Solution Overview
Problem
Existing electronic percussion instruments face challenges in accurately detecting the location of percussion strokes with high precision while maintaining cost-effectiveness due to complex mechanical and electrical assembly requirements, leading to increased production costs.
Innovation Solution
The design incorporates a body with integrated support structures and a peripheral sensor system, utilizing flexible rising elements and a peripheral carrier to transmit vibrations from the drumhead to sensors, along with a flexible circuit board to reduce electrical connections and simplify assembly, thereby minimizing production labor and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are placed on the periphery of the drumhead for accurate positional detection, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple peripheral sensors onto a single peripheral carrier board, which is then mounted on the drum shell. This merging approach maintains the measurement precision of multiple sensors while reducing assembly complexity by treating the sensor array as a single integrated unit rather than individually mounting each sensor.
Solution Approach 2:
The peripheral carrier acts as an intermediary component that holds multiple sensors and provides a standardized mounting interface to the drum shell. This mediator simplifies the assembly process by enabling bulk installation of sensors through a single mounting operation rather than individual sensor placement.
2Measurement precision
If multiple sensors and supporting structures are used for faithful positional detection, then measurement precision is improved, but manufacturing cost increases
Solution Approach 1:
By integrating multiple sensors onto a single peripheral carrier board, the patent reduces the total number of separate components that need to be manufactured and assembled. This merging strategy maintains measurement precision while lowering manufacturing costs through reduced part counts and simplified production processes.
Solution Approach 2:
The peripheral carrier serves multiple functions: it holds multiple sensors, provides structural support, and interfaces with the drum shell through standardized mounting points. This multi-functionality reduces the need for separate supporting structures, thereby reducing overall manufacturing cost while maintaining detection accuracy.
3Measurement precision
If a separate drum shell with additional interior parts is used for sensor mounting, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent integrates the sensor mounting function directly into the existing drum shell structure through the peripheral carrier, eliminating the need for separate interior mounting parts. This merging approach maintains measurement precision while reducing mechanical assembly complexity by avoiding additional interior components.
