Solution Overview
Problem
Existing game boards lack the ability to accurately and uniquely identify and track multiple game pieces in real-time, especially when they are not physically touching the playing surface, and do not allow for seamless integration of RFID technology with touchscreen functionality.
Innovation Solution
A smart game board system that incorporates a radio frequency identification (RFID) localization array between a touch sensing layer and a display panel, using chip-less RFID tags and a control module with a processor and communication interface to correlate RFID data with touchscreen data for precise game piece location and identification, allowing for interactive gameplay with custom game pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID technology is integrated with touchscreen functionality, then game piece identification accuracy is improved, but device complexity increases
Solution Approach 1:
The patent combines RFID localization array and touchscreen sensing layers into a single integrated game board structure. The RFID array is positioned between the display panel and touch sensing layer, allowing both RFID reading and touch input functions to coexist in one device without requiring separate systems, thereby reducing overall device complexity while maintaining high identification accuracy
Solution Approach 2:
The game board serves multiple functions simultaneously: it provides touch input sensing, RFID game piece identification, and display output. The integrated structure allows the same hardware system to handle both traditional touchscreen interactions and RFID-based game piece tracking, eliminating the need for separate systems and reducing complexity
2Ease of operation
If multiple game pieces are tracked in real-time, then gameplay interactivity is improved, but measurement precision requirements increase
Solution Approach 1:
The patent divides the game board into multiple RFID reading zones corresponding to different game squares. Each zone can independently identify and track game pieces within its area. The control module segments the RFID signal processing to handle multiple pieces simultaneously, assigning unique identifiers to each piece and tracking their positions independently across different zones
Solution Approach 2:
The system transitions from traditional 2D touchscreen tracking to 3D spatial localization by adding vertical layering. The RFID array is positioned at a specific depth between the display panel and touch sensing layer, creating a three-dimensional detection volume that enables precise localization of game pieces in space while maintaining real-time tracking of multiple pieces
3Measurement precision
If RFID array is positioned between touch sensing layer and display panel, then game piece tracking accuracy is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent implements a nested layer structure where the RFID localization array is embedded within the existing touchscreen assembly. The RFID array is positioned between the display panel layer and the touch sensing layer, creating a nested configuration where multiple functional layers are integrated within a compact vertical profile. This nesting approach maintains precise positioning while simplifying the overall manufacturing process
4Measurement precision
If 1 mm by 1 mm accuracy is achieved, then game piece location precision is improved, but device complexity increases
Solution Approach 1:
The system employs feedback mechanisms where the control module continuously receives RFID signal strength information from the array, processes this data to determine game piece locations, and provides feedback to update the displayed game state. This feedback loop enables high precision location tracking while the automated processing reduces the need for complex manual calibration and adjustment mechanisms
