geometry that serves as a built-in fool-proof mounting indicator. This simple asymmetric feature requires minimal additional structure while effectively preventing reverse fitting, thus maintaining device simplicity while significantly improving fitting efficiency by eliminating mounting errors
Solution Approach 2:
The recess introduces a dimensional feature (depth variation) to the otherwise simple securing structure surface. This dimensional change creates the projection effect that indicates mounting direction, adding functionality without substantially increasing structural complexity, thereby improving fitting efficiency while keeping the device design economical

AI summary
The present application provides a sealing member, a battery, and an electrical apparatus. The sealing member includes a main body and a securing structure disposed on the main body. The securing structure is connected to a positioning structure on a member to be sealed to secure the sealing member on the member to be sealed. A surface of the securing structure facing the member to be sealed is provided with a recess, and the recess is recessed in a direction away from the positioning structure to prevent the sealing member from being fitted reversely. The sealing member provided by the present application can prevent the sealing member from being fitted reversely.
