Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle brake systems lack an effective mechanism to prevent wheel lockup during sudden braking, which can lead to loss of control and safety issues.
Innovation Solution
An anti-lock brake device comprising an oil pressure tank, valve, and movable component, where the movable component slides between initial and depressurized positions to create a depressurized volume, reducing oil pressure and loosening the bicycle caliper to prevent wheel lockup, utilizing a magnetic force generator and elastic components to control the valve and oil flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the brake system uses a simple caliper design to reduce device complexity, then the ease of manufacture is improved, but the ability to prevent wheel lockup during sudden braking is worsened
Solution Approach 1:
The brake system is segmented into multiple functional components: a movable component with connecting channel, a valve mechanism, and an oil pressure tank with specific volume chambers. This segmentation allows each component to perform its specific function independently, achieving anti-lock braking capability through coordinated operation of simple individual parts
Solution Approach 2:
The oil pressure tank pre-stores oil in its accommodation space, and the movable component is pre-positioned to control oil flow. When sudden braking occurs, the system can immediately respond by moving the movable component to adjust oil pressure, preventing wheel lockup without requiring complex real-time control systems
2Reliability
If the brake system uses a complex valve and movable component mechanism to prevent wheel lockup, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The valve mechanism is merged with the movable component, which is itself integrated into the oil pressure tank structure. The connecting channel of the movable component serves dual purposes: it connects oil inlet and outlet channels while also acting as part of the volume control mechanism. This merging reduces the number of separate components and simplifies the overall structure
Solution Approach 2:
The movable component performs multiple functions: it controls oil flow through its connecting channel, adjusts oil pressure by changing effective volume, and acts as a mechanical linkage between the brake lever and valve. This multi-functionality reduces the need for additional specialized components, maintaining simplicity while achieving reliable anti-lock braking

AI summary
The disclosure provides an anti-lock brake device including an oil pressure tank, a valve, and a movable component. The oil pressure tank has an accommodation space, an oil inlet channel, and an oil outlet channel connected to the accommodation space. The valve is slidably located in the oil inlet channel and for sealing or opening an oil inlet of the oil inlet channel. The movable component is located in the accommodation space and has a connecting channel corresponding to the oil inlet and an oil outlet of the oil outlet channel. When the movable component is slid to a depressurized position, the movable component is moved away from the valve for sealing the oil inlet, a first volume is produced between the connecting channel and the oil inlet, and a second volume, smaller than the first volume, is removed from between the connecting channel and the oil outlet.
