Problem
Current equipment management systems in manufacturing plants face challenges in ensuring that only intended information is detected and transmitted securely via wireless communication, as they lack effective control mechanisms to prevent unintended information from being detected and leaked, which can lead to contract violations and data security breaches.
Innovation Solution
An equipment management system with a field manager and adaptive system control units that include information detection, detected information control, data propagation adjustment, and equipment control mechanisms to ensure only intended information is acquired and transmitted through appropriate communication paths, preventing unintended information from being detected or leaked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication is used for equipment management, then flexibility in equipment arrangement and production line construction is improved, but communication interference and system failures occur due to frequency band conflicts
Solution Approach 1:
The patent introduces a frequency coordination mechanism as an intermediary that manages and coordinates frequency band usage across multiple wireless communication systems. This mediator prevents direct conflicts by allocating frequencies systematically, thereby maintaining both wireless flexibility and communication reliability.
Solution Approach 2:
The patent creates a universal frequency management system that serves multiple wireless communication systems simultaneously. This multi-functional coordination mechanism handles frequency allocation, interference detection, and conflict resolution across diverse equipment, enabling universal wireless management while preventing interference.
2Ease of operation
If wireless communication systems are introduced individually per equipment, then equipment management flexibility is improved, but communication resources cannot be distributed optimally and interference occurs
Solution Approach 1:
The patent merges individual equipment-level wireless management into a unified system-wide coordination mechanism. By combining frequency management functions across all equipment, the system optimizes communication resource distribution while maintaining individual equipment flexibility through centralized coordination.
Solution Approach 2:
The patent implements a feedback mechanism where the frequency coordination system continuously monitors communication quality and equipment status, then adjusts frequency allocations dynamically. This feedback loop ensures optimal resource distribution while preventing interference, balancing individual equipment needs with overall system efficiency.
3Productivity
If the same frequency band is used between wireless management systems, then frequency resource utilization is improved, but communication interference and system failures are caused
Solution Approach 1:
The patent dynamically changes frequency parameters based on system conditions, equipment requirements, and interference levels. By adjusting frequency allocations, power levels, and timing parameters, the system maximizes frequency resource utilization while avoiding harmful interference through continuous parameter optimization.
Solution Approach 2:
The patent transitions from static frequency assignment to dynamic frequency coordination. The system continuously adapts frequency allocations based on real-time conditions, allowing multiple systems to share frequency bands safely by changing parameters dynamically rather than using fixed assignments, thereby improving utilization while preventing interference.
