Solution Overview

Problem

Existing electronic wind instruments face challenges in fixing a casing and a bell formed from different materials, making the process difficult and requiring innovative solutions for secure attachment.

Innovation Solution

An electronic wind instrument design that includes a breath sensor, operating elements, a casing, a tubular bell, and a first separate material body forming a fixing member, which is attached to the casing and bell using bolts and nuts or adhesive, allowing for stable fixation even when materials differ.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the casing and bell are formed from different materials, then design flexibility and material properties can be optimized, but the difficulty of fixing them together increases

Engineering Contradiction:

Improvematerial selection flexibilityVSAvoiddifficulty of fixing casing and bell

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

A separate material body acts as an intermediary component between the casing and bell. This intermediate fixing member provides a standardized interface that can accommodate different materials, enabling the casing and bell to be securely fixed together despite material differences through standardized attachment mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If the casing and bell are formed separately, then manufacturing flexibility and material selection are improved, but the complexity of assembly increases

Engineering Contradiction:

Improvemanufacturing flexibilityVSAvoidassembly complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The instrument is divided into separate components (casing, bell, and fixing member) that can be manufactured independently using different materials and processes. The standardized fixing member provides a simple assembly interface that reduces overall assembly complexity despite the segmented structure.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If the casing and bell are directly fixed together, then assembly is simple, but it is difficult to achieve secure fixation when materials differ

Engineering Contradiction:

Improveassembly simplicityVSAvoidfixation security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The separate material body serves as a mediator that enables secure fixation between the casing and bell. It provides a standardized interface with appropriate mechanical properties that ensure reliable connection while maintaining assembly simplicity through standardized attachment mechanisms like threads or attachment protrusions.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An electronic wind instrument includes: a breath sensor; an operating element that receives an instruct related to a pitch; a casing to which the breath sensor and the operating element are provided; a bell having a tubular shape and facing the casing; and a first separate material body that forms a fixing member fixed to the casing and attached to an outer peripheral surface of the bell.
