Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional separate production and joining processes are used for torsion damper components, then manufacturing precision and reliability can be maintained, but manufacturing cost and device complexity increase significantly

Engineering Contradiction:
Improvemanufacturing costVSAvoidjoining process complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the inner coupling surface, outer coupling surface, and membrane structure into a single integrally connected ring element. This eliminates the need for separate joining processes between these components, reducing both manufacturing cost and process complexity while maintaining the functional requirements of the torsion damper.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrally connected ring element serves multiple functions simultaneously: it provides the coupling surfaces for mounting, contains the membrane structure for torsional elasticity, and acts as the structural framework. This multi-functionality reduces the number of separate components needed, simplifying the overall device structure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If traditional separate production and joining processes are used for torsion damper components, then component reliability can be ensured, but production time and manufacturing complexity increase

Engineering Contradiction:

Solution Approach 1:

By combining multiple components into a single integrally connected ring element, the patent reduces the number of assembly steps and joining operations required during manufacturing. This streamlines the production process, reducing both production time and manufacturing complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integral connection of the ring element components is established during the initial forming process rather than requiring subsequent joining operations. This preliminary action of creating the integral structure upfront eliminates the need for time-consuming assembly and joining steps later in the manufacturing process.

Inventive Principle:

Solution Approach 1:

The patent eliminates the need for separate joining processes by integrating the components into a single piece. This removes the requirement for surface treatments and thermal forming processes that would otherwise be needed to achieve strong joints, thereby reducing manufacturing cost and complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts or eliminates the joining processes entirely from the manufacturing sequence by designing the components to be integrally connected. This removes the need for complex surface treatments and thermal forming operations that add cost and time to the manufacturing process.

Inventive Principle:
Principle #2Taking out (Extraction)

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

This design reduces production costs and complexity by enabling precise adjustment of damping and springing properties through material and geometric combinations, facilitating the use of lower elasticity materials and simplifying the manufacturing process while maintaining effective torsional force transmission.

Implementation Method 1

The membrane structure is formed from a plurality of flexible, deformable support elements which run radially and/or concentrically to an axis of symmetry of the ring element and extend along the axis of symmetry. The radially extending support elements take over the torsionally elastic transmission of rotational forces acting in the circumferential direction or about the axis of symmetry between the inner transmission body and the outer support element.

Implementation Method 2

The flexible, deformable support elements transmit the torsional forces in an elastically damping manner. The material, shape and dimensions of the support elements determine the elasticity and damping properties.
