Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thread die holders are inconvenient for switching between different size thread dies and prone to loose set screws, which can cause the thread die to fall out.
Innovation Solution
A thread die retaining socket with a plunge component and retaining means, such as a magnetic washer or spring-and-ball detent mechanism, that allows easy insertion and ejection of thread dies, facilitating quick changes and secure retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If set screws are used to retain the thread die in the socket, then the thread die can be held securely, but the set screws can become loose and the thread die can fall out, and it is inconvenient when different size thread dies are required
Solution Approach 1:
The patent employs a dynamic retention system where a spring-loaded plunger with a spherical tip interacts with a corresponding recess in the thread die. This dynamic mechanism automatically adjusts to different thread die sizes and maintains secure retention without requiring manual adjustment of set screws. The spring force provides consistent retention pressure while allowing easy insertion and removal of different thread dies by simply pressing the plunger.
Solution Approach 2:
The retention mechanism is designed to be self-adjusting and self-retaining. When a thread die is inserted, the spring-loaded plunger automatically engages with the die's recess, providing secure retention without requiring user intervention to tighten set screws. The system self-regulates the retention force through the spring mechanism, eliminating the need for manual adjustment and reducing the risk of loosening over time.
2Reliability
If set screws are used to retain the thread die, then the thread die can be held in place, but the set screws can become loose allowing the thread die to fall out
Solution Approach 1:
The patent extracts the problematic set screw mechanism and replaces it with a spring-loaded plunger system. This extraction eliminates the issues associated with set screws becoming loose while maintaining the essential function of secure retention. The plunger mechanism with its spring bias provides continuous retention force without the need for threaded fasteners that can loosen over time.
Solution Approach 2:
The patent substitutes the traditional mechanical set screw system with a spring-mechanical system. The spring-loaded plunger uses elastic potential energy stored in the spring to provide continuous retention force, replacing the friction-based retention of set screws. This substitution creates a more reliable retention mechanism that is less prone to loosening while maintaining mechanical simplicity.
3Device complexity
If a conventional socket design is used, then the structure is simple, but it is inconvenient when different size thread dies are required and the thread die can fall out
Solution Approach 1:
The patent creates a universal socket design that can accommodate multiple thread die sizes through the spring-loaded plunger mechanism. The plunger's spring force and spherical tip design allow it to adapt to different die dimensions while maintaining secure retention. This multi-functional approach enables a single socket to serve multiple purposes with different thread die sizes, enhancing versatility without requiring multiple specialized sockets.
Solution Approach 2:
The retention mechanism utilizes parameter changes in the spring compression to adapt to different thread die sizes. As thread dies of varying dimensions are inserted, the spring compresses to different extents, automatically adjusting the retention force to maintain optimal engagement. This parameter adjustment capability allows the same mechanical structure to effectively retain different sized thread dies without modification.
