Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing human-powered vehicle operating devices lack adaptability to various specifications, making it difficult to seamlessly integrate and replace components such as electric components and switch units, which limits their versatility and functionality.
Innovation Solution
The operating device comprises a base structure, a switch unit, an electric component, and an electric-component housing that allows for easy detachment and reattachment, enabling the replacement of electric components and switch units, and includes features like a wireless communicator, power-supply accommodating space, and a housing fastener for secure and flexible mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operating device uses a fixed integrated structure, then the device structure is simple, but the adaptability to various specifications is poor
Solution Approach 1:
The operating device is divided into separate modular components: a base structure, an electric-component housing containing electric components, and a switch unit. These modules can be independently replaced or configured based on different specifications, enabling adaptability without requiring complete device redesign.
Solution Approach 2:
The base structure serves as a universal platform that can accommodate different electric-component housings and switch units through standardized mounting interfaces. This universal base allows the same platform to support multiple configurations for different vehicle types and specifications.
2Adaptability or versatility
If the electric component is permanently fixed to the base structure, then the mounting is stable, but the replacement and adaptation to different specifications is difficult
Solution Approach 1:
The mounting system transitions from a permanent fixed connection to a dynamic detachable connection. The electric-component housing can be detached from and reattached to the base structure, providing both stability during operation and ease of replacement when adaptation is needed.
Solution Approach 2:
The electric-component housing acts as an intermediary component between the base structure and the electric components. It provides a standardized interface for attachment and detachment, enabling easy replacement while maintaining stable mounting during use through proper fastening mechanisms.
3Adaptability or versatility
If the switch unit is permanently integrated, then the device structure is simplified, but the adaptability to different switch specifications is limited
Solution Approach 1:
The switch unit is separated as an independent detachable module from the base structure. This segmentation allows different switch units with various specifications to be mounted on the same base structure, providing adaptability while keeping the overall assembly process straightforward through standardized interfaces.
4Object-affected harmful factors
If the electric component is exposed without housing, then the device complexity is reduced, but the protection from environmental factors is insufficient
Solution Approach 1:
The electric-component housing serves multiple functions simultaneously: it provides environmental protection for the electric components, offers a standardized mounting interface for attachment to the base structure, and enables easy detachment for replacement. This multi-functional design provides protection without significantly increasing overall device complexity.
