Bicycle Mounting Clamp With Adjustable Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle operating devices lack an efficient and adjustable mechanism for mounting and positioning operating units on bicycle tube members, leading to suboptimal operation and comfort for riders.
Innovation Solution
A bicycle operating device featuring a mounting clamp with a first and second radius portion, an adapter member with a connecting portion, and a restricting structure, allowing for adjustable positioning in both axial and circumferential directions, enabling secure attachment and optimal placement of operating units on bicycle tube members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed mounting clamp structure is used, then the device is simple in structure, but the positioning flexibility and rider comfort are reduced
Solution Approach 1:
The mounting clamp is divided into multiple functional segments: a base clamp portion for attachment to the bicycle tube member, an adapter member with connecting portion for intermediate connection, and an operating unit portion. This segmentation allows each part to perform its specific function while enabling overall positioning flexibility without excessive complexity.
Solution Approach 2:
The mounting clamp incorporates adjustable positioning mechanisms that allow dynamic adjustment of the operating unit's position relative to the bicycle tube member. The adapter member can be positioned at different locations along the tube member, and the connecting portion allows for angular adjustment, providing dynamics to an otherwise static mounting structure.
2Ease of operation
If the operating unit is mounted directly to the bicycle tube member, then the mounting structure is simple, but the operational efficiency and rider comfort are suboptimal
Solution Approach 1:
The adapter member serves as an intermediary component between the bicycle tube member and the operating unit. It provides a connecting portion that interfaces with both the tube member and the operating unit, allowing for optimized positioning and operation while maintaining a relatively simple overall structure.
3Reliability
If the mounting clamp allows extensive adjustment, then rider comfort is improved, but the risk of improper installation and operational failure increases
Solution Approach 1:
The mounting clamp is designed with pre-defined adjustment positions and alignment features that guide proper installation. The adapter member includes positioning elements that ensure correct orientation and placement before final tightening, preventing improper installation while maintaining adjustment flexibility.
Solution Approach 2:
The mounting structure incorporates self-aligning and self-securing features that guide the rider through proper installation without requiring external assistance or complex procedures. The restricting structure automatically engages to secure the adapter member in valid positions, ensuring reliable installation while maintaining adjustability.

AI summary
A bicycle operating device comprises a mounting clamp and an adapter member. The mounting clamp is configured to be mounted to a bicycle tube member and comprises a first radius portion, a second radius portion, and a clamp opening. The first radius portion defines a first inner radius. The second radius portion defines a second inner radius different from the first inner radius. The bicycle tube member is to extend through the clamp opening. The clamp opening is defined by the first radius portion and the second radius portion. The adapter member is configured to be provided between the second radius portion and the bicycle tube member in a state where the mounting clamp is mounted to the bicycle tube member.
