Building Net Displacement System for Automated Sports Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports practice buildings require manual intervention and assembly/disassembly of sports equipment, such as nets and uprights, and often necessitate holes in the floor for upright installation, which is inefficient and space-consuming.
Innovation Solution
A building with a net displacement system where net uprights are movable relative to the roof, using electromagnetic attraction for holding the net in the use position, and an electric motor to move the uprights between use and standby positions, allowing remote control via smartphone app, eliminating the need for manual intervention and floor holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual intervention is used to install and remove net equipment, then the system is simple and cost-effective, but the installation process is time-consuming and labor-intensive
Solution Approach 1:
The net system performs self-service by automatically deploying and retracting the net through electromagnetic attraction to the roof, eliminating the need for manual installation and removal by users. The system serves itself by using the building's existing electromagnetic infrastructure to position the net uprights and maintain tension.
Solution Approach 2:
The patent replaces manual mechanical assembly with electromagnetic attraction. Instead of users physically installing net posts into floor holes, the system uses electromagnetic forces to attract and hold the net uprights against the roof, converting mechanical manual labor into automated electromagnetic action.
2Reliability
If net uprights are fixed to the floor with holes, then the net is stable and secure, but the floor structure is damaged and space is consumed
Solution Approach 1:
The patent inverts the traditional support approach by moving the net uprights from floor-based support to roof-based support. Instead of anchoring net posts into the floor, the uprights are positioned against and held to the roof through electromagnetic attraction, completely reversing the support direction and eliminating floor modifications.
Solution Approach 2:
The patent extracts the support function from the floor structure and relocates it to the roof structure. By removing the requirement for floor holes and anchoring, the system takes out the invasive element from the floor and places the support mechanism on the roof where it does not consume floor space or damage the floor structure.
3Speed
If net equipment is stored separately, then quick deployment is possible, but significant storage space is required
Solution Approach 1:
The patent merges the storage function with the operational function by integrating the net uprights and net into the building's roof structure. When not in use, the net is retracted and stored within the building footprint, combining storage and deployment into a single integrated system that eliminates separate storage areas.
Solution Approach 2:
The net system employs nesting by placing the net and uprights within the building's vertical space. The net can be stored in a compact retracted position within the building envelope, nesting the equipment inside the existing structure rather than requiring external storage space.

AI summary
A building (100) comprising on the one hand a building structure having a roof which extends in a horizontal plane P and which has a plurality of cross members (130a, 130b) arranged parallel to each other and on the other hand a system for moving a net (210) stretched between two net uprights (202) allowing the net to be held (i) in a waiting position in which the net (210) is positioned against the roof and (ii) in a use position in which the net (210) is perpendicular to the roof the movement system comprising means for holding the net in the waiting position positioned on the underside of the roof and means for holding the net in the use position positioned on the underside of the roof.
