Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical actuators are used as reset units, then adaptability of the force curve can be changed after installation, but the space and material requirements increase significantly
Solution Approach 1:
The patent replaces electrical actuators with a purely mechanical reset unit design. The elastic element (spring or elastomer) provides the restoring force mechanically, while the adapting module mechanically adjusts the pre-tensioning of the spring to change the force curve characteristics. This mechanical substitution eliminates the need for complex electrical systems, reducing space and material requirements while maintaining adaptability.
Solution Approach 2:
The reset unit is divided into separate functional modules: an elastic element for generating restoring force, an adapting module for adjusting pre-tensioning, and optionally a damping module. This segmentation allows each component to be optimized independently and enables flexible configuration to meet different space and performance requirements.
2Adaptability or versatility
If adaptive elastic materials are used, then material properties such as elasticity can be changed by applying current or magnetic field, but the design becomes space and material intensive
Solution Approach 1:
Instead of using adaptive elastic materials that require current or magnetic fields for property changes, the patent employs conventional elastic materials combined with a mechanical adapting module. The adaptation is achieved through mechanical pre-tensioning adjustment of the spring, eliminating the need for complex electrical or magnetic systems and their associated space and material requirements.
3Adaptability or versatility
If elastic elements are replaced and new ones with desired elasticity are installed, then the restoring force can be adjusted, but the maintenance becomes costly and time-consuming
Solution Approach 1:
The reset unit is designed with segmented, modular components including the elastic element, adapting module, and damping module. This segmentation allows the adapting module to be independently adjusted without replacing the entire elastic element, significantly reducing maintenance time and cost while maintaining the desired restoring force characteristics.
Solution Approach 2:
The adapting module provides dynamic adjustability of the spring pre-tensioning, allowing the restoring force to be modified without physical replacement of components. This dynamic adjustment capability enables flexible adaptation to different application requirements while simplifying maintenance procedures.
4Adaptability or versatility
If a spring is preceded by an actuator to pretension the spring, then the restoring force can be changed, but the resource-intensive design increases costs and space requirements
Solution Approach 1:
The patent replaces the electrical actuator with a purely mechanical adapting module that adjusts spring pre-tensioning through mechanical means. This substitution eliminates the need for additional electrical components, reducing both space requirements and material costs while maintaining the ability to change the restoring force as needed.
