Solution Overview

Problem

Existing wire harness production methods for train vehicles face inefficiencies in displaying and utilizing long wire layouts, as conventional methods struggle to effectively manage and display the extensive lengths required, leading to suboptimal use of display devices.

Innovation Solution

A wire harness production device and method that utilizes multiple display devices arranged end-to-end, with a control system to display full-scale wire laying images, allowing for efficient use of display space by compartmentalizing the image and using transparent protecting covers to prevent damage and facilitate easy replacement, enabling precise and efficient wire laying operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a single display device is used to show wire laying images, then the display setup is simple, but the display area is insufficient for very long wire harnesses requiring several tens of meters

Engineering Contradiction:
Improvedisplay areaVSAvoiddisplay setup complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The wire laying image is divided and displayed across multiple display devices arranged in a matrix pattern, allowing the total display area to extend to several tens of meters while maintaining manageable individual device specifications and enabling efficient worker collaboration

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If multiple display devices are arranged to increase display area, then sufficient space is available for long wire harnesses, but the bezel portions create non-display regions that waste space

Engineering Contradiction:
Improveeffective display areaVSAvoiddisplay space loss
Core Design Contradiction:
Area of stationary objectVSLoss of substance

Solution Approach 1:

Adjacent display devices are positioned so their bezel portions overlap or touch, creating a continuous display surface where the non-display regions of one device are compensated by the display regions of neighboring devices, thereby maximizing the effective display area

Inventive Principle:
Principle #5Merging (Combining)

3Area of stationary object

If display devices are placed close together to form a matrix, then the overall display area is optimized, but the display portions may become misaligned creating gaps

Engineering Contradiction:
Improvetotal display areaVSAvoiddisplay alignment precision
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

The bezel portions of display devices are designed with specific dimensional characteristics that compensate for alignment tolerances, creating overlapping regions that ensure continuous coverage even when display portions are not perfectly aligned

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The display devices are arranged with intentional overlap of bezel portions beforehand, creating a buffer zone that prevents gaps from forming due to potential misalignment during installation or operation

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

4Manufacturing precision

If wire laying images are displayed at full scale, then precise wire laying can be performed, but the images require very large display areas that are difficult to manage

Engineering Contradiction:
Improvewire laying precisionVSAvoiddisplay management complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The full-scale wire laying image is segmented across multiple display devices in a matrix arrangement, allowing each individual device to display a manageable portion while collectively providing the complete full-scale view needed for precise wire laying

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The matrix of display devices functions as a unified large-scale display system while each individual device maintains standard specifications, enabling the system to handle very long wire harnesses of several tens of meters through coordinated multi-device operation

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A wire harness producing method configured to produce a wire harness by arranging a plurality of display devices end to end, each including a display portion and a bezel arranged around a periphery of the display portion, displaying a wire laying-out drawing on the display devices, and laying out an electric wire along the wire laying-out drawing. The method includes compartmentalizing a two-dimensional image of the wire harness into display regions to be displayed on the display portions of the display devices respectively and non-display regions corresponding to the bezels of the display devices respectively, with the display regions and the non-display regions conforming to sizes of the display portions and the bezels respectively, trimming the two-dimensional image to create wire laying-out image data composed of only the display regions, and displaying the wire laying-out drawing on the display devices, based on the wire laying-out image data.
