Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing techniques are used to display digital cards, then the implementation is simple, but the security is inadequate and cards are easily counterfeited
Solution Approach 1:
The patent applies dynamics by implementing visual effects that change based on device movement. The digital card representation includes dynamic visual elements such as shimmering, glowing, or shifting effects that respond to accelerometer data, making the card appearance variable and difficult to counterfeit while maintaining a manageable interface through automated movement detection
Solution Approach 2:
The patent changes visual parameters of the digital card representation based on device movement parameters. Accelerometer data is used to modify visual effect intensity, animation speed, or effect type, creating a dynamic security feature that adapts to physical movement while keeping the implementation structured through parameter-based control
2Ease of operation
If existing techniques are used to display digital cards, then the interface is simple, but the cognitive burden on users is high due to complex authentication steps
Solution Approach 1:
The system performs self-service by automatically detecting device movement and triggering appropriate visual effects without requiring user initiation. The accelerometer continuously monitors device state and the system autonomously adjusts the card representation, eliminating the need for users to manually activate security features or perform complex authentication sequences
Solution Approach 2:
The visual effects are prepared and configured in advance through the visual asset definition data structure, which pre-defines multiple visual effect options. When device movement is detected, the system quickly switches between pre-configured effects, reducing authentication time by avoiding real-time effect generation while maintaining security through pre-planned visual variations
3Use of energy by moving object
If existing techniques are used to display digital cards, then the energy consumption is moderate, but battery life is reduced due to inefficient display updates
Solution Approach 1:
The system uses periodic action by updating visual effects only when device movement is detected through the accelerometer, rather than continuously updating the display. The accelerometer operates in a sleep-wake cycle, activating visual effect updates only during movement events, which significantly reduces overall energy consumption while maintaining security through event-driven updates
Solution Approach 2:
The patent extracts the continuous update function and replaces it with event-triggered updates based on accelerometer data. By separating the display update mechanism from continuous operation and linking it only to movement events, the system eliminates unnecessary energy consumption while preserving the security function through selective visual effect activation
