Game Court Surface Projector for Adaptable Sports Markings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game courts, especially in private residences and schools, lack sufficient space for full-sized courts, and the fixed boundaries and lines for specific sports are not adaptable for different variants or other sports, affecting training effectiveness and space utilization.
Innovation Solution
A game-court-surface projector system that projects various game boundaries and lines using a projector unit, light supply unit, and control link/control unit, allowing for easy configuration changes and use of half courts for multiple sports and training purposes without permanent markings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If boundaries and lines are painted onto the court for a specific sport, then the court is suitable for that specific sport, but the court cannot be easily adapted for other sports or variants
Solution Approach 1:
The patent uses projection technology to create virtual copies of court boundaries and lines on the court surface. Instead of physically painting lines, the system projects images that replicate the appearance of painted boundaries, allowing instant reconfiguration for different sports by changing the projected images without any physical modification to the court surface.
Solution Approach 2:
The patent implements dynamic court configurations through programmable projection systems that can change boundary lines and court markings in real-time. The system allows dynamic adjustment of court dimensions, boundary positions, and markings to accommodate different sports and game variants, transforming a static painted court into a dynamically reconfigurable surface.
2Manufacturing precision
If a full-sized court is maintained for official games, then the court meets official dimensions, but sufficient clear space is not available in private residences and schools
Solution Approach 1:
The patent utilizes the vertical dimension by mounting projection devices overhead (on ceilings, walls, or portable structures) to project court boundaries onto the floor plane. This dimensional approach allows the creation of full-sized court markings in spaces that would otherwise be insufficient, effectively using vertical space to achieve horizontal court configurations.
Solution Approach 2:
The patent creates multi-functional court spaces where the same physical area can serve multiple sports and purposes through programmable projection. A single space can be configured for basketball, volleyball, badminton, or custom training drills by changing the projected boundaries and markings, maximizing the utility of limited space in residences and schools.
3Adaptability or versatility
If boundaries and lines are fixed for one sport, then the court is optimized for that sport, but the placement is not correct for other variants and sports
Solution Approach 1:
The patent employs parameter changes in the projected images to accommodate different sports and variants. The system modifies parameters such as boundary line positions, court dimensions, marking styles, and zone definitions through software control, allowing the same physical court to display accurate configurations for professional basketball, high school basketball, volleyball, or custom training scenarios.
