Wiring harness layout table with rotatable work surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for assembling aircraft wiring harnesses require frequent removal and replacement of heavy and complex wiring harnesses for testing and rework, leading to inefficiencies and ergonomic issues due to the unavailability of testing equipment.
Innovation Solution
A rotatable wiring harness layout table with multiple work surfaces and a rotation mechanism that allows for preparation of multiple wiring harnesses on the same table without removing previously assembled ones, enabling continuous work and easy rework without re-laying out the harnesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods remove and replace wiring harnesses for testing, then testing can be performed, but assembly time increases and ergonomic strain occurs
Solution Approach 1:
The table is segmented into multiple independent work surfaces (first work surface, second work surface) that can be used simultaneously or sequentially. This allows one surface to be used for assembly while another is used for testing, eliminating the need to remove and replace entire wiring harnesses.
Solution Approach 2:
The patent introduces a vertical/rotational dimension by making the table rotatable between different positions. This allows the same physical table to present different work surfaces at different orientations, enabling continuous workflow without removing harnesses.
2Reliability
If conventional methods remove and replace wiring harnesses for testing, then testing can be performed, but ergonomic performance deteriorates
Solution Approach 1:
By dividing the table into multiple work surfaces, the system eliminates the need to physically handle and relocate heavy wiring harnesses between different tables or locations, significantly improving ergonomic conditions.
Solution Approach 2:
The table provides self-service functionality by having multiple work surfaces available on the same stationary structure, allowing workers to transition between assembly and testing tasks without physically moving the harnesses themselves.
3Productivity
If multiple wiring harnesses are prepared on the same table, then continuous work is enabled, but device complexity increases
Solution Approach 1:
The table incorporates a rotatable component that can dynamically change orientation between different work surfaces. This dynamic feature allows the same physical structure to serve multiple functions, enabling continuous work across different harnesses without requiring multiple separate static tables.
Solution Approach 2:
The table is designed as a universal platform with multiple work surfaces that can handle different wiring harnesses. This multi-functionality allows a single table structure to replace multiple specialized tables, achieving continuous workflow while managing complexity through design integration.

AI summary
A table includes a frame, a rotatable component, and a rotation mechanism. The frame has a pair of rotation bearings. The rotatable component has a first rotation position and a second rotation position. The rotatable component includes a pair of pivot portions supported by the pair of rotation bearings. The rotatable component further includes a first work surface configured to support preparation of a first wiring harness in the first rotation position. The rotatable component further includes a second work surface configured to support preparation of a second wiring harness in the second rotation position. The rotation mechanism is coupled with the rotatable component and is configured to rotate the rotatable component between at least the first rotation position and the second rotation position.
