Drum Holder System with Adjustable Opening and Split Ring Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tom-tom drum holders are limited by fixed rod diameters and ball-and-socket joints that cannot accommodate rods of different diameters and do not allow for linear adjustment, leading to potential deformation upon clamping.
Innovation Solution
A holder system with an adjustable opening and clamping structure that allows holding rods of various diameters to move linearly and rotate, using a fastener to secure the rod and a resilient split ring to prevent deformation, enabling simultaneous locking of the rod and shaft with a single movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a ball and socket joint is used to connect the shaft and rod, then the angular relationship can be adjusted, but the rod cannot be moved linearly and the ball may become deformed over time
Solution Approach 1:
The holder system is divided into separate functional components: a holder body with a first opening for the shaft, a holding structure with a second opening for the rod, and a fastener to connect them. This segmentation allows each component to perform its specific function independently - the holder body provides angular adjustment via the shaft, while the holding structure provides linear adjustment via the rod, eliminating the deformation problem of the ball and socket joint.
Solution Approach 2:
The fastener acts as an intermediary element between the holder body and the holding structure. It threadedly connects the two separate structures, allowing them to move independently in their respective directions while maintaining a secure connection. This intermediary mechanism enables both angular adjustment of the shaft and linear adjustment of the rod without the deformation issues of direct ball and socket connection.
2Reliability
If the rod is fixed to the ball with a specified rod diameter, then the connection is secure, but the rod cannot work with various brackets on a tom-tom drum
Solution Approach 1:
The holding structure is designed with a second opening that can accommodate rods of different diameters. The holding members are positioned to define this adjustable opening, allowing the system to adapt to various rod sizes. This dynamic design enables the same holder body to work with different brackets and rod configurations, maintaining secure connection while improving versatility.
Solution Approach 2:
The holder system is designed to be universal by accommodating multiple rod diameters through the adjustable second opening in the holding structure. The fastener and holding members are configured to securely hold rods of varying sizes, allowing a single holder body to interface with different brackets and drum configurations, thereby achieving multi-functionality and broad compatibility.
3Device complexity
If a conventional holder system is used, then the structure is simple, but it cannot accommodate rods of different diameters and causes deformation upon clamping
Solution Approach 1:
The holder system is divided into separate functional components: a holder body with a first opening for the shaft, a holding structure with a second opening for the rod, and a fastener to connect them. This segmentation allows each component to perform its specific function independently - the holder body provides angular adjustment via the shaft, while the holding structure provides linear adjustment via the rod, eliminating the deformation problem of the ball and socket joint.
4Reliability
If the holding rod is secured with a fastener, then the rod is locked in position, but the rod cannot be adjusted linearly during operation
Solution Approach 1:
The holding structure is designed with a second opening that can accommodate rods of different diameters. The holding members are positioned to define this adjustable opening, allowing the system to adapt to various rod sizes. This dynamic design enables the same holder body to work with different brackets and rod configurations, maintaining secure connection while improving versatility.
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
The system allows for secure adjustment and use of rods of different diameters without deformation, providing flexible mounting options for tom-tom drums and preventing movement of the holding rod and shaft during clamping.
Implementation Method 1
A resilient, generally cylindrical split ring is fixed to the body. The split ring has an adjustable bore there-through, with the pin being engaged with the split ring. The lower holding member pushes on the pin which causes the bore of the split ring to reduce in size causing the split ring to clamp on the clamping members

AI summary
A holder system for a drum includes a body, holding structure within the body defining an adjustable opening, a fastener threadedly received in the body and engageable with the holding structure, a holding rod received in the opening such as to be able to be moved linearly and to rotate with respect to the body. Clamping structure has a portion disposed within the body and is associated with the holding structure. A shaft is received by the clamping structure such that the shaft can rotate about an axis thereof and rotate with respect to the body. When the fastener moved to engage the holding structure, the opening reduces in size and thus causes the holding structure to prevent any movement of the holding rod and, substantially simultaneously, a portion of the holding structure engages a part of the clamping structure causing the clamping structure to prevent any movement of the shaft.
