CCS Assembly Sensor Retention for Stable Battery Temperature Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing CCS assemblies face issues with the temperature obtaining member detaching from the plastic bracket due to a small contact area, leading to unstable temperature monitoring in battery groups.
Innovation Solution
The CCS assembly incorporates a plastic bracket with a through groove and a temperature obtaining member with an encapsulation member, featuring a connection portion that includes a protrusion and pressing block to secure the temperature obtaining member, along with a compressible layer and adhesive layers for enhanced stability and adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the temperature obtaining member is directly fixed to the plastic bracket by back adhesive, then the mounting process is simple, but the contact area is small and the temperature obtaining member may be easily detached
Solution Approach 1:
The invention divides the mounting system into multiple components: the plastic bracket, the temperature obtaining member, and a connection portion with pressing blocks. This segmentation allows each component to perform its specific function - the pressing blocks provide mechanical pressure while the adhesive provides bonding, together ensuring both simple mounting and reliable fixation.
Solution Approach 2:
The invention combines mechanical connection (pressing blocks applying pressure) and chemical connection (adhesive bonding) into a unified connection portion. This merging of connection methods ensures that the temperature obtaining member is both simply mounted and reliably fixed, resolving the contradiction between ease of manufacture and mounting stability.
2Volume of moving object
If the temperature obtaining member has a water-droplet shape with curved outer surface, then the design is compact and fits the battery group, but the contact area with the plastic bracket is reduced
Solution Approach 1:
The connection portion acts as an intermediary between the curved temperature obtaining member and the plastic bracket. The pressing blocks in the connection portion provide additional contact points and pressure distribution, enabling reliable mounting while preserving the compact water-droplet shape of the temperature obtaining member.
Solution Approach 2:
The invention addresses the contact area issue by transitioning from a single-plane contact problem to a multi-dimensional solution. The connection portion with pressing blocks distributed on different sides of the through groove creates contact points in multiple spatial dimensions, effectively increasing the overall contact and pressure distribution without changing the water-droplet shape.
