Drain Cleaner Cable Decoupler Tool Cam Actuator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable decoupler tools for drain cleaner cables are difficult to separate, requiring manual force and often relying on pin keys, which can be cumbersome and inefficient for storage or when needing a shorter cable or different accessories.
Innovation Solution
A cable decoupler tool with a mouth to receive a circumferential portion of the cable and a pin key extending from the mouth, along with an actuator movable relative to the mouth, allowing for easy disengagement of the accessory from the cable, typically using a cam lobe mechanism for efficient separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pin keys are used to separate cables and drain cleaning tool, then the cables and tool can be separated, but the separation process becomes cumbersome and requires manual leverage
Solution Approach 1:
The coupling mechanism is segmented into distinct components: a cable assembly with cable retention feature, an accessory with accessory retention feature, and a decoupler tool. This segmentation allows each component to perform its specific function independently, making separation easier while maintaining connection security during use.
Solution Approach 2:
The decoupler tool acts as an intermediary device between the cable assembly and accessory. It features a first engagement feature that interfaces with the cable retention feature and a second engagement feature that interfaces with the accessory retention feature, mediating the separation process and eliminating the need for manual pin key manipulation.
2Adaptability or versatility
If cables are secured together to desired length, then flexibility for different applications is achieved, but separation for storage or different applications becomes difficult
Solution Approach 1:
The coupling system transitions from a static permanent connection to a dynamic reversible connection. The retention features are designed to maintain secure connection during operation but allow easy separation when needed, enabling the cable assembly to adapt between different length configurations based on application requirements.
Solution Approach 2:
The decoupler tool is designed with pre-configured engagement features that automatically align with and engage the retention features on the cable assembly and accessory. This preliminary configuration eliminates the need for manual alignment or complex manipulation during the separation process.
