Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless communication methods are supported for connection between portable terminals, then the adaptability and versatility of the terminal is improved, but the device complexity and ease of operation deteriorate due to the need for users to manually select and search for compatible devices
Solution Approach 1:
The terminal automatically performs device search and connection establishment without requiring user intervention. The controller autonomously manages the connection process by detecting nearby portable devices, determining compatibility, and establishing communication links, thereby eliminating manual selection and search operations while maintaining support for multiple wireless communication methods
Solution Approach 2:
The controller acts as an intermediary that manages the complexity of multiple communication methods internally. It handles the search, detection, and connection establishment processes across different wireless protocols (Bluetooth, WiFi, ZigBee, etc.) and presents a simplified interface to the user, shielding them from the underlying complexity while maintaining versatility
2Adaptability or versatility
If multiple wireless communication methods are supported for connection between portable terminals, then the adaptability and versatility of the terminal is improved, but the device complexity increases due to multiple communication protocols and processes
Solution Approach 1:
The terminal is designed with multi-functional communication capabilities that can operate across multiple wireless protocols (Bluetooth, WiFi, ZigBee, UWB, infrared). The controller universally manages these different communication methods through a unified connection management process, allowing the terminal to adapt to various portable devices without requiring separate complex procedures for each protocol
Solution Approach 2:
The controller autonomously manages the complexity of multiple communication protocols by automatically detecting which protocol is appropriate for each nearby device, configuring the connection parameters, and establishing communication links without user intervention. This self-service approach consolidates the complexity within the system rather than exposing it to the user
3Reliability
If traditional wired communication method is used for connection between portable terminals, then the reliability of connection is improved, but the ease of operation deteriorates due to the need to carry and manage communication cables
Solution Approach 1:
The patent replaces the mechanical cable-based communication system with wireless communication methods (Bluetooth, WiFi, ZigBee, UWB, infrared). This substitution eliminates the need for physical cables while maintaining reliable communication through robust wireless protocol stacks and automatic connection management, thereby improving ease of operation without sacrificing connection reliability
