Stadium Pitch Tray Storage for Multifunctional Venue Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for converting stadiums into multifunctional facilities are complex, expensive, and unsuitable for already built stadiums, often damaging the turf and invading the playing field, making them impractical for existing venues, especially those in urban settings.
Innovation Solution
A system using transportable trays configured in bands that can be stored in a pit outside the playing field perimeter, allowing conversion into a multifunctional infrastructure without affecting the stadium's original use, with mechanisms for automated removal and storage, including transport carriages, retractable lattice girders, and lifting systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the playing field is removed and stored outside the stadium footprint, then the stadium can be converted into multifunctional infrastructure, but it becomes impossible to apply in already existing stadiums or those in consolidated urban settings where there is no more space
Solution Approach 1:
The playing field trays are nested within the stadium's existing footprint by storing them vertically in a pit located inside the stadium boundaries. The pit acts as a vertical storage space that accommodates the trays when not in use, allowing the stadium to convert to multifunctional use without expanding beyond its original footprint.
Solution Approach 2:
The storage solution transitions from horizontal storage (outside the stadium) to vertical storage (within the stadium footprint). By utilizing the vertical dimension through a pit structure, the system accommodates the playing field trays within the existing stadium boundaries, enabling multifunctional conversion without requiring additional land area.
2Adaptability or versatility
If the playing field is removed by means of modules with 90° joints, then it can be stored and the stadium converted, but the joints are not technically well-resolved and result in many functional and maintenance problems
Solution Approach 1:
The playing field is divided into modular trays that can be individually removed, transported, and stored. Each tray is a self-contained unit with standardized connection interfaces, allowing for easy assembly and disassembly without complex 90° joints. The segmentation enables flexible configuration and simplifies maintenance by allowing individual tray replacement.
3Adaptability or versatility
If the playing field is stored outside the playing field perimeter, then the stadium can be converted into multifunctional infrastructure, but the solution invades the playing field and makes it too expensive to care for and treat the turf
Solution Approach 1:
The playing field trays are extracted from the permanent stadium structure and stored in a dedicated pit area within the stadium footprint. This separation allows the turf to be removed from the playing surface when not in use, enabling multifunctional events while the turf is stored and maintained in a controlled environment, reducing maintenance costs and complexity.

AI summary
A system for reversibly converting stadiums into multifunctional infrastructure by removing the pitch and storing it in a pit (6), the pitch having a set of trays (1) having a total length equal to the pitch in a longitudinal direction of the pit, which are moveable, self-supporting and have layers of soil, irrigation and turf; a set of transport trolleys (2) for lifting and moving each tray (1) from its position on the pitch to the pit (6); a set of retractable trellises (5) that can be unfolded on the pit (6), for the entry of each tray (1) from above the pit; an elevator system (8) inside the pit (6) to move each tray to its final position, in storage, or on the pitch; and a storage system (7) for storing each tray in a fixed and stable position.
