Transducer Spring Attachment via Radial Interference Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical devices, particularly those involving electromagnetic transducers, face challenges in efficiently attaching counterweight apparatuses to springs without using retention components like adhesives or piercing mechanisms, which can compromise reliability and durability.
Innovation Solution
The development of an electromagnetic transducer design that utilizes a spring connected to a counterweight apparatus, where the spring positively interferes with the counterweight to attach it, enabling relative movement and attachment without the need for retention components like adhesives or piercing, using a radial connection and elastic deformation for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If retention components like adhesives or piercing mechanisms are used to attach the counterweight apparatus to the spring, then the attachment can be achieved, but the reliability and durability are compromised
Solution Approach 1:
The patent removes retention components (adhesives, piercing mechanisms) from the attachment system, extracting the problematic elements that compromise reliability while maintaining the essential attachment function through a simplified interference fit mechanism
Solution Approach 2:
The spring and counterweight apparatus are designed to self-attach through their geometric interference fit, eliminating the need for external retention components. The system serves itself by using the inherent shapes and dimensions of the parts to create a secure, reliable attachment without additional fastening elements
2Reliability
If a secure attachment mechanism is implemented, then the counterweight apparatus can be reliably attached to the spring, but the transduction functionality may be compromised
Solution Approach 1:
The attachment function and transduction function are segmented into separate design considerations: the interference fit provides secure attachment while the radial connection geometry and elastic deformation properties are optimized independently to maintain transduction efficiency
Solution Approach 2:
The spring component serves multiple functions simultaneously: it provides mechanical support, enables relative movement, creates secure attachment through interference fit, and facilitates energy transfer. The radial connection design allows the same structure to fulfill both attachment and transduction requirements without compromise
3Ease of operation
If relative movement is enabled between the counterweight apparatus and yoke, then the transducer can function properly, but the attachment security may be reduced
Solution Approach 1:
The attachment mechanism transitions from a static rigid connection to a dynamic elastic connection. The spring provides a flexible attachment that allows controlled relative movement while maintaining security through elastic deformation and interference fit, adapting to operational requirements
