Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple tokens modulate fields in complex ways on a touchscreen surface, then the functionality and interaction capabilities are enhanced, but the accuracy of identifying and differentiating individual tokens deteriorates
Solution Approach 1:
The patent segments the field modulation approach by assigning unique modulation codes to different tokens, allowing the system to distinguish between multiple tokens even when they modulate fields in complex ways. Each token's unique code acts as a signature that enables precise identification and differentiation, resolving the contradiction between enhanced interaction capabilities and accurate token identification.
2Measurement precision
If circuitry decodes fields modulated according to unique modulation codes, then token differentiation precision is improved, but device complexity increases
Solution Approach 1:
The decode circuitry is designed with multi-functionality to handle various modulation codes and token types through a unified decoding architecture. This universal approach allows the system to achieve high token differentiation precision without proportionally increasing device complexity, as the same circuitry can decode multiple different modulation schemes.
3Quantity of substance
If tokens are positioned and differentiated on a touchscreen surface, then the quantity of distinguishable objects increases, but the difficulty of detecting and measuring their individual fields increases
Solution Approach 1:
The patent applies local quality by assigning unique modulation codes to specific tokens based on their positions or identities on the touchscreen surface. This allows the detection system to focus on decoding the specific modulation pattern of each token rather than attempting to detect and differentiate all tokens simultaneously through complex field analysis, thereby reducing the overall difficulty of detection and measurement while increasing the number of distinguishable tokens.
