Capacitive Support Fabric for Clear Crowd Cheering Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In crowded events, it is often unclear which athlete or team audience support is directed to, leading to confusion and lack of clear recognition of support degrees.
Innovation Solution
An event system utilizing capacitive sensors sewn into fabrics to detect changes in capacitance, transmitting signals to control devices that adjust venue equipment states, such as displays, acoustic devices, and illumination, to reflect support degrees visually and audibly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If audiences provide support through vocal cheering in crowds, then support can be expressed, but it becomes unclear which athlete or team the support is directed to
Solution Approach 1:
The patent replaces the mechanical/acoustic system of vocal cheering with an electronic sensing system. Capacitive sensors detect changes in capacitance caused by audience members touching or approaching the fabric, converting physical contact into electrical signals that can be processed and displayed, thereby eliminating the ambiguity of vocal support direction.
Solution Approach 2:
The patent utilizes visual feedback through color changes in the fabric or associated displays to indicate support direction. When capacitance changes are detected, the system can change colors or light patterns to show which athlete or team is receiving support, making the support direction visually clear to all audience members.
2Loss of information
If venue equipment is used to display support information, then recognition of support degree is improved, but the system complexity increases
Solution Approach 1:
The patent makes the fabric serve multiple functions: it acts as both the structural material and the sensing element. The capacitive sensors are integrated directly into the fabric, allowing the same object to provide both mechanical support and electronic sensing capabilities, thereby reducing overall system complexity.
Solution Approach 2:
The fabric with integrated capacitive sensors is self-sufficient in detecting support actions. The sensors automatically detect capacitance changes when touched or approached, requiring no additional complex processing or external systems to initiate the detection process.

AI summary
To facilitate recognition of a degree of support for a support target. An event system includes: a control device configured to control venue equipment of an event venue; a capacitive sensor configured to detect a change in capacitance between conductive threads sewn into a fabric; and a terminal device configured to transmit, to the control device, an output signal outputted from the capacitive sensor or a control signal generated based on the output signal, the control device changing, based on the output signal or the control signal, a state of the venue equipment.
