Electronic Percussion Head Groove Attachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic percussion systems, such as electronic drums, have complex structures and mechanisms that complicate the attachment and removal of the drum head during both assembly and maintenance, making it difficult to configure and maintain a head with rigidity.
Innovation Solution
The electronic percussion system features a frame with groove-shaped holding grooves, where the head is securely engaged via a first holding groove and further stabilized by a second holding groove with greater depth, allowing for easy mounting and removal, and includes a head fixing body made of an elastic material to prevent the head from dropping, along with a buffer to reduce unusual sounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the head is fixed to the frame by fastening screws, then the head can be securely attached, but the structure becomes complex and the attachment/removal process becomes complicated
Solution Approach 1:
The holding groove is divided into two distinct segments: a first holding groove for initial engagement and a second holding groove for final securing. This segmentation allows the head to be attached and removed in a simplified two-step process without requiring complex screw fastening mechanisms, thus reducing structural complexity while maintaining secure attachment.
Solution Approach 2:
The holding groove acts as an intermediary structure between the head and the frame. Instead of directly fastening the head to the frame with screws, the holding groove serves as a mediating element that secures the head through its groove shape, simplifying the overall attachment mechanism while ensuring reliable fixation.
2Reliability
If the head is fixed by fastening screws, then the attachment is secure, but the attachment and removal processes become time-consuming
Solution Approach 1:
The attachment process is segmented into two quick steps: inserting the head into the first holding groove for engagement, and then securing it with the second holding groove. This segmented approach eliminates the time-consuming process of screw fastening while maintaining reliable attachment, significantly reducing assembly and maintenance time.
Solution Approach 2:
The holding grooves are pre-formed in the frame structure, allowing the head to be directly engaged without requiring preliminary fastening operations. The first holding groove is designed to automatically engage the head upon insertion, and the second holding groove is ready to secure it, eliminating the need for time-consuming screw fastening procedures.
3Device complexity
If a single holding groove is used, then the structure is simple, but the head may drop or become unstable
Solution Approach 1:
The holding structure is segmented into two functional grooves: the first holding groove provides initial engagement and positioning, while the second holding groove provides additional securing. This segmentation enhances head stability and prevents dropping without significantly increasing structural complexity, as both grooves are integrated into the frame.
Solution Approach 2:
The two holding grooves are nested within the frame structure, with the second holding groove positioned to work in conjunction with the first. This nested arrangement provides enhanced stability and prevention of head dropping while maintaining a compact and relatively simple overall structure.

AI summary
An electronic percussion includes: a plate-shaped head constituting a struck surface beaten by a player; a frame formed into an annular frame shape surrounding an outer edge of the head, the frame holding the head via the outer edge; and a hitting sensor configured to detect at least one of a vibration and a pressure generated by hitting of the head to output an electrical signal. The frame includes: a first holding groove formed into a groove shape at an inner surface of the frame, the outer edge of the head being engaged with the first holding groove such that the head is held; and a second holding groove formed into a groove shape at a position adjacent to and along the first holding groove such that the second holding groove communicates with the first holding groove, the second holding groove having a depth deeper than a depth of the first holding groove.
