Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the brake plate is pressed against the road surface using only friction without vibration, then the braking effect is limited due to self-locking, but adding vibration means increases device complexity
Solution Approach 1:
The patent applies mechanical vibration through a vibration generator that actively vibrates the brake plate during braking. This vibration prevents self-locking between the brake plate and road surface, allowing sustained high friction forces. The vibration is generated by an eccentric rotating mechanism driven by an electric motor, which adds dynamic motion to otherwise static friction braking.
Solution Approach 2:
The vibration generator operates periodically during the braking process, creating cyclic vibrations at specific frequencies. This periodic action maintains optimal contact conditions between the brake plate and road surface, preventing continuous self-locking while maximizing the average braking force over the braking duration.
2Reliability
If a rigid connection is used between the brake plate and vehicle, then mechanical overloading may occur, but a flexible connection reduces braking effectiveness
Solution Approach 1:
The patent uses a flexible tension element (such as a cable or belt) to connect the brake plate to the vehicle chassis. This flexible connection allows the brake plate to move independently during braking, accommodating road irregularities and preventing mechanical overloading of the connection points while maintaining sufficient tensile strength to deliver the braking force to the vehicle.
3Force
If heavy brake plates are used to increase braking effect, then braking performance improves, but vehicle stability and safety are compromised
Solution Approach 1:
The patent employs dynamic braking where the brake plate is actively vibrated during operation rather than being statically fixed. This dynamic approach allows lighter brake plate masses to achieve effective braking through vibrational energy transfer, preventing the stability issues associated with heavy static brake plates while maintaining high braking force through controlled vibration mechanisms.

AI summary
The vehicle (1) has a brake plate (3) arranged at a lower side (2), and an adjusting device (7) for moving the plate from a resting position (4) to a braking position (5) on a road surface (6). The device connects the plate with the vehicle by using a carrier (15). The device has a vibration unit for active generation of vibration at the plate on the road surface in the braking position, where frequency of the vibration lies outside of resonance frequency of the vehicle. A flexible pulling element (8) has an electrical wire for supplying electrical energy to the vibration unit.
