Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional string instruments lack a unique design and sound resonance, as they typically rely on standard shapes and materials, failing to provide a distinct auditory experience.
Innovation Solution
A string instrument design featuring a body with a metal plate resembling a shovel head, which includes a convex and concave surface, coupled with pickups and capacitors, to resonate vibrations and produce a unique sound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional string instruments use standard shapes and materials, then manufacturing is easier and production is standardized, but the sound resonance and design uniqueness are compromised
Solution Approach 1:
The instrument body combines traditional wood with a metal plate (shovel head) to create a composite structure. The metal plate provides unique sound resonance and distinctive appearance, while the wooden body maintains traditional guitar construction methods. This composite approach achieves design uniqueness without completely abandoning conventional manufacturing techniques.
Solution Approach 2:
Instead of changing the entire instrument body shape, the patent applies a metal plate with specific convex and concave surfaces to a localized portion of the guitar body. This local modification provides unique sound characteristics and visual distinction while keeping the overall instrument structure and manufacturing process relatively conventional.
2Quantity of substance
If conventional instruments use standard materials, then production costs are lower and manufacturing is simpler, but sound resonance and auditory experience are not distinct
Solution Approach 1:
The patent introduces a metal plate (shovel head) as an additional material element within the instrument body. This metal component provides distinctive sound resonance and visual appearance while being integrated into the existing wooden guitar structure through standard joining techniques, thus adding material variety without excessive manufacturing complexity.
3Shape
If the metal plate has convex and concave surfaces, then sound resonance is improved and design is unique, but manufacturing precision requirements increase
Solution Approach 1:
The metal plate incorporates convex and concave curved surfaces that are consistent with the traditional shovel head shape. These curved surfaces are achieved through standard metal forming and shaping techniques, creating the necessary acoustic properties without requiring extremely high manufacturing precision. The curvature is functional rather than overly complex.
