Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If metal springs are used to apply force to counteract deformation, then the support structure provides continuous force application, but the force cannot be adapted to environmental fluctuations and material properties
Solution Approach 1:
The patent replaces static metal springs with a dynamic actuator unit that can actively adjust the applied force. The actuator unit includes a motor-driven mechanism with a movable arm that can change its position and applied force based on real-time sensor feedback about environmental conditions and artwork deformation, enabling adaptive support rather than fixed force application
Solution Approach 2:
The patent implements a feedback control system where sensors continuously monitor environmental parameters (temperature, humidity) and artwork state (deformation, position). This data is fed back to the control unit, which adjusts the actuator unit's force output accordingly. This closed-loop feedback mechanism enables the support structure to automatically adapt to changing conditions without manual intervention
2Stability of the object's composition
If the support frame is firmly connected to the artwork, then stable force application is achieved, but the force is either too large or too small in details depending on environmental conditions
Solution Approach 1:
The patent transforms the firmly connected static support into a dynamic system where the actuator unit's arm can move along the support frame. This movement capability allows the system to maintain stable connection to the artwork while dynamically adjusting the force magnitude and application point based on real-time conditions, resolving the contradiction between stability and adaptability
3Reliability
If fixed force is applied by support structures, then simple structure is maintained, but deformation cannot be prevented under fluctuating environmental conditions
Solution Approach 1:
The patent employs sensor units that continuously monitor environmental conditions (temperature, humidity) and artwork deformation. This feedback information is processed by a control unit that automatically adjusts the actuator unit's force output to prevent deformation. The feedback mechanism enables reliable deformation prevention while keeping the control logic automated rather than requiring complex mechanical adjustments
Solution Approach 2:
The patent replaces the purely mechanical spring-based force application system with an electromechanical system. The actuator unit uses motor-driven mechanisms controlled by electronic sensors and a control unit, substituting passive mechanical force application with active electromechanical control. This enables adaptive force adjustment while maintaining relatively simple hardware architecture
