Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual visual alignment method is used to identify display module positions, then the alignment process can be completed with simple equipment, but the positioning accuracy deteriorates when modules are spaced apart and user convenience deteriorates due to manual intervention requirement
Solution Approach 1:
The patent replaces the manual visual alignment method (mechanical/human operation) with a wireless communication-based automated positioning system. The electronic apparatus uses communication interfaces to wirelessly exchange position information and coordinate data with display modules, eliminating the need for manual visual checking and alignment operations while improving positioning accuracy through automated coordinate calculation and comparison.
2Extent of automation
If manual visual alignment method is used to identify display module positions, then the system complexity remains low, but the alignment automation level deteriorates
Solution Approach 1:
The patent implements self-service automation where the electronic apparatus and display modules automatically perform position identification through wireless communication. The system autonomously exchanges position information, calculates coordinate values, compares positions, and determines arrangement configurations without requiring external manual intervention, thereby achieving high alignment automation while managing system complexity through standardized communication protocols.
3Productivity
If wireless communication method is implemented to identify display module positions automatically, then alignment automation is improved, but device complexity increases due to communication interfaces and processing requirements
Solution Approach 1:
The patent applies universality by implementing a standardized wireless communication interface that serves multiple functions: position information exchange, coordinate data transmission, arrangement configuration communication, and alignment status reporting. This multi-functional communication system improves alignment efficiency while managing complexity by using a single versatile interface rather than separate dedicated systems for each function.
