Wind Instrument Bell Ring Attachment via Elastic Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wind instrument bells face difficulties in removing the metal ring from the bell body, and when the bell body is made of wood, it can become loose due to contraction from drying.
Innovation Solution
A wind instrument bell with a cylindrical bell body featuring a recessed groove on its outer surface and a C-shaped ring that can be easily attached and detached by deforming its ends to fit within the groove, allowing for resilient fastening and easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a projection is formed on the inner circumferential surface of the ring to fit and fasten to the bell body, then the ring is securely fixed to the bell body, but it becomes difficult to remove the ring from the bell body
Solution Approach 1:
The ring is segmented into a C-shaped configuration with a gap between its ends, allowing it to be inserted into the recessed groove and deformed to fit securely, while also enabling easy removal by reversing the deformation process
Solution Approach 2:
The ring is designed to be elastically deformable, allowing it to dynamically change shape during attachment and detachment operations, transitioning from a relaxed C-shape to a compressed state when fitted into the recessed groove
2Reliability
If the bell body is made of wood, then it has desirable acoustic properties, but when the bell body contracts due to drying, the mounting state of the ring becomes loose
Solution Approach 1:
The ring's elastic properties are optimized to accommodate dimensional changes in the wooden bell body, allowing the ring to maintain secure mounting despite contraction or expansion of the wood due to humidity and temperature variations
Solution Approach 2:
The ring is designed as a flexible elastic component that can deform to accommodate changes in the bell body's dimensions, maintaining secure fastening even when the wooden bell body contracts or expands
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy attachment and detachment of the ring to the bell body, maintaining a secure fit even when the bell body contracts, and allows for varying tone colors by altering the ring's presence, enhancing sound quality and usability.
Implementation Method 1
by causing the ring to undergo deformation (plastic deformation or resilient deformation) so that the first end and the second end separate from each other
Implementation Method 2
by causing the ring to undergo deformation (plastic deformation or resilient deformation) so that the first end and the second end separate from each other

AI summary
A wind instrument bell includes a bell body and a ring. The bell body has a cylindrical shape, is configured to be connected to a wind instrument body, and has an outer circumferential surface having a recessed groove extending in a circumferential direction of the outer circumferential surface. The ring has a C shape, has a first end and a second end being separated from each other, and is accommodated in the recessed groove in a state of being deformed so that the first and second ends separate from each other.
