Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mechanical disc brake devices are used, then the braking function is provided, but the brake pads press unevenly against the friction surface causing deformation of the backing plate
Solution Approach 1:
The brake device incorporates adjustable screws that allow dynamic adjustment of the brake pad angles and clamping angles. This enables the system to adapt and maintain optimal parallelism between the brake pads and brake disc, preventing uneven pressure distribution and backing plate deformation that occur in conventional fixed designs.
Solution Approach 2:
The invention changes the geometric parameters of the brake pad assembly through adjustable screws and flat bolts. By modifying the angles of the brake pads and clamping angles, the system maintains consistent parallelism and uniform contact pressure between the pads and disc, resolving the uneven pressure issue in conventional brakes.
2Duration of action of moving object
If brake pads are used for prolonged periods, then braking function continues, but deformation becomes noticeable leading to reduced pressure and braking force
Solution Approach 1:
The adjustable parallelism mechanism allows for preliminary adjustment of the brake pad angles and positions before deformation becomes problematic. By maintaining proper parallelism through the adjustable screws and flat bolts, the system prevents the accumulation of deformation that would otherwise lead to reduced braking force over time.
Solution Approach 2:
The V-shaped springs provide automatic expansive force that helps maintain contact between the brake pads and disc. This self-service mechanism compensates for minor deformations and wear, ensuring consistent braking force throughout the service life of the brake pads.
3Manufacturing precision
If adjustable screws and flat bolts are used to adjust brake pad angles, then parallelism and contact consistency are maintained, but device complexity increases
Solution Approach 1:
The adjustment mechanism is segmented into distinct functional components: adjustable screws for angle adjustment, flat bolts for position fixation, and V-shaped springs for contact maintenance. This segmentation allows each component to perform its specific function efficiently, making the complex adjustment system manageable and maintainable.

AI summary
An adjustable parallelism brake device for brake pads includes a pivotal arm, a main body connected to the pivotal arm, a driving disc, and an attached body to which the main body is connected. The pivotal arm is connected between the main body the driving disc. The driving disc includes a flat bearing and a flat washer mounted thereto to contact the main body. A directional drive disc is located below the driving disc. Multiple adjustable screws threadedly extend through the directional drive disc, and each have a head which supports a first friction pad. The attached body includes multiple flat threaded columns, and each flat threaded column supports a second friction pad. A pin passes through the first and second friction pads and is secured to the attached body. The friction pads angle is adjusted by the adjustable screws to prevent deformation due to prolonged use in the same position.
