Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing musical instruments, particularly drum kits, are expensive and bulky, making them inaccessible to ordinary people, and prior art lacks a wearable solution with a palm sensor for generating bass inputs or striking surfaces to produce electronic percussion sounds effectively.
Innovation Solution
A wearable drum trigger system using donnable garments with pressure and trigger sensors that mimic hand movements to create music, allowing users to play drums without the cost and logistics of traditional drum kits, incorporating piezo pressure sensors, tactile switches, and wireless connectivity for mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional acoustic drum kits are used, then music creation capability is achieved, but cost and bulk make them inaccessible to ordinary people
Solution Approach 1:
The patent extracts only the essential sensing function from a complete drum kit, using a single wearable sensor unit that can detect hand movements and convert them to drum sounds, eliminating the need for bulky acoustic drums and multiple components
Solution Approach 2:
The patent creates a virtual copy of the drum kit experience through software synthesis, where hand movements are translated into electronic drum sounds via a wearable sensor, providing the full drum kit functionality without the physical bulk
2Adaptability or versatility
If prior art electronic gloves with palm sensors are used, then data entry functions are achieved, but they cannot generate electronic signals by striking surfaces for bass inputs
Solution Approach 1:
The patent makes the palm sensor dynamic by enabling it to detect both static data entry inputs and dynamic striking motions, allowing the same sensor to function for different purposes depending on the user's action
Solution Approach 2:
The patent makes the palm sensor universal by designing it to serve multiple functions: traditional data entry tasks and new percussion striking functions, allowing one sensor to replace multiple specialized devices
3Ease of operation
If wearable drum triggers with multiple sensors are used, then music creation mobility is improved, but device complexity increases
Solution Approach 1:
The patent segments the drum kit functionality into separate wearable modules, with each sensor handling a specific drum or percussion element, allowing modular configuration and reduced overall complexity
Solution Approach 2:
The patent uses a universal sensor platform that can detect various types of hand movements and map them to different drum sounds, reducing the need for multiple specialized sensors
