Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible control levers for bicycles and motorcycles are complex in structure and assembly, require multiple elements to achieve multi-directional pivot or oscillation, and often have limited rotation angles, making them inconvenient to operate and prone to damage in impacts.
Innovation Solution
A collapsible control lever comprising an assembling member, a rotation seat, a first torsion spring, a handle, and a pivoting rod, where the handle features a ball socket and a ball head, allowing for three-dimensional angled folding with simplified structure and reduced elements, enabling non-directional movement and wider rotation angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple elements and complex structures are used to achieve multi-directional pivot or oscillation, then the reliability and protection against damage are improved, but the device complexity increases and manual adjustment is required post-impact
Solution Approach 1:
The patent combines multiple pivot functions into a single integrated ball socket joint. Instead of using separate pivot mechanisms for different directions, the ball socket allows the handle to pivot freely in multiple directions (upward, downward, leftward, rightward) simultaneously through one unified structure, eliminating the need for multiple separate elements and reducing assembly complexity
Solution Approach 2:
The patent employs a dynamic pivot design where the handle can oscillate and rotate freely within a wide range of motions without fixed limiting angles. The ball socket joint enables the handle to adapt its movement direction dynamically based on impact forces, allowing automatic reset without manual adjustment and improving reliability under various impact conditions
2Device complexity
If linear pivot mechanisms with limiting angles are used, then the structure is simpler, but the rotation angle is limited and manual adjustment is needed
Solution Approach 1:
The patent transitions from linear one-dimensional pivot mechanisms to a three-dimensional ball socket joint. This dimensional upgrade allows the handle to pivot freely in multiple directions (upward, downward, leftward, rightward) simultaneously, providing a wide rotation angle range without increasing structural complexity, and eliminating the need for manual adjustment after impact
3Adaptability or versatility
If fixed pivot positions with different directions are used, then multi-directional collapsible rotation is achieved, but more elements are needed and assembly becomes complicated
Solution Approach 1:
The patent merges multiple fixed pivot positions with different directions into a single ball socket joint. The ball socket inherently provides multi-directional rotation capabilities (upward, downward, leftward, rightward) through one unified structure, eliminating the need for multiple separate pivot elements and significantly simplifying assembly while maintaining adaptability

AI summary
A collapsible control lever comprises an assembling member, a rotation seat, a first torsion spring, an handle, and a pivoting rod. One end of the rotation seat is pivoted to the assembling member. The first torsion spring is assembled between the assembling member and the rotation seat. One end of the handle has a ball socket. One end of the pivoting rod has a ball head which is passing through and pivoted to the ball socket and the other end thereof is passing through and assembled to the rotation seat to provide to be folded and rotated in multiple angles with an external force. It provides a multi-angle collapsible control lever to increase the ranges of bending and rotation. A single element is provided a three-dimension range to achieve the effects of collapsing and rotating and the structure is simplified.
