Flexible Hinge Cable Attachment Prevents Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric cable fixing parts in bus bar modules project outward and can become obstacles, and are prone to vibration, especially when electric cables are not attached, leading to instability and potential damage.
Innovation Solution
The implementation of a flexible hinge-based electric cable attachment part that can be bent towards the lead-out opening and held in a bent state, preventing projection and vibration, and an integrated closing mechanism to secure the opening, using a shared end linking member design for cost reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electric cable fixing part is provided in a projecting manner from the housing member, then the electric cables can be easily attached and led out, but the projecting part becomes an obstacle at the end where cables are not drawn out and easily vibrates due to vehicle vibration
Solution Approach 1:
The electric cable fixing part is designed to be movable relative to the housing member through a hinge mechanism, allowing it to change position from projecting outward to folded inward. This dynamic configuration enables the part to adapt between providing cable attachment functionality when needed and avoiding vibration/obstacle issues when not in use
Solution Approach 2:
The position and orientation parameters of the electric cable fixing part are changed by allowing it to rotate or fold relative to the housing member. This parameter change transforms the part from a fixed projecting structure to a flexible component that can adjust its spatial configuration based on operational requirements
2Object-affected harmful factors
If the electric cable attachment part is made flexible with a hinge part, then it can be bent to avoid becoming an obstacle and reduce vibration, but the structure becomes more complex
Solution Approach 1:
The hinge mechanism is integrated directly into the electric cable fixing part structure, merging the attachment functionality with the folding mechanism. This integration eliminates the need for separate complex actuating systems while achieving the desired flexibility and vibration reduction
Solution Approach 2:
The electric cable fixing part uses its own structural design with the hinge to automatically achieve the folding motion needed to avoid obstacles and reduce vibration, without requiring external actuation systems or additional control mechanisms
