Button-Release Positioning Structure for Tool-Free Bolt Loosening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning structures are difficult to disassemble and assemble due to space limitations and tool accessibility issues, making the process time-consuming and challenging, especially when tools cannot reach the bolt head or apply sufficient force.
Innovation Solution
A positioning structure comprising a bush, a positioning washer with elastic pieces, and a button, where the button slides to deform the elastic pieces, allowing quick loosening of the bolt from the washer, facilitating easy disassembly and assembly through a two-way pressing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional bolt and screw hole engagement is used, then reliable fixation is achieved, but disassembly and assembly become time-consuming and difficult due to tool accessibility issues
Solution Approach 1:
The positioning structure is divided into modular components: a positioning washer with positioning elastic pieces, a bolt, and a button. This segmentation allows the fixation mechanism to be independently controlled and quickly released by pressing the button, which pushes the elastic pieces to disengage from the bolt threads, enabling rapid disassembly without tools.
Solution Approach 2:
The positioning elastic pieces are designed to be deformable, transitioning between engaged and disengaged states. When the button is pressed, the elastic pieces deform to release the bolt; when released, they return to their original shape to secure the bolt. This dynamic behavior enables quick transition between fixed and loose states without tools.
2Strength
If traditional bolt tightening is used, then secure fixation is achieved, but operation becomes difficult when tools cannot reach the bolt head or apply sufficient force
Solution Approach 1:
The positioning elastic pieces act as intermediaries between the button and the bolt. Pressing the button transfers force through the elastic pieces to the bolt threads, enabling force application in confined spaces where direct tool access to the bolt head is impossible. This intermediary mechanism solves the accessibility problem while maintaining fixation strength.
Solution Approach 2:
The positioning elastic pieces automatically engage with the bolt threads when the bolt is inserted, providing self-fixation without requiring external tools. The system serves itself by using the elastic deformation of the positioning pieces to secure the bolt in place, eliminating the need for tool-assisted tightening.
3Reliability
If conventional fixation methods are used, then reliable connection is achieved, but the disassembly mechanism becomes complex and non-intuitive
Solution Approach 1:
The release function is extracted and concentrated into a single button component. This button, when pressed, directly actuates the positioning elastic pieces to disengage from the bolt. By extracting the release mechanism into a dedicated, easily accessible component, the system achieves simple and intuitive operation while maintaining reliable connection through the positioning washer and elastic pieces.

AI summary
A positioning structure includes a first bush, a positioning washer, a bolt, and a button. The first bush has a first and a second opening. The positioning washer is fixed in the first bush, and includes a positioning hole aligned to the first opening and multiple positioning elastic pieces circumferentially arranged in the positioning hole. The bolt is adapted to be inserted into the first bush from the first opening and passes through the positioning hole. At least one of the positioning elastic pieces is engaged with a thread of the bolt. The button is inserted into the first bush from the second opening and contacts the positioning elastic pieces. The button is adapted to slide toward the first opening to push the positioning elastic pieces to deform, so that the positioning elastic pieces are separated from the thread, and the bolt is loosened from the positioning washer.
