Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing human-powered vehicle operating devices lack flexibility and adjustability to accommodate various user inputs and vehicle configurations, leading to suboptimal operation and user experience.
Innovation Solution
The operating device comprises a base structure, a switch unit, and an additional switch unit, which are coupled to the base structure via an attachment axis, allowing for adjustable positioning and activation based on user inputs, with pivot axes and angles that can be adjusted to improve flexibility and operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the switch unit and additional switch unit are fixed to the base structure, then the device structure is simple, but the adaptability to different user inputs and vehicle configurations is poor
Solution Approach 1:
The patent applies the dynamics principle by making the switch unit and additional switch unit adjustable relative to the base structure through an attachment axis. This allows the switch units to be repositioned to accommodate different user inputs and vehicle configurations while maintaining a relatively simple overall device structure. The adjustability mechanism enables the system to adapt to various operating conditions without requiring complete structural redesign.
2Ease of operation
If the switch unit and additional switch unit are made adjustable about the attachment axis, then the flexibility and operability are improved, but the device complexity increases
Solution Approach 1:
The patent implements adjustability about the attachment axis to enable the switch units to be positioned optimally for different user inputs. This dynamic adjustment capability improves ease of operation by allowing adaptation to various riding positions and control preferences, while the adjustment mechanism remains integrated into the base structure to minimize overall complexity.
Solution Approach 2:
The attachment axis mechanism serves multiple functions: it provides adjustability for different user inputs, accommodates various vehicle configurations, and maintains structural integration. This multi-functionality approach improves operability while avoiding the need for separate adjustment mechanisms for each specific requirement.
3Adaptability or versatility
If the pivot axis and additional pivot axis are made adjustable relative to each other, then the flexibility of arrangement is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies adjustability to the pivot axes, allowing them to be positioned relative to each other to optimize the arrangement of switch units. This dynamic configuration capability enhances flexibility in accommodating different control scenarios, while the adjustment mechanism is designed to integrate with the base structure to manage manufacturing precision requirements.
