Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mooring line retrieval systems in the maritime industry and brake wheel turning systems in the railroad industry are not safe, convenient, or economical, lacking efficient and cost-effective solutions for handling these tasks.
Innovation Solution
A multi-purpose tool system with a handle section featuring a sliding interior and exterior tube, a locking mechanism with a cylindrical finger, and a head with wings and notches for secure contact with wheels and ropes, allowing for length adjustment and facilitating safe, convenient, and economical operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing mooring line retrieval systems and brake wheel turning systems are used separately, then each system can perform its specific function, but the overall system complexity increases and operational convenience decreases
Solution Approach 1:
The patent creates a single tool system that can perform multiple functions: turning brake wheels in the railroad industry and retrieving mooring lines in the maritime industry. The head section is designed with universal features (wings, notches, central tube) that can engage with both brake wheels and mooring lines, eliminating the need for separate specialized tools for each application.
2Adaptability or versatility
If fixed-length handle systems are used, then the structure is simple, but the adaptability to different working conditions is limited
Solution Approach 1:
The handle section incorporates a telescopic mechanism with an interior tube that can slide within an exterior tube, allowing the handle length to be dynamically adjusted. This dynamic structure enables the tool to adapt to different working conditions and reach distances while maintaining operational simplicity through a locking mechanism.
3Strength
If heavy-duty materials are used to ensure strength and safety, then the tool can handle high loads, but the weight and manufacturing cost increase
Solution Approach 1:
The patent employs composite construction with a central tube made of high-strength material (such as steel) for load-bearing components, while other parts of the head section and handle may use lighter materials (such as aluminum or composite materials). This composite approach maintains the necessary strength and safety for handling heavy loads while reducing the overall weight and manufacturing cost of the tool system.

AI summary
A handle section has an interior tube slidably received in an exterior tube. A locking mechanism is secured to the exterior tube and includes a cylindrical finger reciprocable between an unlocking position and a locking position to allow for lengthening and shortening. A head is coupled to the interior tube. The head has a central tube formed as an extension of the interior tube. The head has a first wing with a first upper edge extending horizontally across the first wing. The first wing has a first outer edge extending vertically from the first wing parallel with and spaced from the central tube. The first wing has a first lower edge extending in a major arc between the first outer edge and the central tube.
