Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized control panel is used in an alarm system, then the system can be controlled from a single location, but the system becomes vulnerable to total failure if the control panel malfunctions and requires complex wired connections that increase installation costs
Solution Approach 1:
The patent divides the centralized control panel into multiple distributed event devices, each capable of independent operation. Each device contains local processing logic and can function autonomously, eliminating the single point of failure inherent in centralized systems. The segmentation of control functions across multiple devices directly addresses the reliability-complexity contradiction by distributing risk while maintaining manageable individual device complexity.
Solution Approach 2:
The system transitions from a centralized control architecture to a distributed architecture, fundamentally changing the system's organizational parameter. This architectural parameter change enables the system to achieve higher reliability through redundancy while the individual device complexity remains low, as each distributed device is simpler than the centralized panel it replaces.
2Reliability
If wired connections are used to connect event devices to the control panel, then reliable communication can be achieved, but installation becomes difficult and expensive requiring significant material and labor
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. Event devices communicate with each other and with monitoring systems via wireless signals, eliminating the need for physical wiring infrastructure. This substitution maintains communication reliability through protocol design and redundancy while dramatically improving installation ease by removing the complex wiring requirement.
3Ease of operation
If a centralized control panel is used, then system control is centralized, but modifications to the system become difficult and expensive
Solution Approach 1:
By segmenting the control function into multiple independent event devices, the system gains adaptability. Each device can be independently configured, added, removed, or modified without affecting the entire system. This segmentation directly improves adaptability while maintaining ease of operation through standardized device interfaces and centralized monitoring capabilities.
4Stability of the object's composition
If wired connections are used throughout the facility, then stable communication can be maintained, but installation and modification require high material costs and labor
Solution Approach 1:
The patent substitutes wireless communication for wired connections, eliminating the physical materials (cables, connectors, conduits) required for wired installations. Communication stability is maintained through error correction protocols, signal redundancy, and mesh networking capabilities inherent in the wireless event device system, while the quantity of material required drops to nearly zero.
