Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional delivery service systems lack the ability to track the internal state and external events of delivery items during transportation, leading to uncertainties in item condition upon receipt and frequent disputes over responsibility.
Innovation Solution
A transportation data logging device attached to the internal surface of an accommodation body, equipped with sensors to monitor internal state information and external events, a memory unit to store data, a communication unit for wireless transmission, and a power supply unit, allowing real-time tracking and monitoring of item conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional delivery service systems are used to track items, then location information can be checked through the Internet, but information on the state of the item during delivery process cannot be checked
Solution Approach 1:
The data logging device is nested inside the accommodation body (delivery box), with sensors, memory unit, and communication unit integrated within the confined space of the delivery container. This nesting approach enables comprehensive item state monitoring without requiring external tracking infrastructure, thereby preventing information loss while avoiding excessive system complexity.
Solution Approach 2:
The accommodation body is equipped with self-contained sensing units, memory units, and communication units that autonomously monitor and record item state information during delivery. The system performs self-diagnosis and self-reporting of delivery conditions, eliminating the need for external monitoring equipment and reducing overall system complexity while preventing information loss.
2Reliability
If multiple sensors are added to monitor internal state and external events, then item condition tracking is improved, but device complexity increases
Solution Approach 1:
The sensing unit is designed with multi-functional sensors that can detect multiple parameters (temperature, humidity, impact, light) using integrated sensor modules. This universal sensing approach enables comprehensive item condition verification through a single compact sensing unit, thereby improving reliability without proportionally increasing device complexity.
Solution Approach 2:
Multiple sensing functions (temperature sensing, humidity sensing, impact detection, light detection) are merged into a single integrated sensing unit within the accommodation body. This consolidation combines multiple monitoring capabilities into one compact module, enhancing item condition verification reliability while minimizing the increase in device complexity through functional integration.
3Loss of information
If real-time monitoring is implemented during transportation, then transportation environment verification is enabled, but power consumption increases
Solution Approach 1:
The sensing unit operates by periodically sampling transportation environment parameters (temperature, humidity, impact) at predetermined time intervals rather than continuous monitoring. This periodic measurement approach enables sufficient transportation environment verification while significantly reducing power supply consumption compared to real-time continuous monitoring.
Solution Approach 2:
The memory unit is pre-configured with sufficient storage capacity to record all sensing data throughout the entire delivery process. This preliminary preparation allows the system to collect comprehensive transportation environment data during delivery without requiring continuous power-intensive data transmission, reducing power consumption while preventing information loss.
