Stadium Stand Configurable Cross-Sectional Profile for Consistent C-Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern sports stadiums with straight seating layouts provide inconsistent spectator viewing quality due to varying C-values across seats, leading to reduced atmosphere and increased costs, while curved seating layouts attempt to mitigate this but result in larger structures and variable viewing experiences.
Innovation Solution
A stadium stand design with a configurable cross-sectional profile that allows for consistent C-values across seats by varying the rake and shape of the structure along its depth, enabling improved viewing quality and atmosphere by ensuring each seat has a substantially constant C-value, which can be adjusted based on the field of play and spectator requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If straight seating layout is used, then every seat is at constant distance from field edge, but viewing quality varies and atmosphere is reduced
Solution Approach 1:
The patent applies local quality by varying the cross-sectional profile of the stand structure along its width. Different sections of the stand have different rake angles and elevations tailored to their specific position, ensuring that each seat achieves optimal viewing geometry rather than applying a uniform profile throughout. This allows consistent viewing quality across all seats while maintaining the structural efficiency of straight seating.
2Ease of operation
If curved seating layout is used, then atmosphere is improved and peripheral view is enhanced, but structure size increases and viewing quality varies
Solution Approach 1:
The patent employs asymmetry by configuring the stand with straight sides in plan view but implementing asymmetric cross-sectional profiles at different locations. The profile varies along the width to compensate for position-dependent viewing angles, creating an asymmetric elevation pattern that maintains consistent C-values without requiring curved geometry. This achieves atmospheric enhancement through optimized viewing geometry while keeping the structural footprint compact.
3Manufacturing precision
If curved seating with varying profile is used, then C-value consistency is improved, but structure height and depth increase
Solution Approach 1:
The patent applies parameter changes by systematically varying the rake angle and elevation parameters of the stand structure along its width. Rather than using a uniform profile or overly conservative height increases, the invention optimizes these geometric parameters at each location to achieve the target C-value. This allows consistent viewing quality while minimizing the overall height and depth of the structure through precise parameter optimization.

AI summary
The present disclosure relates to a stand for a stadium. The stand comprises, a plurality or rows, each row containing a plurality of seats, and a structure having a width and a depth, wherein the plurality of rows of seats are mounted to the structure. The cross-sectional profile of the structure along the direction of the depth of the structure varies along the direction of the width of the structure such that a C-value for each of the plurality of seats is configurable. In a preferred embodiment, the C-value is configured to be substantially constant. A method of configuring the arrangement of such a stand is also disclosed.
