Movable Fastening Element for Quick Repeated Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening methods using screws make it difficult to assemble and disassemble objects quickly and repeatedly, as they often require significant effort and can be cumbersome.
Innovation Solution
A fastening element comprising a body portion and a movably combined fastening portion with a height limiting member that allows for quick assembly and separation of objects by limiting the distance between them, utilizing an elastic element for enhanced operation and adjustable floating amounts for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to combine objects, then the objects are fixed securely, but the assembly and disassembly process becomes difficult and time-consuming
Solution Approach 1:
The fastening element is divided into a body portion and a movable fastening portion that can be separated. The fastening portion can be independently operated to engage or disengage from the body portion, allowing quick release without removing the entire fastening element. This segmentation enables easy disassembly while maintaining secure fastening when engaged.
Solution Approach 2:
The fastening portion is designed to be movable relative to the body portion, transitioning between engaged and disengaged states. This dynamic structure allows the fastening element to switch between a secure locked state and an easily released state, solving the contradiction between strong fastening and easy assembly/disassembly.
2Reliability
If conventional fastening methods are used, then objects are securely combined, but repeated assembly and disassembly becomes cumbersome
Solution Approach 1:
The fastening portion is pre-configured with fastening portion limiting members that guide the engagement process. These limiting members are positioned in advance to ensure proper alignment and engagement, allowing rapid repeated assembly without compromising fastening reliability. The preliminary positioning structures enable quick engagement while maintaining secure connection.
3Ease of operation
If a movable fastening portion is used, then assembly and disassembly become easier, but the structure becomes more complex
Solution Approach 1:
The fastening portion is nested within or integrated with the body portion, with the movable components contained within the overall fastening element structure. This nesting approach allows the complex movable mechanism to be compactly integrated without significantly increasing the external dimensions or apparent complexity of the fastening element.
4Manufacturing precision
If fastening portion limiting members are added, then the fastening stroke is limited and positioning is improved, but the device complexity increases
Solution Approach 1:
The fastening portion limiting members are merged with the existing fastening portion structure rather than being separate additional components. The limiting members are integrated into the fastening portion itself, combining the limiting function with the fastening structure to achieve precise positioning without significantly increasing overall device complexity.

AI summary
A fastening element includes a body portion and a fastening portion. The body portion is used to assemble a first object. The fastening portion is movably combined in the body portion, the fastening portion is provided with a height limiting portion, and the fastening portion is used to assemble a second object. The height limiting portion is abutted against the second object or limits a fastening stroke of the fastening portion, or the height limiting portion limits a distance between the first object and the second object. Accordingly, the fastening element can quickly combine and separate at least two objects, and achieve the effect of combining and separating repeatedly and quickly.
