Solution Overview

Problem

Existing cable processing devices require cumbersome setup processes, involving frequent switching between central control units and processing stations, which increases operational risks and inefficiencies, especially when adapting to different crimp contacts and grommets.

Innovation Solution

Incorporating local operating units at each processing station, allowing for independent setup and control, with separate input means for initiating and confirming machining processes, ensuring safe and efficient operation by preventing one-handed operation and reducing the need for central control unit interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a central control unit is used to control all processing stations, then production operations can be monitored and controlled centrally, but the setup process becomes cumbersome and time-consuming due to frequent switching between central control unit and processing stations

Engineering Contradiction:
Improveproduction operation efficiencyVSAvoidsetup time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The control system is segmented into a central control unit for production operations and local operating units for setup operations. Each processing station is equipped with its own local operating unit, allowing operators to perform setup tasks directly at the station without returning to the central control unit. This segmentation resolves the contradiction by enabling simultaneous local setup and central production monitoring.

Inventive Principle:
Principle #1Segmentation

2Reliability

If setup operations are performed by switching between central control unit and processing stations, then central monitoring is maintained, but operational safety decreases due to increased risk exposure for operators

Engineering Contradiction:
Improvecentral control reliabilityVSAvoidoperator safety risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Local operating units serve as intermediaries between the central control unit and the processing stations during setup operations. These local units receive setup commands locally and execute them at the processing station, eliminating the need for operators to physically move between the central control unit and processing stations. This intermediary approach maintains system reliability while reducing operator exposure to harmful factors.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If local operating units are added to processing stations, then setup operations become faster and safer, but device complexity increases

Engineering Contradiction:
Improvesetup operation easeVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The local operating units are designed with universal functionality that can handle multiple setup tasks across different processing stations. Each local operating unit can control its associated processing station for various operations (stripping, crimping, grommet installation), reducing the need for station-specific control interfaces. This multi-functionality approach increases ease of operation while minimizing the increase in overall system complexity.

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

AI summary

A cable processing unit (1) for cable assembly has local control units (10) for locally setting up the processing stations (2, 3, 4), for example, a crimping station (4). The local control unit (10) of the crimping station (4) has a trigger button (11) for initiating the processing process and an enabling button (13) for confirming whether the crimping process should be carried out. The processing process can only be started if the trigger button (11) and the enabling button (13) are pressed simultaneously. The local control unit (10) also includes a cable call button (12) for controlling a feed unit (8) for feeding a cable end to the crimping station (4).
