Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible circuit boards in battery technology are prone to warping during transportation, leading to abnormalities in battery sampling due to inadequate fixing methods that are designed for hard circuit boards and occupy excessive space, causing scratches and instability.
Innovation Solution
A fixing bracket for flexible circuit boards with a connecting portion and a fixing portion that securely attaches to a target component, using protruding components and snap-fit structures to prevent warping and ensure stability, while also accommodating external components for sampling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional fixing methods designed for hard circuit boards are used, then fixing strength is improved, but the flexible circuit board warps and causes sampling abnormalities
Solution Approach 1:
The patent uses a flexible circuit board with a thin film structure that can be bent and conform to the battery surface, replacing traditional rigid fixing methods. The flexible nature of the circuit board allows it to adapt to the battery's shape without causing warping, while maintaining reliable electrical connections for sampling.
2Strength
If traditional fixing methods are used, then fixing strength is improved, but the flexible circuit board is scratched and stability deteriorates
Solution Approach 1:
The patent introduces a protective layer or adhesive intermediary between the fixing structure and the flexible circuit board. This intermediary prevents direct contact that would cause scratches, while still providing sufficient fixing strength to maintain stability during battery assembly and operation.
3Stability of the object's composition
If fixing brackets are designed for hard circuit boards, then fixing stability is improved, but device complexity increases and automation becomes difficult
Solution Approach 1:
The patent extracts the essential fixing function from complex bracket structures and implements it through simplified adhesive bonding or integrated mounting features directly on the battery housing. This eliminates the need for separate fixing brackets while maintaining stability and enabling automated assembly processes.
Solution Approach 2:
The battery housing structure is designed to serve multiple functions: it provides structural support, mounting surfaces for the flexible circuit board, and integration points for sampling components. This multi-functionality eliminates the need for dedicated fixing brackets, reducing overall device complexity while maintaining fixing stability.
4Strength
If traditional fixing methods are used, then fixing capability is improved, but space occupation increases
Solution Approach 1:
The patent merges the fixing function with the battery housing structure itself, eliminating the need for separate fixing brackets. The housing is designed with integrated mounting features that provide fixing capability while occupying minimal space, allowing for more efficient battery pack design and component arrangement.
