Solution Overview
Problem
The lack of available badminton courts restricts individuals from playing the sport due to the large court size requirements.
Innovation Solution
A head-mounted device-based system that displays a virtual badminton court and ball, determining user posture and movement trajectories to simulate the game in a small environment, allowing users to play by adjusting their position and performing hitting actions, thereby enlarging their movement trajectory to match the virtual court dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full-sized badminton court is used, then the game experience is authentic, but the space requirement is large
Solution Approach 1:
The patent creates a virtual copy of the badminton court using VR technology. The virtual court replicates the dimensions, markings, and playing characteristics of a real court, allowing users to experience authentic badminton gameplay in a condensed physical space. The virtual court is rendered with accurate boundary lines, service areas, and net positioning to maintain game authenticity.
Solution Approach 2:
The patent transitions from physical space to virtual space by rendering the court in a digital dimension. Users wear VR headsets to enter a virtual environment where the court exists as a computer-generated image, allowing full-sized court experience without requiring full-sized physical space. The system uses stereoscopic rendering to create depth perception and spatial awareness within the virtual dimension.
2Area of stationary object
If VR technology is used to create virtual court, then space requirement is reduced, but device complexity increases
Solution Approach 1:
The patent designs the VR system to serve multiple functions: it renders the virtual court environment, tracks user movement and racket position, calculates ball physics and trajectories, and provides haptic feedback. By consolidating these functions into an integrated system, the patent reduces overall complexity compared to separate systems for each function. The system can adapt to different court types and game modes through software configuration rather than hardware changes.
