Buoyant Fastener Structure for Quick Coupling and Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screw-based fixation techniques complicate assembly, make demounting difficult, and prevent adjustment-oriented movement of coupled objects.
Innovation Solution
A buoyant fastener structure comprising a body portion with a rotation-preventing and position-limiting portion, and a fastening element with corresponding features, allowing for repeated coupling and separation, and enabling the second object to move on the fastening element for position adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-based fixation is used, then objects are fixed in place securely, but assembly becomes difficult and demounting is complicated
Solution Approach 1:
The fastener is divided into two separate components: a body portion and a fastening element. The body portion remains fixed while the fastening element can be independently inserted and removed, allowing easy assembly and demounting while maintaining secure fixation when engaged.
Solution Approach 2:
The fastening element is designed to be dynamically insertable and removable from the body portion. The position-limiting portion allows the fastening element to move along the body portion for adjustment, then locks into place, providing both ease of operation and secure fixation.
2Reliability
If screw-based fixation is used, then objects are fixed securely, but adjustment-oriented movement becomes impossible
Solution Approach 1:
The position-limiting portion enables the fastening element to move dynamically along the body portion to adjust positions, then locks securely when engaged, providing both adaptability and reliability.
Solution Approach 2:
The fastener serves multiple functions: it provides secure fixation when engaged, allows position adjustment through movement along the body portion, and enables repeated assembly and disassembly. This multi-functionality resolves the contradiction between security and adjustability.
3Reliability
If conventional fixation methods are used, then objects are held in place, but repeated coupling and separation becomes difficult
Solution Approach 1:
By separating the fastener into a stationary body portion and a movable fastening element, the design enables rapid insertion and removal of the fastening element while maintaining secure holding when engaged, thus improving repeated assembly speed without compromising reliability.
Solution Approach 2:
The fastening element is designed to be self-contained with its own position-limiting features, allowing it to be quickly inserted and removed without requiring complex tools or procedures, thereby enhancing productivity for repeated coupling and separation operations.

AI summary
A buoyant fastener structure includes a body portion and a fastening element. The body portion has a rotation-preventing portion and a position-limiting portion. The fastening element has a position-corresponding rotation-preventing portion, a position-corresponding position-limiting portion and a fastening portion. The rotation-preventing portion and the position-corresponding rotation-preventing portion prevent each other from rotating. A rotation-preventing buoyancy level exists between the rotation-preventing portion and the position-corresponding rotation-preventing portion. The position-limiting portion corresponds in position to and limits the position of the position-corresponding position-limiting portion. Therefore, the body portion is coupled to a first object, whereas the fastening portion is coupled to or removed from a second object, so as for the first and second objects to be coupled together and separated, repeatedly and quickly. Furthermore, the second object coupled to the first object is movable on the fastening element to adjust the position of the second object.
