Innovation Solution
A mute equipment with a hole to release breath and a section to restrict wind way width, adjustable by a ring, allowing flexible control of breath volume and compatible with various wind instrument shapes, including an adapter for easy attachment and detachment, made from materials like silicon rubber to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If conventional mute equipment is attached to wind instruments with air reed, then sound volume is reduced, but breath pressure control is lost and pitch accuracy deteriorates
Solution Approach 1:
The patent introduces a mute equipment with a breath pressure control mechanism as an intermediary device between the player and the wind instrument. This mediator not only reduces sound volume through the mute function but also actively controls breath pressure to maintain pitch accuracy, resolving the contradiction between sound reduction and pitch preservation
Solution Approach 2:
The patent changes the physical parameters of the breath flow by introducing adjustable restrictions in the breath path. By modifying breath pressure and flow rate parameters through the control mechanism, the system achieves both sound volume reduction and pitch accuracy maintenance simultaneously
2Object-generated harmful factors
If mute equipment is attached to ocarinas with urceolate shape, then sound is muted, but the equipment may damage the instrument due to improper fit
Solution Approach 1:
The patent employs flexible materials for the mute equipment structure that can adapt to the urceolate shape of ocarinas. This flexibility allows the equipment to conform to various instrument shapes without causing damage, while still achieving effective sound muting
Solution Approach 2:
The mute equipment incorporates adjustable and adaptable components that can dynamically adjust to different instrument geometries. This dynamic adaptability ensures proper fit across various ocarina designs without risking instrument damage
3Object-generated harmful factors
If breath volume is reduced to mute sound, then sound pressure is lowered, but tone quality and pitch are affected
Solution Approach 1:
The patent independently controls breath pressure parameters separate from breath volume reduction. By maintaining optimal breath pressure through the control mechanism while reducing overall breath volume, the system achieves sound pressure reduction without compromising tone quality or pitch stability
4Object-generated harmful factors
If conventional mute equipment is used for different wind instrument shapes, then sound muting is achieved, but adaptability to various instrument designs is poor
Solution Approach 1:
The patent designs the mute equipment with universal adaptability features that allow it to function effectively across different wind instrument types and shapes. The equipment incorporates adjustable components and flexible materials that enable it to adapt to various instrument geometries while maintaining sound muting effectiveness
Solution Approach 2:
The mute equipment features dynamic adjustability that allows it to conform to different instrument shapes and sizes. This dynamic adaptation capability enables the same equipment design to work effectively across multiple wind instrument types without sacrificing muting performance
