Bicycle Shock Absorber Pad Locking for Easy Damping Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle shock absorbers with adjustable damping face difficulties in easy installation and removal of pads for adjusting the air chamber volume, requiring tight engagement that complicates the adjustment process.
Innovation Solution
A bicycle shock absorber structure featuring a ring-shaped pad with protrusion parts that engage with locking slots on a lid, allowing easy assembly and disassembly by rotating the pad relative to the lid, facilitating adjustment of damping without the need for excessive force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pad is added in the air chamber to adjust the initial volume, then the air pressure curve can be adjusted to fit different rider weights, but the pad and parts need to be tightly engaged which causes difficulty for users to install or remove the pad
Solution Approach 1:
The locking mechanism is divided into a locking part with locking slots and a ring-shaped pad with protrusion parts. The protrusion parts can be inserted into the locking slots to secure the pad, while still allowing easy installation and removal through rotational movement.
Solution Approach 2:
The locking mechanism transitions from a static tight engagement to a dynamic rotational locking system. The ring-shaped pad can be rotated relative to the lid, allowing the protrusion parts to engage with or disengage from the locking slots, making installation and removal straightforward.
2Reliability
If the pad is tightly engaged to achieve stable shock-absorbing effect, then the shock-absorbing performance is improved, but the structure becomes more complex and difficult to adjust
Solution Approach 1:
The locking structure is segmented into simple components: a locking part with slots and a ring-shaped pad with protrusions. This segmentation maintains reliability through proper engagement while minimizing overall structural complexity.
Solution Approach 2:
The protrusion parts act as intermediaries between the ring-shaped pad and the locking slots. They provide the necessary connection for stable shock-absorbing effect while simplifying the overall locking mechanism through their simple geometric form.

AI summary
A bicycle shock absorber structure includes a gas-tube housing, a lid, an axial rod, and a ring-shaped pad. The lid includes a locking part and a locking slot. The locking slot is disposed on the locking part. The axial rod is connected to the locking part along an axis direction. The ring-shaped pad includes a radial opening, an inner hole, and a protrusion part. The inner hole is communicated with the radial opening and for sleeving on the locking part. The protrusion part is disposed at an inner edge of the inner hole. The ring-shaped pad sleeves on the axial rod through the radial opening and moves to sleeve on the locking part. The protrusion part then protrudes into the locking slot. The ring-shaped pad is rotated relative to the lid such that an interference between the protrusion part and the locking slot is generated.
