Bicycle Lever Rest Position Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle control devices lack an efficient mechanism for adjusting the rest position of operating levers, which can lead to discomfort and reduced control for riders, especially during long rides.
Innovation Solution
A bicycle control device with a mounting bracket and pivotally arranged levers that allow for adjustable rest positions, featuring a lever adjustment arrangement using a setting screw to adjust the rest position of the first operating lever relative to the mounting bracket around a second operating axis, enabling a comfortable grip and improved control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lever rest position is fixed, then the device structure is simple, but rider comfort and control are reduced
Solution Approach 1:
The patent applies the dynamics principle by making the lever rest position adjustable rather than fixed. The adjustment arrangement allows the rest position to be changed according to rider preferences, transforming a static structure into a dynamic one that can adapt to different operating conditions and user needs, thereby improving comfort and control without excessive complexity
Solution Approach 2:
The patent implements parameter changes by allowing the rest position parameter of the lever to be modified through the adjustment arrangement. This enables the system to optimize its operational parameters for different riders and riding conditions, improving ease of operation while maintaining a relatively simple structural implementation through mechanisms like setting screws or adjustable stops
2Adaptability or versatility
If the lever rest position is adjustable, then rider comfort and control are improved, but the device structure becomes more complex
Solution Approach 1:
The adjustment arrangement enables modification of the rest position parameter to suit different rider preferences and riding conditions. This parameter adaptability is achieved through relatively simple mechanical means such as adjustable stops or setting screws, providing versatility without proportionally increasing device complexity
Solution Approach 2:
The system transitions from a static fixed rest position to a dynamic adjustable rest position, allowing the device to adapt to different users and conditions. This dynamic capability is implemented through an adjustment mechanism that maintains structural simplicity while providing the needed versatility
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adjustable rest position enhances rider comfort and control by allowing for personalized lever positioning, reducing fatigue and improving operational efficiency during cycling.
Implementation Method 1
The first lever is pivotally arranged relative to the mounting bracket about a first axis and about a second axis being non-parallel to the first axis. The first lever is configured relative to the mounting bracket such that a free end of the first lever moves closer to the mounting bracket as the first lever pivots about the first axis from a rest position to an operated position.
Implementation Method 2
The adjustment arrangement adjusts the rest position of the first lever relative to the mounting bracket around the second operating axis.
