Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of pad devices is increased or their locations are changed, then the functionality and versatility of the electronic drum set is improved, but the cable management becomes more troublesome and the setup complexity increases
Solution Approach 1:
The patent extracts the cable connection function from the system by introducing wireless communication between pad devices and the sound generating device. Each pad device is equipped with a wireless transmitting section, and the sound generating device has a wireless receiving section, completely eliminating the need for physical cable connections. This resolves the cable management complexity while allowing flexible addition and repositioning of pad devices.
2Adaptability or versatility
If the cable length is made adequate to reach all pad devices, then the installation flexibility is improved, but the excess cable handling becomes burdensome and the appearance deteriorates
Solution Approach 1:
The patent removes the cable component entirely from the system by implementing wireless communication. The transmitting section in each pad device and the receiving section in the sound generating device enable data transmission without physical connections, eliminating issues of excess cable handling and appearance deterioration while maintaining full installation flexibility.
3Shape
If the cable length is made short to maintain good appearance, then the aesthetic quality is improved, but the radius of installation of pad devices is limited
Solution Approach 1:
By extracting the physical cable connection and replacing it with wireless communication, the patent eliminates the trade-off between cable length and installation radius. The wireless transmitting and receiving sections enable pad devices to be placed anywhere within the wireless communication range, providing unrestricted installation flexibility while maintaining a clean appearance without visible cables.
4Adaptability or versatility
If multiple cables are used to connect multiple pad devices, then the connectivity is improved, but the weight of the system increases and wrong connections become more likely
Solution Approach 1:
The patent removes the cable weight from the system by implementing wireless communication. The transmitting section in each pad device and the receiving section in the sound generating device eliminate the need for physical cables, reducing the overall system weight while maintaining full connectivity among multiple pad devices through wireless data transmission.
5Measurement precision
If manual setup of cable connections and sound image localization is performed, then the setup precision is improved, but the setup time and operational complexity increase
Solution Approach 1:
The patent implements automatic sound image localization by having the sound generating device receive location information from each pad device's transmitting section and automatically determine the appropriate sound image localization settings. This self-service approach eliminates the need for manual setup while maintaining accurate sound image localization, significantly reducing setup time and operational complexity.
Solution Approach 2:
The system uses feedback from the pad device locations to automatically adjust sound image localization. The sound generating device receives location data from each pad device and uses this feedback to automatically configure the appropriate audio output settings, eliminating manual setup while ensuring accurate sound positioning.

AI summary
Each of a plurality of pad devices that can be moved independent of each other includes: a sensor section for detecting a strike; and a transmitting section for transmitting operation information according to an output of the sensor section with wireless communication. A receiving section is provided in connection with a sound generating device to receive the operation information transmitted from each of the pad devices with wireless communication. The sound generating device generates a musical tone signal in accordance with the received operation information. A pad location detecting section detects a location of each of the pad devices. The sound generating device carries out tone generation control, for example, sound image localization control, for the musical tone signal generated in correspondence with each of the pad devices in accordance with the location of each of the pad devices detected by the pad location detecting section.
