Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable harness production methods require separate technical drawings and manual adjustment of nails on wiring boards, leading to increased labor, paper waste, and inaccuracies due to shadowing and lack of automatic guidance for operators.
Innovation Solution
A programmable wiring board with a transparent work surface, projector, sensors, and automatic pin movement, where the pins rise and fall according to the projected image, and a control unit ensures accurate cable laying and testing, eliminating the need for multiple boards and reducing operator errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate technical drawings are printed for each cable harness, then cable harness production can be guided, but paper expense increases and environmental damage occurs
Solution Approach 1:
The patent replaces physical paper drawings with digital image projections displayed on a transparent screen. The projection device projects cable routing images onto the transparent work surface, eliminating the need for printed technical drawings while maintaining production guidance functionality.
2Adaptability or versatility
If manual adjustment of nails is performed on wiring boards, then cable routing can be configured, but labor force increases
Solution Approach 1:
The system automatically determines cable routing by detecting the projected image position and autonomously configuring the nail matrix structure without requiring manual operator intervention. The computer executes programs that control the projection and nail positioning automatically.
3Illumination intensity
If classical projection reflection is used, then technical drawings can be displayed, but shadowed areas and dark spots occur on the work area
Solution Approach 1:
The patent transitions from traditional 2D projection onto a flat surface to 3D spatial positioning using a transparent screen with a nail matrix structure. The projection device projects images through the transparent screen, and the computer controls nail positions in three-dimensional space, eliminating shadowing issues by changing the dimensional approach to display and interaction.
4Adaptability or versatility
If a single programmable wiring board is used, then economic loss is reduced, but the system complexity increases
Solution Approach 1:
The patent creates a universal programmable wiring board system that can produce different cable harnesses by loading different programs and projecting different images. The same physical board with nail matrix structure serves multiple cable routing configurations through software control, eliminating the need for multiple dedicated wiring boards.
