Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional acoustic cymbals are used, then realistic sound quality is achieved, but device complexity and lack of electronic control are issues
Solution Approach 1:
The patent uses a simulated cymbal that copies the visual appearance and basic function of a traditional cymbal, but replaces the acoustic sound generation with electronic sound synthesis. The simulated cymbal is struck by drumsticks to trigger electronic sensors, which then generate realistic cymbal sounds through speakers, combining the simplicity of a visual copy with the control capabilities of electronic systems.
Solution Approach 2:
The patent replaces the mechanical acoustic system of traditional cymbals with an electronic system. Instead of relying on the physical vibration and acoustic resonance of metal cymbals, the invention uses sensors to detect strikes on the simulated cymbal and electronically generates the corresponding sounds through amplification and speaker output, substituting mechanical acoustics with electronic sound generation.
2Adaptability or versatility
If electronic sensors are added to detect cymbal movement, then dynamic control is improved, but measurement precision and tactile feedback quality deteriorate
Solution Approach 1:
The patent introduces a magnetic field as an intermediary between the movable cymbal assembly and the stationary housing. A magnet is attached to the movable assembly and a Hall effect sensor is mounted on the stationary housing. The magnetic field serves as a non-contact intermediary that enables precise measurement of position and velocity without mechanical interference, maintaining both dynamic control and measurement precision.
Solution Approach 2:
The patent replaces direct mechanical contact sensors with a magnetic field-based sensing system. The Hall effect sensor detects changes in the magnetic field caused by the movement of the magnet attached to the cymbal assembly, providing precise positional and velocity information without physical contact. This substitution eliminates mechanical wear and interference while maintaining high measurement precision.
3Ease of operation
If a Hall effect sensor and magnet system is implemented, then tactile feedback and dynamic range are improved, but device complexity increases
Solution Approach 1:
The magnetic field acts as an intermediary that enables tactile feedback and dynamic control without requiring complex mechanical linkages. The Hall effect sensor detects the magnetic field position to determine cymbal velocity and position, providing tactile feedback information that is then used by the electronic system to generate appropriate sounds, simplifying the overall control mechanism.
Solution Approach 2:
The magnetic field and Hall effect sensor system serves multiple functions simultaneously: it measures position, measures velocity, provides tactile feedback information, and triggers sound generation. This multi-functionality reduces the need for separate sensors and control mechanisms, thereby reducing overall device complexity despite the advanced sensing technology used.

AI summary
An electronic hi-hat system having a movable upper housing separated from a stationary lower housing by a spring, with the upper housing having a simulated cymbal attached thereto. The upper housing and simulated cymbal connect through a central vertical rod to a lower foot pedal, with the entire structure supported by a stand on which the lower housing mounts. The lower housing has a Hall effect sensor mounted thereon, and the upper housing has a permanent magnet aligned with and arranged to reciprocate vertically alongside the Hall effect sensor. The position of the magnet on the movable upper housing, and thus the simulated cymbal, is detected by the Hall effect sensor which combines with signals generated by a sound pickup attached to the simulated cymbal that senses the cymbal being struck by a drumstick, the result being transmitted, processed, and amplified into simulated high-hat cymbal sounds
