Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stage control devices require manual adjustment by technicians to achieve balanced sound and lighting effects, which is challenging for non-professionals and not adaptable to small settings, and they fail to consider device characteristics for optimal output.
Innovation Solution
A method where a control terminal automatically adjusts sound and illumination balance by comparing output data from devices with sample data, using sensors and position information to optimize output levels and directions, reducing the need for manual intervention and specialized equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual balance adjustment by technicians is used, then sound and lighting balance can be adjusted, but it requires professional skills and is difficult for non-professionals
Solution Approach 1:
The system automatically performs balance adjustment by itself without requiring technician intervention. The control module collects output data from multiple devices, compares it with sample data, and automatically generates adjustment signals to achieve balanced sound and lighting effects, making the system self-sufficient in balance adjustment tasks
Solution Approach 2:
The system implements a feedback mechanism where the control module continuously monitors output data from sound and lighting devices, compares it with pre-stored sample data representing ideal balance, and automatically adjusts device outputs based on the comparison results to achieve and maintain optimal balance
2Reliability
If high-priced stage control devices and programs are used, then three-dimensional sound and lighting effects can be achieved, but it is not economical for small directing areas
Solution Approach 1:
The control module is designed to perform multiple functions: it controls various sound and lighting devices, automatically adjusts their balance, stores sample data for different scenarios, and adapts to different directing area sizes. This multi-functionality eliminates the need for separate expensive specialized equipment for each function
Solution Approach 2:
The system uses pre-stored sample data that represents ideal three-dimensional sound and lighting effects. By copying and comparing against these sample patterns, the system can reproduce high-quality effects without requiring expensive real-time professional adjustment or specialized hardware for each effect type
3Adaptability or versatility
If conventional stage control devices are used, then balance adjustment is possible, but it cannot consider device characteristics and output result characteristics
Solution Approach 1:
The system individually characterizes each connected device by having them output test signals and measuring their specific output characteristics. Each device's unique properties (such as speaker sensitivity, lighting intensity, directional patterns) are recorded and stored. During operation, the control module uses this device-specific information to make tailored adjustments, ensuring each device operates at its optimal characteristics rather than applying uniform adjustments
4Productivity
If manual balance adjustment is used, then technicians can adjust sound and lighting, but it requires time-consuming manual intervention
Solution Approach 1:
The system performs preliminary actions by pre-storing sample data representing ideal three-dimensional sound and lighting effects for various scenarios. When adjustment is needed, the control module simply compares current output against these pre-prepared samples and automatically executes corrections, eliminating the need for time-consuming manual trial-and-adjustment processes

AI summary
The present invention relates to a balance adjustment control method for sound/illumination devices and, more particularly, to a method for controlling balance adjustment of sound/illumination devices, which is performed by a control terminal performing a sound or illumination adjustment function for a performance area in which sound/illumination devices including at least one device among a plurality of sound devices, a plurality of sound output devices, a plurality of sound input devices, and a plurality of illumination devices are installed, the method comprising the steps of: allowing, by the control terminal, basic data, in which multiple pieces of sample sound data for the sound devices or human voices or sample illumination data for each illumination device are stored, to be input, the basic data including at least one piece of information among size information, open information, device information, and audience information of the performance area; extracting at least one piece of sample sound data or sample illumination data corresponding to the performance area on the basis of the basic data and transmitting the extracted sample sound data or sample illumination data to a control device for controlling the operation of the sound illumination device; performing at least one scheme by the control terminal, among a scheme allowing an output sound output from the plurality of sound output devices to be input when the sample sound data is output through the plurality of sound output devices by the control device and a scheme allowing input illumination data obtained by measuring an illumination output state of the illumination devices to be input when the sample illumination data is output through the plurality of illumination devices by the control device, so that input sound data for the output sound or the input illumination data for the illumination output state is input; and performing at least one scheme by the control terminal, among a scheme of generating a sound balance adjustment signal for each of the sound output devices by comparing the input sound data and the sample sound data, and then transmitting the generated signal to the control device and a scheme of generating an illumination balance adjustment signal for each of the illumination devices by comparing the input illumination data and the sample illumination data, and then transmitting the generated signal to the control device. Therefore, the present invention enables automatic execution of balance adjustment of each sound output device or each illumination device within a performance area, thereby making it unnecessary for a sound or illumination-related engineer to manually adjust the balance and enabling anyone to easily adjust the balance of sound or illumination using the control terminal. Moreover, in the present invention, a plurality of control devices for controlling devices in a performance area is unnecessary and only one control device capable of communicating with the control terminal is used. Therefore, the present invention can lower the device failure rate and prevent overload.
