Solution Approach 1:

The system uses sensors to automatically detect cable position and the feed mechanism to self-adjust cable insertion, eliminating the need for manual alignment operations while maintaining precision

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical alignment operations are replaced with an automated system combining sensors for detection and a controlled feed mechanism for precise cable positioning and insertion

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If manual cable processing is used, then labor costs are incurred, but cycle time increases and productivity decreases

Engineering Contradiction:
Improvesolder sleeve installation productivityVSAvoidcable processing automation
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The system performs cable positioning, insertion, and processing operations automatically through integrated sensors and actuators, enabling the equipment to service itself without manual intervention for each cable

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The automated system enables continuous processing of cables through the production line, eliminating idle time between operations and maintaining constant productive action throughout the cable assembly process

AI summary

An automated system (110, 111) for processing an end (10a) of a cable (10). The system includes: a cable delivery system (60); a cable processing module (30); a pallet (64) supported by the cable delivery system; a drive wheel (16) rotatably coupled to the pallet; a motor (72) operatively coupled for driving rotation of the drive wheel; and an idler wheel (18) rotatably coupled to the pallet and forming a nip with the drive wheel. The cable processing module includes cable processing equipment (24) configured to perform an operation on an end of a cable and a computer system (162). The computer system is configured to: (a) cause the drive wheel to rotate in a cable pushing direction to cause a specified length of cable to be inserted into the cable processing equipment; (b) activate the cable processing equipment to perform an operation on the inserted end of the cable; and (c) cause the drive wheel to rotate in a cable pulling direction to cause the specified length of cable to be removed from the cable processing equipment.
