Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen sounding systems face difficulties in removing and replacing the exciter and adjusting its position due to fixed connections, which can cause positional deviations and damage to the screen from magnetic fields.
Innovation Solution
A screen sounding system utilizing a magnetic element fixedly connected to the screen, where the exciter is coupled via magnetic attraction, allowing for easy removal, installation, and adjustment of the exciter's position without direct bonding, using a housing with a magnet and a magnetic-conducting steel sheet or soft magnet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the exciter is fixedly connected to the screen using double-sided adhesive tape or solvent adhesive, then the connection between exciter and screen is strong and stable, but the exciter becomes difficult to remove and replace and positional deviation cannot be easily corrected
Solution Approach 1:
The connection system is segmented into three independent components: the screen, the magnetic element, and the exciter. This allows the exciter to be separately positioned and connected through magnetic attraction rather than permanent bonding, enabling easy removal and repositioning while maintaining stable operation during use.
Solution Approach 2:
A magnetic element is introduced as an intermediary component between the screen and the exciter. This magnetic mediator enables the exciter to be held stably during operation while allowing for easy removal and repositioning by simply overcoming the magnetic attraction, eliminating the need for permanent adhesive bonding.
2Stability of the object's composition
If the exciter is fixedly connected to the screen, then the position is stable during operation, but the screen is easily damaged by magnetic field influence from the exciter
Solution Approach 1:
The magnetic element serves as a mediator that physically separates the exciter from the screen while maintaining positional stability through magnetic attraction. This intermediary structure prevents direct contact between the exciter's magnetic field and the screen, reducing magnetic field influence and potential damage to the screen.
Solution Approach 2:
The magnetic element is extracted as a separate component from both the screen and the exciter. By placing the magnetic element on the screen and attracting the exciter from a distance, the harmful magnetic field direct contact with the screen is eliminated while maintaining the necessary positional stability during operation.
3Reliability
If traditional adhesive bonding is used to connect exciter and screen, then the connection is permanent and stable, but component replacement and position adjustment become difficult
Solution Approach 1:
The magnetic element acts as an intermediary that provides reliable magnetic attraction for stable operation while allowing easy separation for maintenance and replacement. This magnetic connection mechanism enables the exciter to be reliably held during use but easily removed when maintenance or replacement is needed, without requiring adhesive removal processes.
