Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical systems for connecting and locking mechanical components often require significant effort and specialized tools, and can jam or be misused, lacking universal applicability for efficient conversion of rotation to linear motion and vice versa.
Innovation Solution
A radially engaging system utilizing Archimedean spiral curves in a rotator and guide channels to facilitate effortless extension and retraction of sliding members, allowing for easy connection and locking of mechanical components with minimal effort, featuring a housing with guide channels, sliding members with followers, and a rotator with guide curves based on the Archimedean spiral.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw fasteners are used to connect mechanical components, then connection strength is improved, but ease of operation deteriorates due to requiring specialized tools and significant effort
Solution Approach 1:
The patent inverts the traditional screw mechanism by using a rotator with guide curves that convert rotational motion into linear motion of sliding members, rather than using threaded screws that require rotational input. This inversion allows connection to be achieved through simple rotation without requiring threading operations, eliminating the need for specialized tools while maintaining connection strength through the sliding members and guide channels
2Reliability
If mechanical locks with reciprocating members are used, then locking capability is improved, but reliability deteriorates due to potential misuse, misalignment, and mechanical failure
Solution Approach 1:
The patent implements a self-aligning mechanism where the guide channels and guide curves automatically guide the sliding members into proper alignment during rotation. The geometry of the guide curves ensures that the sliding members follow a predetermined path, eliminating misalignment issues. The system also prevents misuse by design, as the locking mechanism can only be actuated through the specific rotational motion that follows the guide curves, making it resistant to unauthorized or incorrect operation
3Reliability
If complex locking mechanisms are used to prevent misuse, then security is improved, but device complexity increases leading to more potential failure points
Solution Approach 1:
The patent creates a multi-functional system where the rotator with guide curves simultaneously provides motion conversion (rotation to linear), positioning (alignment of sliding members), and locking control (prevention of misuse). The guide channels serve multiple purposes: guiding the sliding members, defining the motion path, and ensuring proper engagement. This consolidation of multiple functions into unified components reduces the number of separate parts and potential failure points while maintaining security and reliability

Function Achieved in This Case
Enables smooth and effortless conversion of rotational to linear motion and vice versa, reducing the effort required for operation and preventing jamming, while providing a secure and proprietary locking mechanism for mechanical components.
Implementation Method 1
The rotator includes at least one guide curve based upon an Archimedian spiral. The follower rides inside the guide curve. Selective rotation of the rotator converts the rotation into linear movement of the connected sliding member.

AI summary
The radially engaging systems includes a housing having at least one guide channel formed therein. At least one sliding member is slidably received in the guide channel to selectively extend or retract therein in order to connect and lock mechanical components together. Each sliding member is provided with an elongate follower. A rotator is operatively mounted to the housing. The rotator includes at least one guide curve based upon an Archimedian spiral. The follower rides inside the guide curve. Selective rotation of the rotator converts the rotation into linear movement of the connected sliding member. Conversely, selective linear movement of the sliding member converts the same into rotation of the rotator.
