Monitoring Device With Flexible Flange and Recessed Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring devices for environmental conditions and object exposure lack efficient battery management, leading to bulkiness and potential damage from prolonged activation, and struggle to determine the accountability of damage to goods during storage, transit, or after receipt.
Innovation Solution
A monitoring device with a flexible flange portion on a substrate and a recessed circuit carrier design that accommodates a coin cell battery, allowing for compactness and preventing deformation, along with sensors for environmental and force measurements, and an RFID transceiver for data logging and reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the processor and indicator are activated over a long period of time to monitor environmental conditions, then the monitoring capability is improved, but the battery capacity requirement increases leading to bulkiness
Solution Approach 1:
The processor is configured to periodically poll the sensors rather than continuously monitoring, activating only at intervals to reduce power consumption. This periodic operation enables the device to maintain monitoring capability over extended periods while using a smaller, more compact battery, thus resolving the contradiction between monitoring duration and device volume.
2Duration of action of stationary object
If a battery with sufficient capacity is used to power the processor and indicator for extended periods, then the monitoring duration is improved, but the device becomes bulky and requires additional accommodating features
Solution Approach 1:
By implementing periodic polling of sensors rather than continuous operation, the power consumption is significantly reduced. This allows the use of a compact battery with sufficient capacity for extended operation without requiring the device to be bulky or incorporate complex battery accommodating features.
Solution Approach 2:
The system changes the operational parameters by reducing the duty cycle of the processor and indicator, activating them only periodically rather than continuously. This parameter change enables extended monitoring duration with a smaller battery, simplifying the overall device structure.
3Volume of moving object
If the monitoring device is made compact to reduce bulkiness, then the device portability is improved, but the battery capacity may be insufficient for prolonged activation
Solution Approach 1:
The periodic polling mechanism reduces power consumption enough to enable the use of a compact battery, allowing the device to maintain a small volume while still achieving prolonged monitoring duration through efficient intermittent operation rather than continuous activation.
