Drum Coupling Assembly for Secure Percussion Object Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drum coupling systems fail to securely attach and easily reposition percussive effect objects on a drumhead without damaging the drum or disrupting its vibration, due to issues with adhesives and limited positioning of accessories.
Innovation Solution
A drum coupling assembly featuring a first and second clamp coupled to the drum hoop with an elastic cord extending between them, allowing for secure attachment and easy repositioning of objects by holding a portion of the cord between the drum hoop and head, preventing undesired movement and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesives are used to fasten objects to drumhead, then objects can be securely attached, but repositioning becomes difficult and drumhead may get damaged
Solution Approach 1:
The attachment system is divided into separate components: a clamp that attaches to the drum rim and an elastic cord that contacts the object. This segmentation allows the object to be released by simply opening the clamp without affecting the drumhead, resolving the contradiction between secure attachment and easy repositioning.
Solution Approach 2:
An elastic cord is introduced as an intermediary between the clamp and the object. The cord transmits the holding force while allowing the object to be easily positioned and repositioned by adjusting the cord tension, maintaining both attachment security and repositioning ease.
2Adaptability or versatility
If adhesives are used to dampen drum tone, then tone control is achieved, but full vibration and resonance are impeded
Solution Approach 1:
Instead of applying adhesive over large areas of the drumhead, the elastic cord provides localized contact only where needed to dampen specific tones. This localized approach allows tone control while preserving the overall vibration and resonance characteristics of the drumhead.
3Reliability
If brackets or mounts are used to attach accessories, then accessories can stay in place, but positioning is limited to one type of effect/use
Solution Approach 1:
The elastic cord provides a dynamic attachment system where the object can be easily moved to different positions by adjusting the cord length and tension. This dynamic mechanism maintains position stability during playing while allowing flexible repositioning for different effects and uses.
Solution Approach 2:
The clamp and elastic cord system can accommodate various types of objects and accessories at different positions on the drum, making it a universal attachment solution that supports multiple effects and uses rather than being limited to a single function.
4Measurement precision
If objects are placed against drumhead at certain location and pressure, then desired tone is produced, but objects move to undesired positions due to vibrations and playing
Solution Approach 1:
The elastic cord is pre-tensioned to apply continuous pressure on the object, holding it firmly at the desired position before playing begins. This preliminary action ensures the object maintains its precise position and produces the desired tone throughout playing, preventing movement due to vibrations and strikes.
