Battery Module Wiring Harness Bracket for Vibration-Stable Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery module mounting and fixing modes lead to excessively long and loose acquisition wiring harnesses, which are prone to collision during vibration testing, causing signal acquisition failures.
Innovation Solution
A bracket assembly with a wiring harness bracket and a detachably connected fixing bracket, featuring a mounting portion with a protruding first connecting portion and a second connecting portion, securely integrates the connector and acquisition wiring harness to prevent loosening and collision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the acquisition wiring harness is mounted on the bracket assembly using existing mounting and fixing modes, then the wiring harness can be installed, but it becomes excessively long and loose, making it prone to collision during vibration testing
Solution Approach 1:
The bracket assembly is divided into two separate brackets: a first bracket for mounting the acquisition wiring harness and a second bracket for mounting the connector. This segmentation allows independent optimization of each bracket's function, enabling the wiring harness to be securely mounted without excessive length while keeping the connector mounting flexible and adjustable.
Solution Approach 2:
A detachable connection mechanism serves as an intermediary between the first bracket (wiring harness mounting) and the second bracket (connector mounting). This intermediary allows the two brackets to be connected or separated independently, enabling the wiring harness to be fixed securely while maintaining adjustability for the connector position to avoid collision during vibration testing.
2Ease of manufacture
If the acquisition wiring harness is made longer to accommodate mounting requirements, then it can be installed on the bracket assembly, but it becomes loose and prone to collision with other structures
Solution Approach 1:
By segmenting the mounting function into two separate brackets, the wiring harness length can be optimized to be just sufficient for connection without being excessively long. The first bracket provides secure mounting at the optimal position, eliminating the need for excessive wiring harness length that would cause looseness and collision risk.
Solution Approach 2:
The detachable connection mechanism acts as an intermediary that allows precise positioning of the wiring harness mounting point. This enables the wiring harness to be mounted at the optimal location with appropriate length, preventing both excessive length (looseness) and insufficient length (mounting difficulty).
3Ease of manufacture
If the connector is mounted directly on the bracket assembly, then it can be installed, but the limited space makes it difficult to ensure stable mounting
Solution Approach 1:
The connector mounting function is separated from the wiring harness mounting function by using a distinct second bracket. This segmentation provides a dedicated mounting structure for the connector, ensuring stable mounting even in limited space by optimizing the bracket design specifically for connector attachment requirements.
Solution Approach 2:
The detachable connection mechanism serves as an intermediary that provides a stable mounting base for the connector while allowing position adjustment. This intermediary structure enables reliable connector mounting in limited space by decoupling the connector mounting stability from the wiring harness mounting constraints.
4Device complexity
If a fixed mounting structure is used for both the wiring harness and connector, then the structure is simple, but it cannot provide flexible adjustment for optimal positioning
Solution Approach 1:
The bracket assembly incorporates a detachable connection mechanism that transforms a static fixed structure into a dynamic adjustable structure. The first and second brackets can be connected or separated, and their relative positions can be adjusted, providing flexibility for optimal positioning of both the wiring harness and connector while maintaining structural simplicity through modular design.
