Solution Overview

Problem

Existing sound deflectors for wind instruments often face challenges in securely attaching to instruments with varying shapes and sizes, requiring excessive force that can damage the instrument and are not easily adjustable for optimal sound reflection.

Innovation Solution

A sound deflector with a hinge-connected upper and lower part, featuring laterally offset nubs with rounded edges, allowing for adjustable and secure attachment to different funnel curvatures and thicknesses, minimizing force required for fixation and preventing pressure point damage, with optional rubber nubs for enhanced adaptation and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing sound deflectors are attached to instruments with varying shapes and sizes, then attachment versatility is reduced, but securing the deflector requires excessive force that can damage the instrument

Engineering Contradiction:
Improveattachment versatilityVSAvoidfixation force
Core Design Contradiction:
Adaptability or versatilityVSForce

Solution Approach 1:

The mounting device is divided into an upper part and a lower part that can be attached separately to the inner and outer surfaces of the bell rim, with multiple knobs on each part that can be independently positioned to adapt to different instrument geometries

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hinge connection between the upper and lower parts allows the mounting device to dynamically adjust its configuration to match different bell shapes and sizes, enabling secure attachment without excessive force

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If existing sound deflectors are attached securely to the instrument, then attachment stability is improved, but adjustment for optimal sound reflection becomes difficult

Engineering Contradiction:
Improveattachment stabilityVSAvoidadjustment ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The hinge connection enables easy angular adjustment of the deflector surface relative to the mounting device, allowing optimal sound reflection positioning while maintaining stable attachment through the knob clamping mechanism

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The deflector surface is differentially positioned relative to the mounting device through the hinge, allowing independent optimization of the sound reflection angle while maintaining the stability of the attachment mechanism

Inventive Principle:
Principle #3Local quality

3Device complexity

If existing sound deflectors use simple mounting mechanisms, then device complexity is reduced, but adaptability to different instrument shapes is limited

Engineering Contradiction:
Improvemounting mechanism complexityVSAvoidinstrument shape adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The mounting device is segmented into upper and lower parts with multiple knobs each, allowing adaptation to different instrument geometries while maintaining a relatively simple overall structure that attaches to the bell rim

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting device with its hinge connection and multiple positionable knobs serves multiple functions: adapting to different bell shapes, enabling angular adjustment of the deflector, and providing stable attachment, all within a single integrated mechanism

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a sound deflector (1) for a wind instrument (S), having a sound deflector plate (2) and a device (3) for holding the deflector plate on the edge of a bell (S') of the wind instrument (S). The device (3) for holding the deflector plate (2) has a lower part and an upper part, each of which can be fastened to the outer surface or the inside of the bell edge (S'), and the upper and lower part are connected together by means of a hinge (4). According to the invention, the lower part and the upper part each has at least two knobs with rounded edges. When the upper and lower part are brought together, each of the knobs of the upper part and lower part are offset relative to each other. The sound deflector (1) allows a fastening on instruments with bell edges of different shapes and curvatures or on music stands. The offset arrangement of the knobs on the holding device allows a clamp-type fastening on a bell edge (S'). The sound deflector (1) according to the invention is thus universally applicable.
