Magnetic Shield Assembly for Transducer Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for projecting music and vibrations into bath tubs and shower enclosures using electromagnetic transducers often generate magnetic fields that interfere with electronic devices, such as pacemakers, and complicate maintenance or vibration transmission.
Innovation Solution
A magnetic shield assembly is mounted on the exterior of the plumbing fixture, with a transducer positioned within a cavity, and a vibration-transmitting post extends through the shield to maintain effective vibration transmission while minimizing magnetic field exposure, allowing for easy transducer removal and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an electromagnetic transducer is placed outside the fixture against the exterior wall to project vibrations, then the vibrations can be transmitted to the fixture, but magnetic fields are generated that may interfere with electronic devices such as pacemakers
Solution Approach 1:
A magnetic shield is introduced as an intermediary component between the electromagnetic transducer and the fixture interior. The shield is positioned with its magnetically permeable surface facing the transducer, creating a magnetic flux path that contains the magnetic field within the shield structure while allowing vibration transmission through dedicated openings.
2Object-affected harmful factors
If a magnetic shield is placed between the transducer and the fixture interior to block magnetic fields, then magnetic field interference is reduced, but vibration transmission may be degraded
Solution Approach 1:
The magnetic shield is designed with non-uniform properties: the front surface facing the transducer is made of magnetically permeable material to contain magnetic fields, while specific localized openings are provided to allow vibration transmission. This local differentiation of properties enables simultaneous achievement of magnetic shielding and vibration transmission.
3Ease of operation
If the transducer is permanently mounted to the fixture to ensure stable vibration transmission, then vibration effectiveness is improved, but the ability to remove and replace transducers is interfered with
Solution Approach 1:
The mounting system is segmented into separate components: a mounting bracket attached to the fixture and a removable mounting mechanism that connects the transducer to the bracket. This segmentation allows the transducer to be easily removed and replaced while maintaining stable vibration transmission during operation through the structured mounting interface.
