Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional virtual reality systems are used, then virtual reality functionality is achieved, but cost and complexity increase
Solution Approach 1:
The patent extracts only the essential components needed for basic virtual reality functionality: a mount with sensor to detect body movement, a flexible strip to transmit movement, and a display with controller to render virtual representations. By removing unnecessary complex components from conventional VR systems, the invention achieves the core function at lower cost and complexity.
Solution Approach 2:
The patent creates a simplified copy of virtual reality functionality using basic components. Instead of using complex motion capture systems, the invention uses a flexible strip connected to a sensor and display to replicate the essential experience of body movement translation to virtual space, achieving the same functional outcome with simpler technology.
2Reliability
If conventional virtual reality systems are used, then virtual reality functionality is achieved, but cost increases
Solution Approach 1:
The patent employs inexpensive components that can be easily manufactured and replaced: a simple mount with sensor, flexible strips, and basic display/controller assembly. These low-cost components enable the system to be manufactured affordably, making virtual reality accessible without requiring expensive conventional equipment.
Solution Approach 2:
By extracting only the essential functional elements from conventional VR systems and eliminating expensive components, the patent creates a cost-effective version that maintains core virtual reality functionality while significantly reducing manufacturing cost and accessibility barriers.
3Reliability
If conventional virtual reality systems are used, then virtual reality functionality is achieved, but adoption is delayed
Solution Approach 1:
The patent changes the parameters of cost and complexity from conventional VR systems to a simplified version. By reducing manufacturing cost and system complexity, the invention makes virtual reality technology more suitable for widespread adoption in educational, training, and entertainment fields, thereby accelerating implementation rather than delaying it.

AI summary
A system for transmitting signals between a body of a living being and a virtual reality space includes a mount and a base configured to be affixed to respective first and second bony members of the body on a distal side and a proximal side, respectively, of a joint. An elongate, flexible strip is affixed at a first end to the mount and at a second end to the base. A sensor disposed on the base is configured to generate a displacement signal indicative of displacement of the strip in response to movement of the first bony member relative to the second bony member. The system further includes a display and a controller configured to receive the displacement signal and to control movement of a virtual representation of the body on the display responsive to the displacement signal and feedback of interaction in the virtual space to the living being.
