Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas are used to create a three-dimensional recognition space and calculate user positions, then user immersion and interaction are enhanced, but device complexity increases
Solution Approach 1:
The patent transitions from traditional two-dimensional screen interaction to three-dimensional spatial recognition by incorporating multiple antennas that detect signals from different spatial dimensions. This enables the system to calculate user position in 3D space (x, y, z coordinates) rather than just 2D plane coordinates, creating a volumetric recognition space that enhances immersion and interaction capabilities.
Solution Approach 2:
The patent introduces signal transmission and reception as an intermediary mechanism between the user and the exercise content. Multiple antennas receive signals from portable devices worn by users, and the processor calculates positions based on these signals. This intermediary signal-based approach enables indirect detection of user position and movement, allowing for complex spatial tracking without direct mechanical or optical contact.
2Adaptability or versatility
If exercise content is adjusted in real-time based on user position and movement, then user experience is improved, but processing requirements and energy consumption increase
Solution Approach 1:
The patent pre-defines multiple exercise content options and their corresponding display parameters before runtime. Based on the calculated user position and movement state, the system selects from these pre-prepared content variants rather than generating content in real-time. This preliminary preparation reduces the computational burden during actual exercise sessions, lowering energy consumption while maintaining adaptive content delivery.
Solution Approach 2:
The system automatically detects user position and movement through the antenna signals and autonomously adjusts the exercise content and display parameters without requiring manual input or complex real-time processing. The processor continuously monitors signal changes and self-adjusts the displayed content based on predefined rules, reducing the need for energy-intensive real-time analysis and user intervention.
3Adaptability or versatility
If a three-dimensional recognition space is defined based on signal transmission, then spatial awareness and group exercise capabilities are enhanced, but measurement precision requirements increase
Solution Approach 1:
The patent divides the recognition space into multiple zones or regions (e.g., front zone, side zones, rear zone) with different spatial characteristics. Instead of requiring continuous high-precision position tracking throughout the entire space, the system segments the area and assigns different precision requirements to different zones. This segmentation allows for coarser precision in less critical areas while maintaining adequate spatial awareness for group exercise activities.
Solution Approach 2:
The system dynamically adjusts measurement precision parameters based on the user's position and activity context. When users are in positions requiring high precision (e.g., near the center or performing specific exercises), the system increases measurement accuracy. In other positions or during less critical phases, it reduces precision requirements, thereby lowering the overall measurement burden while maintaining sufficient spatial awareness for group exercises.
