Transducer Mounting Component for Vacuum-Safe Membrane Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transducers are prone to shape deformation or breakage during transportation and attachment/detachment due to stress generated by vacuum suction on the minute vibrating membrane, affecting the accuracy of displacement.
Innovation Solution
A mounting component with a membrane support and a contact member that applies an upward attractive force without generating stress on the vibrating membrane, using either a cover or magnetic bodies to prevent deformation or breakage during attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vacuum suction is applied to hold the mounting component, then the component can be picked up and positioned, but stress is generated on the vibrating membrane causing shape deformation or breakage
Solution Approach 1:
A cover is introduced as an intermediary component between the suction holder and the vibrating membrane. The cover is suctioned by the mounting machine while the vibrating membrane remains protected from direct suction stress, eliminating the harmful effect while maintaining the attachment function
Solution Approach 2:
The mounting component is divided into separate functional zones: a suction reception area (cover or contact member) that interfaces with the mounting machine, and a protected vibrating membrane area that performs its function without exposure to suction stress. This spatial segmentation allows differential treatment of different components
2Productivity
If the air in the space around the vibrating membrane is sucked by vacuum pressure, then the mounting component can be held, but stress is generated on the membrane affecting displacement accuracy
Solution Approach 1:
The cover acts as a mediator that receives the suction force while preventing the transmission of this force to the vibrating membrane. This allows the mounting operation to proceed efficiently while the membrane maintains its precise displacement characteristics unaffected by suction stress

AI summary
Provided is a mounting component held so as to be capable of attachment and detachment by a mounting machine. The mounting component includes a membrane support, a vibrating membrane connected to the membrane support and displaceable in a membrane thickness direction, and a contact member that is located on the membrane support and is subjected to an upward attractive force by the mounting machine without generating stress leading to shape deformation or breakage of the vibrating membrane during the attachment and detachment.
