Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing monitoring systems are used to protect valuable items, then monitoring capability is provided, but the systems are too large and heavy to be attached without affecting the musical performance of the instrument
Solution Approach 1:
The monitoring system is divided into separate functional modules: environmental sensors (temperature, humidity), motion detection sensors, wireless communication module, and microprocessor, all integrated into a compact unit that can be attached to the instrument case without affecting the instrument itself
Solution Approach 2:
Multiple sensing functions and communication capabilities are merged into a single integrated module that combines environmental monitoring, motion detection, wireless transmission, and data processing in one compact unit
2Reliability
If existing monitoring systems are used to protect individual items in stores or museums, then protection capability is provided, but the systems are not cost-effective for individual protection
Solution Approach 1:
The system uses cost-effective sensors and microelectronic components that can be mass-produced at low cost, making the system economically viable for attaching to individual items in retail stores or museums rather than requiring expensive specialized equipment
Solution Approach 2:
The monitoring module is designed with universal applicability to protect various types of valuable items including musical instruments, retail goods, and museum artifacts, providing multi-functional protection capabilities through a single system design
3Loss of information
If existing monitoring systems are used, then environmental monitoring is provided, but motion detection capabilities are lacking
Solution Approach 1:
The system integrates both environmental monitoring (temperature, humidity sensors) and motion detection (accelerometer) capabilities into a single multi-functional module that can detect various types of events including environmental changes, motion, shock, and drop conditions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective monitoring and protection of valuable items by detecting environmental and motion-related data, sending alerts, and storing data for analysis, while being lightweight and inexpensive enough for individual attachment, with adaptive communication and energy-saving features.
Implementation Method 1
an accelerometer; a wireless communications module; and a controller operatively coupled to the humidity sensor, the accelerometer, and the wireless communications module
Implementation Method 2
a humidity sensor; sampling, using the humidity sensor and in the active state, a relative humidity of an environment of the mobile data collection module
Data Source
AI summary
The invention integrates hardware and software for sensing, communications, data storage and control into a protection module that is sufficiently small and inexpensive to be attached directly to individual objects, such as musical instruments, and the inventory of stores and museums. Sensors monitor environmental factors, such as temperature and humidity, and accelerometers alert owners to unwanted motion, such as theft or misuse. Sensed data is stored locally and transmitted wirelessly to nonproprietary data receivers, such as smart phones or tablets that generate alerts. In some embodiments the data is forwarded to cloud servers for storage and analysis. Bluetooth communication between the attached module and the data receiver allows large spaces, such as stores and showrooms containing many attached modules to be protected. In some embodiments accelerometers enable finger-tap-controlled recording of musical performance and tuning of the instrument relative to tonal frequencies stored in the module.
