Bicycle Disc Brake Caliper with Concealed Fluid Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc brake caliper designs for bicycles lack a streamlined attachment mechanism that simplifies the appearance and allows for adjustable positioning relative to the bicycle frame, while maintaining effective fluid connection and mounting stability.
Innovation Solution
The disc brake caliper incorporates a base member and a banjo fitting bolt that connects to a fluid hose, with a recess and attachment hole configuration allowing for adjustable positioning and a simplified appearance by hiding the banjo fitting bolt and fluid hose, utilizing a banjo fluid passage to connect the caliper fluid passage to the banjo fluid passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the banjo fitting bolt and fluid hose are exposed on the caliper, then the fluid connection is functional, but the aesthetic appeal is reduced
Solution Approach 1:
The patent extracts the banjo fitting bolt and fluid hose from the visible exterior of the caliper by providing an attachment structure on the facing surface that conceals these components. The connecting member is attached to the attachment structure in a manner that hides it from external view, thereby improving aesthetic appeal while maintaining functional fluid connection.
2Adaptability or versatility
If the caliper is fixedly mounted to the bicycle frame, then the mounting is stable, but the positioning adjustability is reduced
Solution Approach 1:
The patent applies dynamics by making the mounting system adjustable rather than fixed. The base member includes a mounting structure that allows the caliper main body to be positioned at different locations along the brake disc rotor's rotational direction, enabling adaptation to different rotor sizes while maintaining stable mounting through secure attachment mechanisms.
3Ease of manufacture
If the attachment structure is simplified, then the manufacturing is easier, but the mounting stability may be compromised
Solution Approach 1:
The patent merges multiple functions into the attachment structure: it provides both the aesthetic concealment of the banjo fitting bolt and fluid hose, and the secure mounting of the caliper to the bicycle frame. The base member integrates the mounting structure that accomplishes both positioning adjustability and stable fixation, simplifying manufacturing while maintaining strength.
