Retractable Cable Spool With Clutch Bearing and Brake Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable spools lack functionality for efficient winding and unwinding, secure cable retention, and controlled cable removal, leading to inefficiencies in accessing and managing coiled cables.
Innovation Solution
A cable spool configuration with cylindrical lips, a clutch bearing for rotational axis, and a feed slot, along with a spool gear and brake mechanism, including a spring biased release lever, to facilitate controlled cable unwinding and rewinding, ensuring secure cable management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional passive cable spools are used, then the structure is simple, but the cable access efficiency and control functionality are poor
Solution Approach 1:
The spool is transformed from a passive static structure to an active dynamic system with clutch bearings that can switch between locked and unlocked states, enabling controlled cable unwinding and secure rewinding while maintaining operational efficiency
Solution Approach 2:
The spool system integrates multiple functions into a single device: cable storage, controlled unwinding via clutch mechanism, secure locking during rewinding, and cable guidance through feed slots, eliminating the need for separate components
2Ease of operation
If cable can be easily removed from spool, then cable access is quick, but cable retention and security are compromised
Solution Approach 1:
The clutch bearing provides dynamic control over cable retention, transitioning between a locked state that securely holds the cable during rewinding and an unlocked state that allows quick removal when needed, resolving the contradiction between security and ease of access
3Speed
If cable unwinding is unrestricted, then cable access is fast, but cable control and management are lost
Solution Approach 1:
The clutch mechanism enables dynamic control during cable unwinding, allowing the spool to rotate freely for quick cable access while preventing reverse rotation to maintain cable management control and prevent tangling
Solution Approach 2:
The clutch bearing provides mechanical feedback through its locked and unlocked states, automatically responding to cable tension and rotation direction to maintain optimal cable management without requiring external control systems

AI summary
A spool apparatus is described to include in one particular example a cable spool with a first cylindrical lip and a second cylindrical lip on an opposite side of the cable spool. A center of the spool includes a clutch bearing in the center of both the first cylindrical lip and the second cylindrical lip that provides a rotational axis for the cable spool to rotate around. The apparatus may also include a feed slot near the first cylindrical lip that provides a passage for cable to pass from the second cylindrical lip to the first cylindrical lip.
