Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire arranging devices for electric vehicles face issues with voltage detecting wires intersecting and contacting each other, leading to potential damage due to friction and tension, especially when connectors are rearranged based on battery layouts and wiring board structures.
Innovation Solution
A wire arranging device with tray parts and bus bar containing rooms that guide wires from one terminal row to the opposite terminal row without intersection, using partition walls and locking mechanisms to prevent contact and allow flexible connector placement, reducing the need for additional protective measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voltage detecting wires are arranged in conventional wire arranging devices, then wires can be guided from terminal rows, but wires intersect and contact each other causing friction and tension damage
Solution Approach 1:
The patent introduces a third dimension by stacking tray parts vertically. The first tray part guides wires from the first terminal row, while the second tray part guides wires from the second terminal row. By arranging tray parts in the vertical direction (stacking them), wires from different terminal rows are separated in space, preventing intersection and contact while maintaining proper wire guidance.
Solution Approach 2:
The wire arranging device is segmented into multiple independent tray parts, each responsible for guiding wires from a specific terminal row. The first tray part handles wires from the first terminal row, and the second tray part handles wires from the second terminal row. This segmentation allows independent wire management and prevents interference between wires from different terminal rows.
2Adaptability or versatility
If connectors are rearranged based on battery layouts and wiring board structures, then adaptability improves, but wire intersections increase leading to contact and damage
Solution Approach 1:
By utilizing the vertical dimension through stacked tray parts, the device accommodates different connector placements and battery layouts without causing wire intersections. Each tray part can be independently configured to match specific battery arrangements, providing adaptability while maintaining wire separation through vertical stacking.
Solution Approach 2:
The stacked tray part structure serves multiple functions: it guides wires from different terminal rows, prevents wire intersections, accommodates various battery layouts, and supports flexible connector placements. This universal design allows the same basic structure to adapt to different configurations without compromising wire integrity.
3Reliability
If additional protective measures are added to prevent wire damage, then wire reliability improves, but device complexity and material costs increase
Solution Approach 1:
The tray parts serve as intermediary structures that physically separate and guide wires from different terminal rows. By introducing these intermediate guiding elements, wires are naturally prevented from intersecting and contacting each other, eliminating the need for additional protective measures like protective coatings or complex shielding while maintaining wire reliability.
