Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wired HMI equipment is used in industrial environments, then operational control capability is maintained, but equipment durability and reliability deteriorate due to harsh conditions
Solution Approach 1:
The patent replaces wired mechanical connections with wireless communication technology. The HMI system uses wireless transceivers to communicate with the PLC, eliminating physical cables that are vulnerable to damage from vibrations, contaminants, and harsh industrial conditions. This substitution maintains operational control capability while significantly improving equipment reliability in harsh environments.
Solution Approach 2:
The patent introduces wireless communication as an intermediary between the HMI interface and the control system. Instead of direct wired connections, data is transmitted through wireless signals, acting as a mediator that isolates the HMI equipment from direct exposure to harsh environmental factors while maintaining functional connectivity.
2Reliability
If rugged equipment is used to withstand harsh industrial conditions, then equipment durability improves, but device complexity and cost increase
Solution Approach 1:
Instead of using ruggedized hardware designed to withstand harsh conditions, the patent substitutes wireless communication technology that naturally isolates the HMI equipment from environmental factors. This approach achieves durability without requiring complex ruggedized components, thereby reducing overall device complexity.
3Ease of operation
If motion-controlled wireless interface is implemented, then ease of operation improves in harsh environments, but measurement precision and control accuracy may deteriorate
Solution Approach 1:
The patent incorporates feedback mechanisms where the HMI system receives motion data from the wireless controller and processes it to generate appropriate control responses. The system continuously monitors motion inputs and adjusts the graphical interface and control commands accordingly, ensuring that ease of operation does not compromise control precision. The feedback loop validates motion commands against system state before execution.
