Flexible Shape-Memory Advertising Device for Goal Area Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing advertisement devices for sports fields, particularly near goal nets, pose safety risks to players due to collisions and are affected by humidity, leading to reduced visual impact.
Innovation Solution
A flexible advertisement device with shape-memory material, designed to resemble the goal net without being physically attached, featuring a support with a longitudinal channel and transverse orifices for anchoring, and a camouflage exterior to blend with the terrain, ensuring safety and maintaining visibility in rainy conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional advertisement devices are placed in the goal area, then advertisement impact is improved, but safety risk to sportspeople increases
Solution Approach 1:
The patent introduces a flexible support structure as an intermediary element that allows the advertisement device to be positioned in the goal area without directly obstructing player movement. The flexible nature of this intermediary structure absorbs impact forces, preventing injury while maintaining advertisement visibility in the high-impact goal zone.
Solution Approach 2:
The advertisement device employs flexible materials for its support structure and mounting mechanisms. This flexibility allows the device to deform under impact rather than rigidly obstructing players, thereby reducing injury risk while maintaining structural integrity and advertisement display functionality in the goal area.
2Illumination intensity
If transparent laminar elements are used for advertisement display, then visual impact is improved, but visibility deteriorates in humid conditions
Solution Approach 1:
The patent addresses the humidity vulnerability of transparent laminar elements by changing the material parameters of the support structure and mounting components. By selecting materials with appropriate hydrophobic properties and structural characteristics, the device maintains its visual impact and advertisement clarity even in rainy or humid conditions, preventing misting and water accumulation.
3Illumination intensity
If advertisement devices are placed vertically on the ground, then advertisement visibility is improved, but stability decreases
Solution Approach 1:
The patent transitions from a purely vertical ground-mounted configuration to a multi-dimensional positioning system that incorporates angled supports and adjustable mounting mechanisms. This dimensional change allows the advertisement device to achieve both optimal vertical visibility for spectators and camera angles, while the distributed multi-point anchoring provides enhanced stability against toppling forces.
