Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a great number of presentation devices are used to complete a large-scale stage performance, then the presentation effect is improved, but the control circuit complexity increases and the fault-tolerant rate decreases
Solution Approach 1:
The patent segments the control system into multiple control periods, with each control period independently controlling specific presentation devices. The mapping relation file divides control instructions by device type and control period, allowing complex presentations to be broken down into manageable segments that can be controlled and monitored independently, thus reducing overall control circuit complexity while maintaining comprehensive presentation capability
Solution Approach 2:
The patent implements preliminary action by pre-generating the mapping relation file that contains all control instructions, frequencies, and device mappings before the performance begins. This advance preparation organizes the control logic in advance, reducing real-time control complexity and allowing the system to execute pre-planned sequences rather than making complex decisions during performance
2Ease of operation
If operational staffs synchronously control performance through wireless communication devices, then the presentation effect is improved, but the delay time increases and the fault-tolerant rate decreases
Solution Approach 1:
The patent introduces an intermediary mechanism - the mapping relation file - that acts as a pre-established control blueprint between the control system and presentation devices. Instead of real-time wireless communication for each control decision, the system uses this intermediary file that contains all necessary control instructions, frequencies, and device mappings, eliminating the need for continuous wireless communication during performance and reducing delay time
Solution Approach 2:
The control instructions and device mappings are prepared in advance in the mapping relation file, allowing the system to execute pre-planned synchronous control sequences without real-time communication delays. The preliminary preparation of control logic eliminates the need for time-consuming wireless communication during the actual performance
3Reliability
If delay time and emergency processing time are reserved for each part, then the presentation effect is ensured, but the operational requirements increase and the fault-tolerant rate decreases
Solution Approach 1:
The patent embeds delay times and emergency processing times directly into the mapping relation file as pre-calculated parameters for each control instruction. This preliminary calculation of timing parameters eliminates the need for operational staff to manually reserve and manage delay times during performance, reducing operational complexity while ensuring reliable timing for each device activation
Solution Approach 2:
The system performs self-service by automatically managing delay times and emergency processing times through the pre-configured mapping relation file. The control device autonomously retrieves and executes the pre-calculated timing parameters without requiring operational staff to manually intervene or make real-time timing decisions, reducing operational requirements while maintaining reliability
4Device complexity
If the control system uses a simple structure, then the device complexity is reduced, but the measurement precision of device synchronization decreases
Solution Approach 1:
The patent achieves precise synchronization through parameter changes by incorporating frequency specifications for each control instruction in the mapping relation file. By varying the frequency parameters of control signals according to the specific requirements of each presentation device and control period, the system achieves high synchronization precision without requiring complex hardware structures, relying instead on intelligent parameter management
