Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle electric control devices lack adjustability in stroke length, which can lead to discomfort and inefficiency due to variations in rider hand size and preference.
Innovation Solution
An electric control device with an adjustable stroke mechanism, featuring a base member, a movable lever, a signal generating unit, and an adjusting structure that allows for linear or angular adjustment of the signal generating unit's position relative to the lever's pivot axis, enabling customizable stroke length through threaded fasteners and adjustment openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stroke length of the movable member is fixed, then the device structure is simple, but it cannot accommodate different hand sizes and preferences
Solution Approach 1:
The patent applies the dynamics principle by making the stroke length adjustable rather than fixed. The movable member's stroke can be modified through an adjusting structure that changes the position of the signal generating unit or the pivot axis position, allowing the device to adapt to different user needs while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent implements parameter changes by providing adjustability in the stroke length parameter. Through the adjusting structure, users can modify the distance between the first and second positions of the movable member, changing the operational parameter to suit different hand sizes and preferences without fundamentally altering the device design.
2Ease of operation
If the stroke length is adjustable, then user comfort is improved, but the device structure becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the adjusting function into separate components. The adjusting structure is implemented as a distinct module that can independently modify the stroke length, separating the adjustment mechanism from the main actuating components. This modular approach improves user comfort while keeping the overall device structure organized and manageable.
3Adaptability or versatility
If the signal generating unit position is fixed, then the device is simpler to manufacture, but it cannot be adjusted for different pivot axis positions
Solution Approach 1:
The patent applies dynamics by making the signal generating unit's position adjustable relative to the pivot axis. The adjusting structure enables dynamic repositioning of the signal generating unit along the elongated bore or through angular adjustment, allowing adaptation to different pivot axis positions while maintaining manufacturing simplicity through standardized adjustment mechanisms.
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 stroke mechanism enhances user comfort and operational efficiency by allowing riders to customize the distance required to activate the control device, accommodating different hand sizes and preferences.
Implementation Method 1
The adjusting structure further includes a threaded fastener that extends through the elongated bore and is threaded to the signal generating unit so as to provide adjustability of the position of the signal generating unit.
Implementation Method 2
the lever returns to the first position after being moved to the second position by a biasing member that biases the lever toward the first position
