Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Flute players face difficulties in controlling the airstream over the embouchure hole due to ambient air currents, especially in windy conditions, which affects their ability to produce notes effectively.

Innovation Solution

A detachable wind guard designed as an elongate, arcuate cover that wraps over the flute barrel with a center section providing clearance for the embouchure hole and vent holes positioned perpendicular to the airstream, combined with a clamshell mechanism for easy operation, effectively blocking unwanted air currents while allowing unobstructed airflow for the musician's lips.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a wind guard is added to block ambient air currents, then protection from harmful wind is improved, but device complexity increases

Engineering Contradiction:

Improveprotection from ambient air currentsVSAvoidstructure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The wind guard is divided into multiple segments: a cover portion that wraps over the flute barrel, a holder portion that wraps under the barrel, and a hinge connecting them. This segmentation allows each part to perform its specific function while maintaining overall simplicity and protect the flute from ambient air currents effectively.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The hinge mechanism allows the wind guard to be dynamically opened and closed, enabling the player to adjust protection levels as needed. The torsion springs provide automatic return to closed position, making the device adaptive to different playing conditions without increasing permanent complexity.

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If a cover is placed over the flute barrel to block wind, then protection from harmful factors is improved, but ease of operation deteriorates due to restricted access

Engineering Contradiction:

Improveshielding embouchure hole from windVSAvoidaccess to embouchure hole

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The cover is designed with an opening that exposes the embouchure hole while surrounding it with protective walls. This segmentation of coverage allows wind protection for the upper and side portions of the embouchure area while maintaining unobstructed access from the player's lips, resolving the contradiction between protection and accessibility.

Inventive Principle:

Principle #1Segmentation

3Productivity

If vent holes are added to the cover, then airflow control is improved, but device complexity increases

Engineering Contradiction:

Improveairflow control for sound productionVSAvoidnumber of components

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Vent holes are strategically positioned in specific locations on the cover to allow controlled airflow through the wind guard. This local modification of the cover structure enables proper airflow for sound production without requiring additional complex components, as the holes are simply features of the existing cover portion.

Inventive Principle:

Principle #3Local quality

4Ease of operation

If a hinged clamshell mechanism is used for the wind guard, then ease of operation is improved through one-hand operation, but device complexity increases

Engineering Contradiction:

Improveone-hand operation capabilityVSAvoidhinge and spring mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The hinge mechanism combines the cover portion and holder portion into a single integrated unit that operates together as one assembly. The torsion springs are integrated into the hinge mechanism itself, allowing one-hand operation to open and close the entire wind guard structure without requiring separate operations for different components, thus improving ease of operation while keeping the complexity manageable through functional integration.

AI summary

The invention provides a detachable wind guard for a flute-type instrument comprising an elongate, arcuate cover configured to wrap over a flute barrel. The cover has a center section with a radius larger than the radius of the flute barrel and includes a tapered, recessed facing edge configured to leave an embouchure hole uncovered when the wind guard is attached to the flute barrel. End sections taper to a radius sized to conform to the flute barrel. An elongate, arcuate holder positioned opposite the cover has a radius sized to conform to the flute barrel. A connector pin passes through knuckles on both the cover and holder to form a hinge that allows the wind guard to open in a clamshell manner. Torsion springs around the connector pin bias the holder in a closed position.
