Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake systems for bicycles lack efficient adjustment mechanisms for the initial position and sensitivity of brake levers, and require time-consuming maintenance procedures for the caliper assembly.
Innovation Solution
The brake system incorporates an improved master cylinder assembly with adjustable initial position and sensitivity settings, and an enhanced caliper assembly with a tool-assisted maintenance system for easy removal of air and fluid management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the brake lever position and sensitivity are fixed, then the brake system structure is simple, but the operator cannot adjust for performance and preference/comfort
Solution Approach 1:
The master cylinder assembly incorporates adjustable components that allow the operator to dynamically change the initial position of the piston and the sensitivity of the braking function. The brake lever position can be adjusted along its arc of motion, and the piston's initial position can be modified, transforming a static system into a dynamic one that adapts to different operating preferences and conditions.
2Productivity
If the caliper assembly requires traditional maintenance procedures, then the system structure is simple, but maintenance is time-consuming and inefficient
Solution Approach 1:
The caliper assembly is designed with pre-configured maintenance features, including a tool that can be inserted through a access port to directly engage with internal components. The design anticipates maintenance needs by providing ready-access pathways and engagement points, allowing maintenance personnel to perform bleeding, fluid replacement, and inspection operations without disassembling the entire assembly, thus significantly reducing maintenance time.
3Ease of operation
If air removal from the caliper body requires disassembly, then the system structure is simple, but the maintenance process is complex and time-consuming
Solution Approach 1:
The design extracts the air removal function from the complex internal structure of the caliper by providing a dedicated access port and tool configuration. The tool can be inserted through this port to reach and operate on air bubbles trapped in the fluid passages, effectively separating the air removal operation from the need to disassemble the caliper housing, thereby simplifying the maintenance procedure while maintaining system integrity.
