Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional treadmill gait training is used, then repeated gait training can be provided, but it is not interesting enough for children and different from the real walking environment
Solution Approach 1:
The patent projects virtual images of real walking environments (parks, streets, schools) onto the ground surface, creating a copy of the real environment that children can interact with. This allows children to practice gait training in a familiar, engaging context while maintaining the repetitive nature of treadmill training.
Solution Approach 2:
The patent adds a vertical dimension by projecting images onto the ground surface from above, creating a three-dimensional visual experience. The virtual environment is layered over the physical treadmill surface, combining the repetitive treadmill motion with the engaging visual of real-world environments.
2Reliability
If robot-assisted gait training is used, then gait training can be provided with physical guidance, but it involves expensive equipment and applications are limited by the physical condition of a child
Solution Approach 1:
Instead of using expensive robotic equipment, the patent creates a virtual copy of the training environment projected onto the ground. This virtual environment provides physical guidance through projected footprints and environmental cues without requiring complex robotic hardware, making the system more accessible and cost-effective.
Solution Approach 2:
The patent replaces the mechanical robotic system with an optical projection system. Instead of using robots to physically guide children through gait training, the system uses projected visual cues (footprints, environmental images) to guide children, substituting mechanical guidance with visual information projection.
3Ease of operation
If existing virtual reality technology is used for sport activities, then engaging content can be provided, but there are insufficient exercise systems capable of real-time interaction with the real environment
Solution Approach 1:
The patent incorporates real-time feedback by detecting the child's position and movement during gait training and dynamically adjusting the projected virtual environment. The system responds to the child's actions by updating the projected images, creating an interactive experience that adapts to the child's progress and engagement level.
