Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

By integrating the fluid tube and electrical line into a base board, the patent consolidates multiple components into a compact unified structure. This merging enables better space utilization by eliminating the need for separate routing paths and allowing more efficient use of the motorcycle's internal space

Inventive Principle:

Core Design Contradiction:

Ease of manufactureVSLength of moving object

Solution Approach 1:

The base board serves as an intermediary that optimizes the routing of the fluid tube. By integrating the tube into the base board structure, the flow distance is minimized compared to external routing, while the tube remains accessible for connection purposes

Inventive Principle:

Principle #24Intermediary (Mediator)
