Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireless communication setup procedures (Wi-Fi Direct, Bluetooth) are used, then reliable connection establishment is achieved, but the setup process becomes complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-storing essential connection information (device identifiers, security credentials, configuration parameters) in the touch panel device before the actual wireless connection is needed. When a user touches the panel, this pre-stored information is immediately retrieved and used to establish the wireless connection, eliminating the need for real-time device discovery, negotiation, and configuration steps that would otherwise consume time.
Solution Approach 2:
The patent extracts only the essential information needed for wireless connection establishment from the complete setup procedure. Instead of performing full device discovery, GO negotiation, and security configuration sequences, the system extracts and utilizes only the critical parameters (device identifiers, security credentials) that were previously stored in the touch panel, thereby simplifying the setup process while maintaining connection reliability.
2Loss of information
If traditional wireless communication setup procedures are used, then comprehensive device information exchange is achieved, but the number of steps increases
Solution Approach 1:
The patent applies preliminary action by pre-storing comprehensive device information (identifiers, security credentials, configuration parameters) in the touch panel device before the wireless connection is established. This allows all necessary information to be immediately available when the user performs the touch operation, eliminating the need for multiple sequential information exchange steps during the setup process.
Solution Approach 2:
The patent merges multiple information exchange operations into a single touch-based information transfer. Instead of separately performing device discovery, information exchange, and connection establishment steps, the system combines these operations by retrieving pre-stored information through the touch panel interface and using it to directly establish the wireless connection, thereby reducing the number of steps while maintaining information completeness.
3Ease of operation
If NFC technology is used for wireless communication, then contactless information exchange is achieved, but the device size increases due to additional components
Solution Approach 1:
The patent applies universality by making the touch panel serve multiple functions: it acts as both the user interface for touch input and as the communication medium for wireless connection establishment. The existing touch panel electrodes and controller are repurposed to transmit and receive communication signals, eliminating the need for separate NFC hardware components while maintaining contactless communication capability.
Solution Approach 2:
The patent creates a functional copy of NFC capabilities using the existing touch panel infrastructure. Instead of implementing actual NFC hardware with inductive card readers, the system copies the contactless information exchange function by using capacitive coupling through the touch panel electrodes, thereby achieving similar communication functionality without the volume penalty of dedicated NFC components.
