Earth Terminal Mounting Tool for Vehicle Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional earth terminal mounting tools with linear plates face difficulties in mounting earth terminals from different directions, leading to potential intersections and instability of electric components due to voltage drops during large current flows.
Innovation Solution
A plate-like tool with bent earth terminals and locking portions allows for secure orientation and positioning of earth terminals from various directions, preventing intersections and minimizing noise from voltage drops by individual earth connection to the vehicle body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a linear plate structure is used for the earth terminal mounting tool, then earth terminals can be mounted from the same direction, but it becomes difficult to mount earth terminals from different directions without intersection
Solution Approach 1:
The earth terminal mounting tool transitions from a linear one-dimensional structure to a two-dimensional plate-like structure with multiple connecting sections arranged in different directions. This dimensional change allows earth terminals to be mounted from multiple directions simultaneously without intersection, resolving the contradiction between mounting simplicity and directional flexibility.
2Device complexity
If multiple earth wires are connected in parallel, then the number of openings is minimized, but voltage drop occurs during large current flow causing potential change
Solution Approach 1:
The earth terminal mounting tool divides the earth connection function into multiple independent earth connecting sections, each capable of individually earthing earth wires. This segmentation allows multiple earth connections to be made separately, preventing voltage drop and potential changes that occur with parallel connections, while still minimizing the number of openings required in the vehicle body.
3Adaptability or versatility
If earth terminals are mounted from different directions, then mounting flexibility is improved, but earth terminals may intersect with adjacent earth terminals
Solution Approach 1:
Different earth connecting sections of the plate-like tool are designed with locally optimized configurations suitable for mounting from specific directions. Each section has its own locking portions and structural characteristics tailored to its mounting direction, allowing multiple terminals to be mounted from different directions without intersection while maintaining high positioning accuracy.
