Disc Brake Caliper Adapter Orientation for Multiple Rotor Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc brake caliper adapters for human-powered vehicles face challenges in accurately attaching to different disc brake rotor sizes, leading to improper orientation and potential braking inefficiencies.
Innovation Solution
The adapter features a configurable body with indicators that allow for proper orientation alignment with both first and second disc brake rotors of different outer diameters, using distinct indicators and mounting hole configurations to ensure correct attachment states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single adapter design is used for different disc brake rotor sizes, then device complexity is reduced, but manufacturing precision and reliability deteriorate due to improper orientation
Solution Approach 1:
The adapter incorporates distinct mounting hole configurations segmented by orientation - a first set of mounting holes for a first orientation and a second set of mounting holes for a second orientation. This segmentation allows the single adapter body to provide precise orientation-specific attachment points for different rotor sizes without requiring multiple adapter designs.
Solution Approach 2:
The adapter includes pre-configured mounting hole patterns that are predetermined for specific orientations. The first mounting holes are positioned for optimal attachment when the adapter is oriented in a first direction, while the second mounting holes are positioned for optimal attachment when oriented in a second direction. This preliminary configuration of mounting holes ensures proper orientation is achieved before the brake caliper is installed.
2Adaptability or versatility
If mounting holes are positioned for multiple orientations, then adaptability to different rotor sizes is improved, but device complexity increases due to multiple hole configurations
Solution Approach 1:
The adapter body serves multiple functions by incorporating both first and second mounting hole configurations in a single component. The same adapter body can be used with different disc brake rotor sizes by selecting the appropriate mounting holes based on the rotor type, eliminating the need for multiple specialized adapters.
Solution Approach 2:
Different regions of the adapter body have different mounting hole configurations optimized for specific purposes. The first mounting holes are positioned and sized for optimal attachment with first-type rotors, while the second mounting holes are positioned and sized for optimal attachment with second-type rotors. This local differentiation provides specialized functionality in different parts of the same component.
3Reliability
If indicators are added to show orientation, then reliability of proper attachment is improved, but device complexity increases due to additional indicator components
Solution Approach 1:
The adapter incorporates visual indicators that change or differ in appearance based on orientation. First indicators are positioned to be visible when the adapter is in a first orientation, while second indicators are positioned to be visible when the adapter is in a second orientation. These indicators use color or visual contrast differences to clearly communicate the correct orientation to the installer, ensuring reliable attachment without complex mechanical indication mechanisms.

AI summary
An adapter body is configured to be attached to a vehicle body in each of a first orientation in which a caliper body is coupled to the vehicle body via the adapter body in a first position corresponding to a first disc brake rotor having a first outer diameter, and a second orientation in which the caliper body is coupled to the vehicle body via the adapter body in a second position corresponding to a second disc brake rotor having a second outer diameter different from the first outer diameter. The indicator is configured to indicate an correspondence between an orientation of the adapter body and at least one of the first disc brake rotor and the second disc brake rotor.
