Solution Overview
Problem
Conventional screw-based fastening methods make it difficult to repeatedly and quickly connect or disconnect objects, leading to challenges in assembly and disassembly processes.
Innovation Solution
An operating lever assembly with a fastening member and a lever member, featuring retaining sections, receiving spaces, and locating sections that allow for elastic deformation and movement, enabling quick and repeated fastening and releasing of objects through a connecting section and push sections for leverage assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If screw-based fastening is used to firmly hold two objects together, then connection stability is improved, but ease of repeated assembly and disassembly deteriorates
Solution Approach 1:
The fastening member is designed with a movable lever member that can transition between locked and unlocked positions. The lever member rotates about a connecting section, dynamically changing the engagement state between locating sections and enabling quick assembly/disassembly while maintaining stable connection when engaged
Solution Approach 2:
The fastening member is divided into distinct functional sections: a retaining section for holding objects, a receiving space for the lever member, and locating sections for positioning. This segmentation allows independent optimization of each component's function, achieving both stability and ease of operation
2Strength
If screw-based fastening is used to ensure firm connection, then connection strength is improved, but operational efficiency deteriorates
Solution Approach 1:
The lever member incorporates a push section that, when actuated, automatically triggers the releasing action. The locating sections self-align and self-lock into the mating locating sections, eliminating the need for manual screw tightening while maintaining strong connection, thereby improving operational efficiency
Solution Approach 2:
The lever member features a curved pushing path that provides mechanical advantage during actuation. This curved geometry amplifies the user's input force, enabling easy manipulation of the fastening mechanism while maintaining strong connection strength, thus improving operational efficiency

AI summary
An operating lever assembly includes a fastening member having a retaining section releasably fastened to a first object, a receiving space and a locating section; and a lever member having a mating locating section and being movably connected at an end to the receiving space and at another end to a second object. Alternatively, the fastening member includes a retaining section and a locating section; and the lever member includes a mating locating section and a receiving space, to which the fastening member is movably connected. The fastening member can be pushed to release the retaining section from the first object, while the lever member is moved in the receiving space and the locating section is engaged with the mating locating section to hold the fastening member to the lever member, allowing the first object to be repeatedly and quickly separated from or fastened to the second object.
