Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical sewer cleaning tools lack a versatile and efficient means to attach and detach components securely, especially in varying sewer cable configurations, and do not provide adequate illumination or cable management during use.
Innovation Solution
The universal coupling pin key, comprising a cotter pin tool with a composite prism structure, a grip with integrated illumination, a retractable tether, and a cable management system, allows secure attachment and detachment of mechanical structures, adjusts to different sewer cable configurations, and provides adjustable reach and illumination for improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing mechanical sewer cleaning tools are used, then the basic cleaning function is provided, but the attachment and detachment of components is insecure and lacks versatility across varying sewer cable configurations
Solution Approach 1:
The coupling pin key is designed with a universal structure that can attach to different sewer cable configurations through its composite prism structure and multiple engagement surfaces. The tool serves multiple functions: securing cables, illuminating work areas, and providing cable management, making it adaptable across varying configurations while maintaining secure attachment through its specialized geometry
Solution Approach 2:
The coupling pin key employs a composite structure combining different geometric forms (prism shapes, cylindrical elements, and planar surfaces) integrated into a single tool. This composite design allows the tool to engage with various cable configurations while maintaining structural integrity and secure attachment through the synergistic combination of different geometric elements
2Ease of operation
If existing mechanical sewer cleaning tools are used, then the cleaning operation can proceed, but adequate illumination and cable management are not provided
Solution Approach 1:
The coupling pin key merges multiple previously separate functions into a single integrated tool: the mechanical coupling function, the illumination function (via integrated LED light source), and the cable management function (via retractable tether). This consolidation improves ease of operation by providing all necessary functions in one tool while managing complexity through integrated design
3Ease of operation
If a multifunctional tool with illumination and cable management is created, then usability is improved, but the tool structure becomes more complex
Solution Approach 1:
The coupling pin key incorporates dynamic elements including a retractable tether that can extend and retract to provide adjustable reach, and an integrated illumination system that can be activated as needed. These dynamic features improve usability by allowing adjustment of tool reach and lighting conditions while managing structural complexity through compact, integrated mechanisms

AI summary
The universal coupling pin key is a fastening device. The universal coupling pin key forms a detent that attaches a first mechanical structure to a second mechanical structure. The universal coupling pin key further forms a simple tool that dislodges or prys apart a fastened mechanical structure formed from two components. The universal coupling pin key comprises a tool, a grip, a retractable tether, and a cable management system. The tool is the mechanical structure of the universal coupling pin key that fastens and detaches the mechanical structures. The grip is a handle used to manipulate the tool. The retractable tether attaches the tool and the grip to the cable management system. The cable management system deploys and retracts the tether. The cable management system further anchors the universal coupling pin key to an anchor point.
