Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness assembly methods lack efficiency and accuracy due to the absence of visual guidance and real-time instruction, leading to potential operator errors and increased production time.
Innovation Solution
A digital wire harness assembly system utilizing a transparent peg board with a rear-mounted visual display system, where a proprietary computer program illuminates peg holes and wire runs on the display, providing step-by-step instructions and video guidance to operators for precise assembly, and includes a quality control mode for inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wire harness assembly methods are used without visual guidance, then the assembly process is simpler in terms of equipment, but operator errors increase and production time increases
Solution Approach 1:
A transparent peg board is introduced as an intermediary between the physical wire harness components and the digital display system. The peg board allows operators to physically assemble components while the transparent nature enables simultaneous viewing of digital guidance instructions on the display behind it, reducing errors without requiring complex integration
Solution Approach 2:
Traditional mechanical assembly guidance methods (physical templates, written instructions) are replaced with a digital display system that provides visual guidance. The display shows illuminated peg hole patterns and step-by-step instructions, substituting physical guidance mechanisms with electronic visual information
2Productivity
If traditional assembly methods without real-time instructions are used, then the equipment setup is simpler, but production time increases due to lack of guidance
Solution Approach 1:
The system provides dynamic, step-by-step visual instructions that update in real-time as the operator progresses through the assembly process. The illuminated peg hole patterns and instruction sequences change dynamically to guide each specific step, enabling faster assembly without overwhelming the operator with static complex information
Solution Approach 2:
The assembly instructions are segmented into discrete steps, with each step showing only the relevant peg holes and actions needed at that moment. This segmentation of information reduces cognitive load and allows operators to work faster by focusing on one step at a time rather than viewing the entire complex assembly process simultaneously
3Difficulty of detecting and measuring
If quality control inspection is performed after harness removal, then the assembly process is faster, but detection of errors becomes more difficult
Solution Approach 1:
The system performs preliminary quality control by providing visual confirmation of correct component placement at each step through the illuminated peg hole patterns. Operators can verify their work in real-time against the displayed guidance before moving to the next step, detecting errors immediately rather than requiring separate post-assembly inspection
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system significantly reduces operator errors by providing clear visual guidance and real-time instructions, enhancing assembly precision and efficiency, while allowing for quality control verification before the harness is removed from the assembly area.
Implementation Method 1
A transparent peg board is mounted in front of a display system such as an LCD or plasma display

AI summary
An electronic wire harness assembly system having a transparent pegboard with a rear mounted digital display such as an LCD or plasma display is controlled by a proprietary software program running on a personal computer. The digital display provides peg location illumination, wire run path location illumination, connector shape illumination and location illumination, as well as cable tie location illumination. The operator is visually assisted with notes and videos displayed under the pegboard at the appropriate locations. The pegboard grid is registered to the digital display with simple mouse pointer clicks.
