Battery Wiring Module Terminal Mounting Recesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery wiring modules face challenges in easily mounting module-side terminals to the housing due to potential contact issues around holes or depressions, leading to inefficiencies in the mounting process.
Innovation Solution
The battery wiring module incorporates terminal accommodating portions with recesses lower than the terminal seat surfaces and inclined surfaces to guide and securely insert module-side terminals, along with varying insertion port widths to prevent erroneous mounting, ensuring easy and accurate placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If module-side terminals are partially inserted into holes or depressions in the housing to restrict movement, then terminal positioning is improved, but mounting becomes difficult due to contact around the holes
Solution Approach 1:
The terminal accommodating portion is divided into multiple functional zones: an insertion port for terminal entry, a recessed portion for positioning, and a terminal seat surface for final placement. This segmentation allows each zone to perform its specific function without interfering with others, enabling easy mounting while ensuring stable positioning.
Solution Approach 2:
The recessed portion acts as an intermediary element between the insertion port and the terminal seat surface. It provides a transition zone that guides the terminal during insertion while preventing contact with surrounding structures, thus facilitating easy mounting without compromising positioning stability.
2Ease of manufacture
If standard insertion ports are used without width variations, then manufacturing is simpler, but erroneous mounting cannot be prevented
Solution Approach 1:
Different insertion ports are designed with different widths to match the corresponding terminal sizes. This asymmetric design creates a unique fit for each terminal-insertion port pair, preventing erroneous mounting while maintaining manufacturing feasibility through standard variable-dimension practices.
3Stability of the object's composition
If recesses are made deeper to improve terminal securing, then terminal positioning stability is improved, but manufacturing complexity increases
Solution Approach 1:
The recessed portion is designed with specific dimensional parameters (depth and width) that are optimized for terminal securing without excessive complexity. The local geometry provides sufficient securing capability while maintaining overall structural simplicity and ease of manufacturing.
