Drum Frame Clamping Structure for Smooth, Low-Noise Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drum frame clamping structures experience smoothness issues and noise interference due to the direct application of weights from musical instruments or auxiliary devices on the adjusting stud, making rapid assembly and disassembly difficult.
Innovation Solution
A drum frame clamping stand with an upper and lower clamping piece pivotally connected via a rotary shaft, featuring a screw locking piece that rotates smoothly without direct force application, using a driving part with a non-rotating nut for shock absorption and a return spring for easy operation, allowing the upper clamping end to close and clamp the drum frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adjusting stud is used to clamp the drum frame with the L-shaped fixed clamping block, then the clamping function is achieved, but the weights of musical instruments or auxiliary devices directly act on the adjusting stud, resulting in unsmooth rotation and easy loosening
Solution Approach 1:
The clamping structure is segmented into an L-shaped fixed clamping block for lower edge clamping and a movable clamping block for upper edge clamping, with the locking and connecting structure separately supporting musical instruments or auxiliary devices. This segmentation prevents the weights from directly acting on the adjusting stud, ensuring smooth rotation while maintaining reliable clamping.
Solution Approach 2:
The locking and connecting structure serves as an intermediary element that supports musical instruments or auxiliary devices, transferring their weights to the clamping blocks rather than directly to the adjusting stud. This intermediary structure resolves the contradiction by providing a separate load-bearing path.
2Reliability
If the L-shaped fixed clamping block is used to clamp the lower edge of the drum frame, then the clamping function is achieved, but the weights of musical instruments or auxiliary devices directly act on the adjusting stud, causing noise interference
Solution Approach 1:
The structure is segmented to separate the clamping function (performed by clamping blocks) from the load-bearing function (performed by the locking and connecting structure). This segmentation prevents weight-induced noise by eliminating direct contact between the adjusting stud and the weights of musical instruments or auxiliary devices.
Solution Approach 2:
The locking and connecting structure acts as an intermediary that bears the weights of musical instruments or auxiliary devices, preventing these weights from directly acting on the adjusting stud and thereby eliminating noise interference while maintaining clamping stability.
3Reliability
If the conventional clamping structure is used, then the drum frame can be clamped, but the assembly and disassembly process is time-consuming and not rapid
Solution Approach 1:
The movable clamping block is designed to rotate relative to the fixed clamping block, enabling dynamic adjustment and rapid engagement. The screw locking mechanism provides quick locking and unlocking actions, significantly reducing assembly and disassembly time while maintaining secure clamping.
Solution Approach 2:
The screw locking mechanism allows for rapid parameter changes in the clamping state through simple rotational motion. By changing the rotational parameter of the screw locking piece, the clamping force can be quickly adjusted or released, enabling rapid assembly and disassembly while ensuring clamping security.
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 solution ensures smooth operation of the screw locking piece, reduces noise interference, and facilitates rapid assembly and disassembly of the drum frame, while allowing for secure clamping and easy arrangement of additional instruments or devices.
Implementation Method 1
the screw locking piece passes through the driving part in a screw locking manner and abuts against the abutting curved surface of the lower clamping piece, the spiral rotation of the screw locking piece can drive the driving part to move
Implementation Method 2
the upper clamping piece and the lower clamping piece are pivotally connected with each other through a rotary shaft
