Reel-Fed Claw Power Structure to Prevent Cable Wear and Entanglement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional claw machines experience cable wear and tear, obstructed player vision, and entanglement issues due to the elastic spiral cable's movement, leading to reduced player enthusiasm and potential damage.
Innovation Solution
A claw power supply structure utilizing a flexible cable with a reel and electrically conductive rings, where the flexible cable is wound on the reel and connected to the claw, eliminating rubbing and pulling, and ensuring the cable does not obstruct the player's view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an elastic spiral cable is used to power the claw, then the claw can be energized to control the electromagnetic coil, but the cable is constantly rubbed and shaken during operation, leading to wear and tear and potential wire breakage
Solution Approach 1:
The patent extracts the power supply function from the moving elastic spiral cable by introducing a separate rigid power supply structure fixed to the box body. This separates the power delivery system from the moving claw mechanism, eliminating the rubbing and shaking that caused cable wear while maintaining reliable power supply to the electromagnetic coil.
Solution Approach 2:
The patent introduces a rigid power supply cable as an intermediary element between the power source and the claw. This intermediary replaces the problematic elastic spiral cable, providing stable power transmission without the mechanical wear issues of the original flexible cable design.
2Ease of operation
If an elastic spiral cable is used to power the moving claw, then the claw can be controlled, but the shaking cable obstructs the player's line of sight and hinders judgment
Solution Approach 1:
The patent removes the elastic spiral cable from the visual field between the player and the claw. By using a rigid power supply structure fixed to the box body rather than a moving cable, the visual obstruction is eliminated while the claw control function is maintained through the separate power delivery system.
3Duration of action of moving object
If an elastic spiral cable is used to power the claw, then the claw can move up and down, but the cable may be entangled with the article and cause damage when pulled
Solution Approach 1:
The patent extracts the power supply function from the moving cable system entirely. The rigid power supply structure fixed to the box body provides power without moving with the claw, eliminating the entanglement risk with articles while the claw maintains its full movement range for catching objects.
