Bicycle Disc Brake Caliper Adjustable Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc brake caliper systems for bicycles lack a robust and adjustable mechanism for securely attaching to the bicycle frame, particularly in accommodating different sizes of brake disc rotors, which can affect braking performance and ease of installation.
Innovation Solution
A disc brake caliper design featuring a base member with adjustable threaded holes and bolts that allow for secure attachment to the bicycle frame, enabling the caliper to be positioned relative to the brake disc rotor in various orientations and diameters, ensuring proper alignment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed attachment mechanism is used, then the structure is simple, but it cannot accommodate different sizes of brake disc rotors
Solution Approach 1:
The attachment mechanism incorporates adjustable threaded holes that can be repositioned along the base member, allowing the caliper to be mounted at different positions to accommodate various brake disc rotor sizes. This dynamic adjustability resolves the contradiction by enabling versatility without requiring multiple fixed-configuration components.
Solution Approach 2:
The base member is divided into multiple sections with threaded holes at different positions, allowing selective attachment points. This segmentation enables the attachment mechanism to adapt to different rotor sizes while maintaining a relatively simple overall structure, as each segment serves a specific positioning function.
2Adaptability or versatility
If adjustable threaded holes are provided, then adaptability to different rotor sizes is improved, but manufacturing complexity increases
Solution Approach 1:
The base member is designed as a universal component with multiple threaded holes that can serve different positioning functions. This multi-functionality allows a single manufactured part to accommodate various rotor sizes, improving adaptability while avoiding the need to manufacture multiple specialized components, thereby maintaining ease of manufacture.
3Ease of operation
If multiple threaded holes are provided on the attachment surface, then positioning flexibility is improved, but assembly complexity increases
Solution Approach 1:
The attachment surface provides multiple threaded holes at different positions and orientations, allowing the installer to dynamically select the most appropriate attachment configuration based on the specific brake disc rotor being installed. This dynamic positioning flexibility simplifies the installation process for different rotor types while maintaining a manageable attachment surface design.

AI summary
A disc brake caliper for applying a braking force on a brake disc rotor configured to be rotatable about a rotational axis. The disc brake caliper comprises an attachment surface and a first threaded hole. The attachment surface is configured to face a pipe portion of a bicycle frame in a state where the disc brake caliper is coupled to the bicycle frame. A first thread bolt is to be inserted in the first threaded hole so as to couple the disc brake caliper to one of the bicycle frame and a base member attached to the bicycle frame, the first threaded hole being provided on the attachment surface.
