Bicycle Damper Annular Adjuster for In-Ride Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rear wheel dampers for bicycles are difficult to adjust during operation, especially in various installed situations, as adjustment members may not be easily accessible, requiring riders to stop and increasing the weight and susceptibility to failure with remote control configurations.
Innovation Solution
A damper device with an annular adjustment member rotatably accommodated within the housing, allowing for central operation and easy adjustment of operational settings, featuring a mechanical transmitting device with a plunger and swivel member to facilitate axial displacement and improve accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adjustment members are disposed at the end of the housing for compact structure, then device complexity is reduced, but ease of operation deteriorates when damper is mounted in certain positions
Solution Approach 1:
The adjustment member is moved from the traditional end-position (one-dimensional arrangement) to a central position on the housing (two-dimensional redistribution). This spatial reconfiguration allows the adjustment member to be accessible from the side of the housing, solving the accessibility problem for various mounting orientations without increasing overall device complexity.
2Ease of operation
If remote control equipment is added to allow adjustment during riding, then ease of operation is improved, but reliability deteriorates due to increased susceptibility to failure
Solution Approach 1:
The patent extracts the adjustment function from the traditional remote control system (cable-bound or wireless) and relocates it to a mechanical transmitting device integrated into the housing. This eliminates the need for separate power supplies, cables, or electronic components, thereby maintaining ease of operation during riding while significantly improving reliability by removing failure-prone remote control equipment.
3Ease of operation
If cable-bound or wireless remote control is implemented, then ease of operation is improved, but weight increases due to separate power supply requirements
Solution Approach 1:
The patent removes the separate power supply system required for wireless or cable-bound remote control and extracts the adjustment function to a mechanically-operated transmitting device. This eliminates the weight of batteries, power management circuits, and associated components, maintaining operational ease during riding while significantly reducing the overall weight of the bicycle system.

AI summary
A damper device for a bicycle having a housing extending in the axial direction and disposed therein, a chamber which forms a chamber volume that is sealed outwardly. The chamber volume extends in the axial direction from a first end to a second end. In the axial direction, at least one adjustment member is rotatably disposed between the ends of the chamber volume. The adjustment member is configured as an annular member and is rotatably received at the housing and surrounds at least part of the housing. By way of movement of the adjustment member, at least one operational setting of the damper device is changeable by means of a mechanical transmitting device.
