Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake mechanisms for electric vehicles, such as disk and drum brake mechanisms, exhibit poor braking performance.
Innovation Solution
A brake mechanism with an adjustably positioned brake pad that can switch between contact and non-contact positions with the tire, utilizing an elastic member and drive part to ensure effective frictional braking, allowing for adaptable use with different tire diameters and models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional disk or drum brake mechanisms are used, then the brake system structure is established, but the braking performance is poor
Solution Approach 1:
Instead of having the brake pad contact a rotating disc or drum (traditional approach), this invention inverts the approach by having the brake pad directly contact the stationary tire surface. The brake assembly rotates with the wheel while the brake pad remains stationary relative to the vehicle body, creating friction directly on the tire to achieve superior braking performance.
Solution Approach 2:
The brake pad is extracted from the traditional rotating brake disc/drum system and repositioned to contact the tire surface directly. This separation allows the brake pad to be positioned optimally for direct tire contact while the brake assembly rotates independently with the wheel.
2Adaptability or versatility
If the brake pad position is fixed, then the structure is simple, but it cannot adapt to different tire diameters and models
Solution Approach 1:
The brake pad position is made adjustable rather than fixed, allowing it to be dynamically repositioned to accommodate different tire diameters and models. The adjustable mechanism enables the brake pad to maintain optimal contact with various tire surfaces while keeping the overall brake assembly structure relatively simple.
3Use of energy by moving object
If the brake pad contacts the tire at all positions, then continuous braking is possible, but energy is wasted during non-braking periods
Solution Approach 1:
The brake pad makes contact with the tire periodically only when braking is required, rather than maintaining continuous contact. The adjustable positioning mechanism allows the brake pad to be moved into contact with the tire surface during braking and retracted during normal operation, achieving energy efficiency while maintaining simple braking control through the drive part actuation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The brake mechanism provides improved braking performance by ensuring direct contact with the tire surface, generating a greater braking force and being adaptable to various tire sizes, with a simple, low-cost design suitable for karting and balance vehicles.
Implementation Method 1
