Magnetic Snare Strainer Holding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snare strainers require cumbersome bolt operations for attaching and detaching snappy members and backside heads, leading to lengthy replacement times and handling difficulties.
Innovation Solution
The snare strainer design incorporates permanent magnets or elastically deformable engagement elements to securely attach and detach holding members without the need for bolts, allowing for easy exchange of snappy members and backside heads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If holding members are attached to support member using bolts, then the attachment is secure and reliable, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces the mechanical bolt-based fastening system with a magnetic field-based holding system. Permanent magnets embedded in the support member attract and hold the holding members without requiring bolts, thereby eliminating cumbersome bolt operations while maintaining secure attachment. This substitution resolves the contradiction by improving ease of operation without sacrificing attachment reliability.
2Strength
If bolts are used to attach holding members to support member, then the connection is strong and stable, but the replacement process becomes lengthy and complex
Solution Approach 1:
The patent substitutes the time-consuming mechanical bolt tightening process with an instantaneous magnetic attraction mechanism. The permanent magnets provide strong holding force immediately upon contact, eliminating the time required for bolt insertion and tightening. This resolves the contradiction by maintaining strong connection strength while dramatically reducing replacement time.
3Reliability
If multiple bolts are used to secure holding members, then the attachment is firm and prevents accidental detachment, but the device complexity increases
Solution Approach 1:
The patent replaces multiple mechanical bolts with a single permanent magnet or a small number of magnets embedded in the support member. The magnetic field provides uniform holding force across the holding member, securing it firmly without requiring multiple discrete fastening points. This simplifies the device structure while maintaining attachment security, resolving the contradiction between reliability and device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies the replacement process and improves handling by eliminating the need for tools, reducing the time required for replacing snappy members and backside heads, and preventing accidental detachment or breakage.
Implementation Method 1
At least one of the first strainer and the second strainer includes at least one permanent magnet so that the holding members are fixed to the support member due to a magnetic attraction exerted by the permanent magnet

AI summary
A snare strainer adapted to a snare drum is equipped with two strainers, which are attached to the opposite positions on the circumferential exterior of a cylinder of the snare drum and which control a snappy member to be selectively brought into contact with or separated from the backside head opposite to the drumhead. Herein, a moving base vertically moves along a fixed base attached to the circumferential exterior of the cylinder; holding members, which are tightly joined together so as to hold the terminal of the snappy member, are supported by a support member fixed to the moving base. The holding members are engaged with the support member due to a magnetic attraction exerted by permanent magnets. This makes it possible for the person to detachably attach the holding members to the support member without using tools; hence, it is possible to improve the handling of the snare strainer.
