Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wireless LAN communication is used for cost-effective implementation, then communication cost is reduced, but communication stability deteriorates due to disconnections and delays from movement out of access point coverage or shadow areas
Solution Approach 1:
The patent combines multiple wireless communication technologies (wireless LAN and local 5G) into a single communication device, enabling the system to leverage both technologies' strengths while mitigating their individual weaknesses through unified management and selection mechanisms
Solution Approach 2:
The patent dynamically changes communication parameters by selecting different wireless technologies based on real-time communication qualities, environmental conditions, and user-defined priorities, allowing the system to adapt to varying operational contexts and maintain stable communication
2Device complexity
If a fixed priority scheme is used for selecting wireless communication technologies, then device complexity is reduced, but adaptability deteriorates because priorities cannot change depending on use environments
Solution Approach 1:
The patent implements a dynamic priority mechanism where the selection unit can change communication technology priorities in real-time based on environmental conditions, communication qualities, and user-defined criteria, transforming a static selection system into an adaptive one that responds to changing operational contexts
Solution Approach 2:
The patent incorporates feedback mechanisms where communication qualities and environmental information are continuously monitored and fed back to the selection unit, which then adjusts technology selection priorities accordingly, creating a closed-loop system that learns and adapts to optimal performance
3Speed
If real-time information exchange is implemented between control device and auto-moving truck, then communication responsiveness is improved, but communication requirements increase due to need for continuous position and instruction data
Solution Approach 1:
The patent extracts and prioritizes only the essential communication elements needed for real-time operation, separating critical position and instruction data from non-essential information, thereby achieving responsive communication while minimizing data transmission overhead through selective data exchange
