Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional tracking devices (GPS, wristbands, clip-ons) are used, then tracking is possible, but measurement precision is insufficient for precise three-dimensional movement tracking
Solution Approach 1:
The device segments the tracking function into multiple independent resonators (at least three of them) positioned at different locations. Each resonator independently detects movement in its local field, and the processor integrates these segmented measurements to calculate precise three-dimensional position, orientation, and movement trajectory, achieving high precision without requiring a single complex sensor system
Solution Approach 2:
The patent introduces magnetic fields as an intermediary medium between the resonators and the conductive wire. The resonators generate magnetic fields that interact with the conductive wire, and this magnetic field interaction serves as the mediator for detecting movement. This intermediary approach enables non-contact, high-precision measurement of three-dimensional movement without mechanical contact
2Adaptability or versatility
If conventional equipment is used, then tracking is available, but adaptability to different applications and dimensions is limited
Solution Approach 1:
The device achieves universality by designing a system where at least three resonators can be configured in different spatial arrangements and orientations. The same basic resonator-wire mechanism can track movement in various dimensions (x, y, z axes) and apply to different scenarios such as exercise form analysis, industrial assembly monitoring, robotic motion tracking, and construction site supervision, making it multi-functional across diverse applications
Solution Approach 2:
The patent transitions from conventional one-dimensional or two-dimensional tracking to three-dimensional tracking by adding resonators in multiple spatial dimensions. The system calculates position, orientation, and movement trajectory in three-dimensional space, enabling comprehensive tracking that adapts to various application requirements whether linear movement, rotational movement, or complex three-dimensional motion needs are present
