Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sliding friction brakes are used, then braking force is generated, but environmental pollution occurs due to abrasion products
Solution Approach 1:
The patent replaces the traditional sliding friction mechanism with a rolling friction mechanism using roller bearings. The braking element with rollers contacts the brake disc, generating braking force through rolling friction and centrifugal force instead of sliding friction, thereby eliminating harmful abrasion products while maintaining braking reliability
Solution Approach 2:
The patent changes the fundamental friction parameter from sliding friction to rolling friction. By using rollers that rotate during contact with the brake disc, the friction type changes, which eliminates the production of harmful abrasion particles while still providing effective braking force through the combination of rolling friction and centrifugal effects
2Reliability
If multiple brake discs are used, then braking effect is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple braking elements with rollers into a single integrated braking assembly that acts on one brake disc. The housing contains multiple braking elements that work together on a single disc, simplifying the overall construction compared to using multiple separate brake discs while maintaining effective braking through the combined action of rolling friction and centrifugal force
3Power
If elastic elements are added to engage with brake disc, then braking effectiveness is improved, but device complexity increases
Solution Approach 1:
The elastic elements serve multiple functions: they apply radial force to press the rollers against the brake disc for braking, and they maintain continuous contact between the braking elements and the rotating disc. This multi-functionality increases braking power without proportionally increasing complexity, as the same elastic components perform both force application and contact maintenance

AI summary
A brake device for vehicles. The brake device includes a brake disc affixed to a wheel axle and a housing with guides affixed to a support hub. At least one guided carriage and a braking element are mounted on the guides to engage the brake disc. The braking element is formed as a roller bearing enclosing the brake disc, with radially oriented elastic elements fixed to the brake disc, and distal ends are flush or free of play with the inner surface of the inner ring (6) of the roller bearing. The carriage is displaceably mounted relative to the brake disc to enable braking without sliding friction.
