Solution Overview

Problem

Existing bicycle operation devices lack ease of adjustment for the position of the operation unit relative to the handlebar.

Innovation Solution

A bicycle operation device with a clamp and an operation unit that includes a housing with a wireless communicator, allowing for easy adjustment of the operation unit's position through a coupling member and a position adjustment mechanism, enabling attachment and detachment from the handlebar.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the operation unit is fixed to the handlebar with a conventional clamp, then the structure is simple, but the position adjustment is difficult

Engineering Contradiction:

Improveposition adjustmentVSAvoidclamp structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The clamp structure is divided into a clamp body and a separate position adjustment mechanism. The operation unit housing can be detached and reattached at different positions along the handlebar, allowing easy position adjustment without redesigning the entire clamp structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The clamp transitions from a fixed position design to an adjustable position design. The position adjustment mechanism allows the operation unit to be dynamically repositioned along the handlebar, providing flexibility while maintaining structural integrity through the clamp body.

Inventive Principle:

Principle #15Dynamics

2Reliability

If the wireless communicator is placed in the lower housing portion, then the structure is compact, but the wireless signal reception may be blocked

Engineering Contradiction:

Improvewireless communicationVSAvoidhousing arrangement

Core Design Contradiction:

ReliabilityVSShape

Solution Approach 1:

The wireless communicator is specifically positioned in the upper housing portion, which has different spatial characteristics compared to the lower housing portion. This local placement optimizes the wireless signal reception by positioning the communicator in a location less prone to signal blocking, while the lower housing portion can accommodate other components.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If the operation unit is made detachable for easy adjustment, then the position flexibility is improved, but the connection reliability may deteriorate

Engineering Contradiction:

Improveposition flexibilityVSAvoidconnection stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The clamp structure includes pre-designed attachment and detachment mechanisms that are prepared in advance. The operation unit housing can be easily attached or detached by simple operations, and the connection reliability is ensured through pre-engineered coupling structures that maintain stable connection during normal use.

Inventive Principle:

Principle #10Preliminary action
