Adjustable Bicycle Electric Control Device Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle electric control devices lack adjustability to accommodate different hand sizes of riders, making it difficult to position user interface devices optimally for comfortable and efficient operation.
Innovation Solution
An electric control device for bicycles featuring a clamp member and a bracket member that are adjustable relative to each other, allowing for customizable positioning of user interface members, such as lever switches, through a guide portion and fastener system that enables angular or linear adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the control device is fixed in position, then the structure is simple, but it cannot accommodate different hand sizes of riders
Solution Approach 1:
The patent applies the dynamics principle by making the bracket member adjustable relative to the clamp member through a guide portion that allows movement in a first adjustment direction. The fastener can be positioned at different locations along the guide portion, enabling the control device to adapt to different hand sizes while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the control device is made adjustable, then it accommodates different riders, but the positioning precision is reduced
Solution Approach 1:
The patent applies segmentation by dividing the positioning system into discrete components: the guide portion with multiple predetermined positions and the fastener that can be secured at each position. This segmentation allows for adjustable positioning while maintaining manufacturing precision through standardized positioning locations.
3Ease of repair
If the bracket member is made detachable, then it is easier to adjust and repair, but the connection reliability is reduced
Solution Approach 1:
The patent applies dynamics by designing the fastener to be movable along the guide portion for adjustment purposes, yet capable of being securely fixed at predetermined positions. This dynamic design allows the bracket member to be easily adjusted and detached for repair while maintaining connection reliability when secured at the chosen position.
