Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional snare wire attachment structures using snare frames often hamper the resonance of the snare drum by causing the end plates of the snare wire to bite into the back-surface head, obstructing the vibration sound, and using link components further reduces resonance by fixing the snare frame rigidly with the drum.

Innovation Solution

A snare wire attachment structure utilizing a snare frame with flexible coupling members, such as strings made of materials like polyethylene or nylon, which allows the frame end sections to be arranged outwardly, preventing the end plates from biting into the back-surface head and maintaining the snare wire's vibration, thus enhancing resonance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the string is pulled intensely to increase the amount by which the snare portion contacts the back-surface head, then the contact amount increases, but the end plates bite into the surface of the back-surface head and hamper vibration

Engineering Contradiction:

Improvecontact amount of snare portionVSAvoidend plates biting into back-surface head

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent divides the frame into a body portion and separate end sections that are positioned outward relative to the drum head. This segmentation allows the snare wire contact function to be separated from the structural support function, enabling the end sections to be positioned away from the drum head surface to prevent biting while maintaining proper snare portion contact.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent positions the frame end sections in a different spatial dimension - outward relative to the outer peripheral edge of the drum head - rather than allowing them to extend over the head surface. This dimensional repositioning prevents the end plates from contacting and damaging the drum head while maintaining the functional integrity of the snare wire attachment.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If link members made of rigid material are used to hold the snare frame, then the frame is fixed firmly, but the vibration of the snare frame and snare wire is hampered and resonance decreases

Engineering Contradiction:

Improveframe fixation stabilityVSAvoidresonance of vibration sound

Core Design Contradiction:

Stability of the object's compositionVSLoss of energy

Solution Approach 1:

The patent replaces rigid link members with flexible strings made of materials such as polyester, nylon, or polyethylene. These flexible coupling members can transmit the necessary holding force while allowing the snare frame and wires to vibrate freely, thereby maintaining resonance and preventing energy loss that would occur with rigid fixation.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent changes the physical parameters of the coupling members from rigid to flexible by selecting materials with appropriate elastic properties. This parameter change allows the coupling members to provide stable fixation while simultaneously permitting the vibration and resonance necessary for proper snare drum function.

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If the frame end sections are positioned over the drum head to secure the snare wire, then attachment is simplified, but the end plates interfere with drum head vibration and obstruct resonance

Engineering Contradiction:

Improvesnare wire attachment simplicityVSAvoidend plate interference with vibration

Core Design Contradiction:

Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent segments the frame structure into a body portion that provides attachment functionality and separate end sections that are positioned outward away from the drum head. This segmentation allows the attachment function to be maintained while eliminating the harmful interference of end plates with drum head vibration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts the potentially harmful end plate elements from the drum head area by positioning the frame end sections outward relative to the outer peripheral edge of the drum head. This extraction removes the source of vibration interference while preserving the necessary snare wire attachment and tensioning functions.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A snare wire is attached to a snare drum using a snare frame. A string made of flexible material is employed as a coupling member for coupling the snare frame to the snare drum. In the state in which the snare wire is attached to the snare drum by means of the snare frame, frame end sections of the snare wire are each arranged outward with respect to the outer peripheral edge of the back-surface head.
