Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an electric wire transfer robot is used to automatically feed electric wires to the work bench, then the efficiency of the cutting operation is improved, but the equipment investment cost increases
Solution Approach 1:
The patent introduces a control device as an intermediary between the operator and the cutting operation. This control device receives information about the electric wire to be cut, determines the appropriate cutting length based on stored data, and provides visual guidance to the operator, thereby improving cutting efficiency without requiring expensive automated wire feeding equipment
Solution Approach 2:
The system enables the operator to perform the cutting operation with enhanced guidance rather than requiring full automation. The control device provides the necessary information (wire type, length, positioning) to the operator, allowing manual operation to achieve efficiency接近 automated systems while avoiding the high cost of automated wire transfer robots
2Device complexity
If electric wires are manually pulled out and fed to the work bench without automated assistance, then the equipment investment cost is reduced, but the efficiency of the cutting operation deteriorates
Solution Approach 1:
The control device provides real-time feedback to the operator during the cutting operation. It displays the type of electric wire to be cut, the required cutting length, and visual indicators for correct positioning, enabling the operator to perform manual cutting with efficiency comparable to automated systems
Solution Approach 2:
The control device performs preliminary actions by determining the cutting length and positioning information before the actual cutting operation. This advance preparation of information allows the operator to execute the cutting operation efficiently without needing automated wire feeding equipment
3Productivity
If full automation is implemented for wire feeding and cutting, then the cutting efficiency is maximized, but the operational complexity and cost increase
Solution Approach 1:
The system allows manual operation to serve itself with enhanced guidance. The control device handles the complex tasks of determining wire types, calculating cutting lengths, and providing visual positioning indicators, while the operator performs the simple physical act of cutting, thereby maximizing efficiency without the complexity of full automation
Solution Approach 2:
The control device acts as an intermediary that handles the complex information processing and decision-making, while the operator handles the physical execution. This division of labor maximizes cutting efficiency without requiring the operator to manage complex automated systems

AI summary
A wire harness-producing device configured to produce a wire harness by displaying a wire laying-out image in a full size in a length direction on a plurality of display devices, and laying out electric wires along the wire laying-out image. The wire harness-producing device includes an electric wire-feeding device to allow the electric wires to be manually pulled out, a storage section to store operation recipe information therein, and a displaying control section to perform a displaying control on the display devices. The operation recipe information includes lengths of the electric wires. When each of the electric wires to be laid out is pulled out, the displaying control section displays, on the display devices, a starting end location indicator indicating a location for a front end portion of each of the electric wires having been pulled out, based on the lengths of the electric wires in the operation recipe information.
