Solution Overview

Problem

Electric guitars require extensive amplification and transportation equipment, making it inconvenient to carry and transport, and existing guitar cases often provide inadequate protection and consume excessive space.

Innovation Solution

A guitar case with a built-in amplifier and speaker system, featuring a split-body design with a hinge and retractable spine for protection, integrated carry straps, and wheels for mobility, allowing the case to function as both a protective enclosure and a portable amplifier system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If a separate amplifier and speaker system is used with an electric guitar, then amplification function is provided, but transportation convenience deteriorates due to increased equipment quantity and weight

Engineering Contradiction:
Improveamplification functionVSAvoidtransportation convenience
Core Design Contradiction:
PowerVSEase of operation

Solution Approach 1:

The patent combines the amplifier and speaker system directly into the guitar case structure. The amplifier is integrated into the case body with speakers positioned to provide acoustic output, eliminating the need for separate amplifier equipment and reducing the total number of components to transport.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The guitar case is designed to serve multiple functions: it provides instrument protection during transport, stores accessories and equipment, and functions as a portable amplifier system. This multi-functionality reduces the need for separate dedicated equipment for each purpose.

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

2Ease of operation

If traditional guitar cases are used, then transportation function is provided, but protection adequacy deteriorates due to insufficient structural reinforcement

Engineering Contradiction:
Improvetransportation functionVSAvoidprotection adequacy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The case is divided into an upper body and lower body connected by a hinge, with the spine providing structural segmentation and reinforcement. This segmented design allows for both protection and controlled opening mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The case incorporates a retractable spine that can be extended to provide additional structural support and protection for the guitar neck during transport. The spine acts as a pre-positioned protective element that can be deployed when needed.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Ease of operation

If traditional guitar cases are used, then transportation function is provided, but storage space efficiency deteriorates due to excessive space consumption

Engineering Contradiction:
Improvetransportation functionVSAvoidstorage space
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The case design allows the upper body to be folded down against the lower body, creating a compact nested configuration for storage. The hinge mechanism enables the upper body to be positioned within the footprint of the lower body, reducing overall storage volume when not in use.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Adaptability or versatility

If the case is designed with integrated amplifier components, then functionality is improved, but device complexity increases

Engineering Contradiction:
Improveintegrated amplificationVSAvoidcase structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The amplifier system is integrated into the case as a distinct module within the case structure, separating the electronic components from the structural elements. This modular integration maintains case functionality while adding amplification capabilities.

Inventive Principle:
Principle #1Segmentation

AI summary

A guitar case comprises an upper body, a lower body, pivotally connected to the upper body, so that the upper body and lower body have a first closed configuration, for housing a guitar, the stowed guitar extending between the upper body and the lower body, the upper body and lower body have a second open configuration where the upper body is pivoted adjacent to the lower body. An amplifier and speakers are situated in the upper body, the speakers being directed outwards from the guitar case. Alternatively, the guitar case comprises a body an amplifier and two speakers, situated in the body, the two speakers positioned in a spaced relationship, the space separating them forming part of a cavity for accommodating the neck of a guitar the two speakers are joined a reinforcing yoke extending across the part of a cavity formed between the two speakers.
