Solution Overview

Problem

Conventional bicycle braking systems with hydraulic pressure control units for antilock braking control often position these units near the handle, obstructing the placement of visually important equipment and complicating connections to components near the front wheel.

Innovation Solution

The hydraulic pressure control unit is mounted to the bicycle's front fork, allowing visually important equipment to be placed around the handle without obstruction and facilitating connections to components near the front wheel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the hydraulic pressure control unit is mounted near the handle, then the space for mounting is sufficient, but the placement of visually important equipment is obstructed

Engineering Contradiction:
Improvemounting spaceVSAvoidvisual perception of equipment
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The hydraulic pressure control unit is extracted from the handle periphery and relocated to the front fork area. This separation removes the obstruction to visually important equipment while maintaining adequate mounting space in the original handle area.

Inventive Principle:
Principle #2Taking out (Extraction)

2Area of stationary object

If the hydraulic pressure control unit is mounted near the handle, then mounting space is available, but the connection to components near the front wheel becomes complicated

Engineering Contradiction:
Improvemounting spaceVSAvoidconnection complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The hydraulic pressure control unit is extracted from the handle area and repositioned to the front fork area, which is physically closer to the front wheel components. This relocation shortens connection paths and reduces the complexity of hydraulic lines and electrical wiring.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mounting position is changed from the horizontal plane near the handle to the vertical plane near the front fork, creating a more direct spatial relationship with front wheel components and simplifying connections.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Area of stationary object

If the hydraulic pressure control unit is mounted near the handle, then there is sufficient mounting space, but equipment that should be visually perceived cannot be preferentially disposed

Engineering Contradiction:
Improvemounting spaceVSAvoidvisual perception
Core Design Contradiction:
Area of stationary objectVSLoss of information

Solution Approach 1:

The hydraulic pressure control unit is extracted from the handle periphery and relocated to the front fork area. This allows visually important equipment to be mounted in the handle area where it can be properly perceived by the user, while the hydraulic control unit occupies the front fork mounting space.

Inventive Principle:
Principle #2Taking out (Extraction)
