Musical Instrument Carrier with Overlapping Plate Coupling

Solution Overview

Problem

Conventional musical instrument carriers for performers, such as marching drum carriers, often cause costume damage and shifting issues due to a bulge formed by the fastening mechanism and inadequate holding force, especially when worn under costumes or with heavy instruments.

Innovation Solution

A musical instrument carrier design featuring a shoulder rest member and an abdomen rest member with curved or bent plate-like members that can be adjusted to increase surface contact area, using a coupling structure with overlapping plate-like members to minimize bulge and enhance holding force, allowing for better distribution of the instrument's weight and reduced shifting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a fastening rod holder with screw is used to clamp the support rod, then the structure can be assembled, but a bulge is formed that causes costume damage and poor appearance

Engineering Contradiction:

Improveassembly capabilityVSAvoidcostume damage

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent removes the fastening rod holder and screw from the structure, extracting the harmful clamping mechanism that creates the bulge. Instead, the support rod is directly integrated with the shoulder rest member and abdomen rest member through curved portions, eliminating the need for separate fastening components and preventing costume damage.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the support rod, shoulder rest member, and abdomen rest member into an integrated structure. The curved portions of these members directly connect to form a unified load-bearing structure, eliminating the need for separate fastening components and preventing costume damage.

Inventive Principle:

Principle #5Merging (Combining)

2Ease of manufacture

If a fastening rod holder with screw is used to clamp the support rod, then the structure can be assembled, but the appearance is degraded

Engineering Contradiction:

Improveassembly capabilityVSAvoidappearance

Core Design Contradiction:

Ease of manufactureVSShape

Solution Approach 1:

The patent removes the fastening rod holder and screw from the structure, extracting the harmful clamping mechanism that creates the bulge. Instead, the support rod is directly integrated with the shoulder rest member and abdomen rest member through curved portions, eliminating the need for separate fastening components and preventing costume damage.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of manufacture

If the fastening rod holder clamps the support rod, then the components can be connected, but the holding force is weak causing shifting

Engineering Contradiction:

Improvecomponent connectionVSAvoidholding force

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent merges the support rod, shoulder rest member, and abdomen rest member into an integrated structure. The curved portions of these members directly connect to form a unified load-bearing structure, eliminating the need for separate fastening components and preventing costume damage.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent employs curved portions in the shoulder rest member and abdomen rest member that wrap around the support rod. This curvature increases the contact area between the components, distributing the load more effectively and providing stronger holding force to prevent shifting during performance.

Inventive Principle:

Principle #14Spheroidality (Curvature)

AI summary

A musical instrument carrier includes a shoulder rest member that is abutted on the shoulders of a performer and an abdomen rest member that is provided separately from the shoulder rest member, that includes a portion coupled to the shoulder rest member, and that is abutted on the abdomen of the performer, in which coupling between the shoulder rest member and the abdomen rest member is achieved by plate-like members having a curved portion or a bent portion being overlapped and affixed in a state of making surface contact, and by changing the position at which the curved portions or bent portions overlap, it is possible to change the angle of the abdomen rest member with respect to the shoulder rest member.
