Bicycle Stem Buffer Suspension Assembly Alignment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for assembling a bicycle suspension assembly are labor-intensive and time-consuming, as they require adjusting the position of a plum-shaped member without clear alignment verification, which can lead to deformation or damage.
Innovation Solution
A stem buffer suspension assembly structure that includes a main suspension stem, an upper end cover, and a lower pressing assembly, allowing for quick and convenient assembly by eliminating the need to adjust the plum-shaped member's position, and ensuring proper alignment through a specialized locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the plum-shaped member is knocked into position using a special tool, then the suspension assembly can be assembled, but the assembly process becomes labor-intensive and time-consuming due to repeated adjustments
Solution Approach 1:
The patent applies preliminary action by pre-positioning the plum-shaped member at the bottom of the stem channel before inserting the suspension assembly. The positioning ring member with its specific structure (flange, positioning groove, and engagement features) is预先 installed to guide and align the suspension assembly automatically during insertion, eliminating the need for repeated knocking and adjustment operations.
2Manufacturing precision
If the plum-shaped member is repeatedly knocked to adjust its position, then alignment can be achieved, but deformation or damage to the member or stem may occur
Solution Approach 1:
The patent introduces the positioning ring member as an intermediary component between the stem and the suspension assembly. This positioning ring member features a positioning groove and engagement structures that guide the suspension assembly into correct alignment without requiring forceful knocking, thereby preventing deformation or damage to the plum-shaped member or stem while achieving precise positioning.
3Device complexity
If no alignment verification method is provided, then the assembly process is simple, but it becomes impossible to check whether the plum-shaped member position is correct
Solution Approach 1:
The patent employs visual alignment verification through the positioning ring member's structure. The positioning groove and flange create visible reference features that allow assemblers to verify correct positioning of the plum-shaped member and suspension assembly alignment without adding complex measurement devices, maintaining simplicity while enabling position verification.
