Drum Coupler with Adjustable Distance Mechanism for Varying Shell Heights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drum and drum stand couplers are not adaptable to drums with greater size differences, limiting their ability to securely couple drums of varying heights and shell sizes with a drum stand.
Innovation Solution
The coupler design includes arched first and second couplers with elongate adjustment slots on the left and right sides for transverse fasteners to couple with longitudinal fasteners on the drum shell, along with a distance adjustment mechanism using guiding members and fastening elements to securely attach drums of different sizes to a drum stand, providing a firmer fastening effect and accommodating varying heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional coupler design is used, then the structure is simple, but it is not adaptable to drum shells of greater size differences
Solution Approach 1:
The coupler incorporates adjustable components including elongate adjustment slots that allow the position of fastening elements to be moved along the slots, enabling the coupler to adapt to different drum shell sizes. The distance adjustment means allows the vertical distance between first and second couplers to be modified, providing dynamic adaptability to various drum configurations.
Solution Approach 2:
The coupler is divided into separate functional components: first coupler, second coupler, distance adjustment means, and fastening elements. This segmentation allows each component to be independently adjusted and positioned to match the specific dimensions of different drum shells, enhancing overall adaptability.
2Adaptability or versatility
If the coupler is designed to accommodate greater size differences, then adaptability improves, but the fastening strength may be compromised
Solution Approach 1:
The fastening system allows for dynamic adjustment of fastener positions along the elongate adjustment slots, enabling the coupler to maintain secure fastening across drums of varying heights while preserving fastening strength through optimal positioning of fastening elements.
Solution Approach 2:
The position parameters of fastening elements can be changed along the adjustment slots, and the distance between couplers can be modified via the distance adjustment means, allowing the system to maintain appropriate fastening strength across different drum sizes by optimizing these parameters.
3Adaptability or versatility
If adjustment slots are added to the coupler, then adaptability to size differences improves, but the device complexity increases
Solution Approach 1:
The elongate adjustment slots provide a simple yet effective mechanism for adaptability, allowing fastening elements to be repositioned along the slots without requiring complex adjustment mechanisms. This maintains relatively simple device structure while achieving good adaptability to different drum shell sizes.

AI summary
A drum and drum stand coupler comprises a first coupler and a second coupler that respectively surround the circumference of a drum shell at an upper side and a lower side. The first and second couplers have respectively an adjustment slot on the left and right sides run through by a transverse fastener to couple to a longitudinal fastener of a drum. The coupler also includes a distance adjustment means to couple longitudinally the first and second couplers. The distance adjustment means includes a first guiding member and a second guiding member that are coupled in an up and down manner and staggered on the outer side and inner side, and run through by at least one fastening element to be fastened together. Thus multiple drums with varying heights can mate drum shells with different specifications. The distance adjustment means also has a fixture to couple with a drum stand.
