Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coil springs and connectors are used to dampen shock transmission, then shock damping performance is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The damping mechanism is merged with the friction disc itself. The damping web is integrally formed with the friction plate and hub, eliminating the need for separate coil springs, connectors, and retainers. This integration maintains shock damping functionality while significantly reducing assembly complexity and part count.
Solution Approach 2:
The friction disc structure itself provides the damping function through its resiliently deformable web. The web's elasticity enables it to dampen shock transmission between the friction plate and hub without requiring additional dedicated damping components, making the system self-sufficient.
2Reliability
If coil springs and retainers are used to dampen shock transmission, then shock damping performance is improved, but manufacturing cost increases
Solution Approach 1:
The damping web is formed as an integral part of the friction disc through a single molding process. This eliminates the need to manufacture and assemble separate damping components, reducing manufacturing steps, labor costs, and overall production expenses while maintaining effective shock damping.
Solution Approach 2:
The friction disc structure itself provides the damping function through its resiliently deformable web. The web's elasticity enables it to dampen shock transmission between the friction plate and hub without requiring additional dedicated damping components, making the system self-sufficient.
3Object-affected harmful factors
If a resiliently deformable damping web is used, then shock transmission is reduced, but torque transmission capability must be maintained
Solution Approach 1:
The damping web's material properties and geometric parameters are optimized to achieve the right balance. The web is designed with specific thickness, width, and material elasticity that allow it to be compliant enough to dampen shock during engagement while remaining rigid enough to transmit full torque during normal operation.
Solution Approach 2:
The damping web is made from a resiliently deformable material that combines elastic properties for shock absorption with sufficient strength for torque transmission. This composite material approach allows the single component to perform both shock damping and power transmission functions effectively.
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 solution provides effective shock absorption between the friction plate and hub, reducing complexity and manufacturing costs by using a mold-formed damping web that is easily integrated into the clutch assembly, enhancing torque transmission while minimizing assembly requirements.
Implementation Method 1
The damping web comprises a resiliently deformable material that limits transmission of shock between the plate and the hub
Implementation Method 2
The mold includes a void extending between and surrounding the plate lug and the hub lug. The method includes filling the void formed by the mold with a curable material so the material overlaps and encases the plate lug and the hub lug. In addition, the method includes curing the curable material in the mold to form a damping web
