Dynamic Receiving Time Limit for Perishable Goods Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unattended delivery of perishable goods can lead to early damage due to prolonged storage at transport destinations, as existing systems lack the ability to set appropriate receiving time limits based on environmental conditions.
Innovation Solution
A transport system that includes an unmanned mobile body equipped with sensors to acquire environmental information at the transport destination, determining a receiving time limit for each load type based on its characteristics and the environmental conditions, and notifying recipients of these limits, with controls for re-routing or collection if the load is not received within the set time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If unattended delivery is used to reduce work cost and enable non-face-to-face receipt, then productivity and convenience are improved, but the load may be damaged earlier due to prolonged storage at the transport destination
Solution Approach 1:
The system dynamically changes the receiving time limit parameter based on environmental conditions (temperature, humidity) and load characteristics (freshness requirements). By adjusting this temporal parameter according to real-time environmental data, the system optimizes the balance between unattended delivery convenience and load preservation, preventing both premature retrieval and excessive storage duration.
2Ease of operation
If a fixed receiving time limit is set for all loads, then the system is simple to operate, but it cannot adapt to different environmental conditions and load types
Solution Approach 1:
The receiving time limit is transformed from a static fixed value to a dynamic parameter that automatically adjusts based on environmental conditions and load characteristics. The system continuously monitors temperature, humidity, and other environmental factors, then dynamically recalculates the appropriate receiving time limit, enabling adaptation to varying conditions without requiring manual intervention.
Solution Approach 2:
The system performs self-adjustment of the receiving time limit by automatically acquiring environmental information, analyzing load characteristics, and determining the optimal time limit without human intervention. This self-service capability maintains ease of operation while achieving high adaptability to different environments and load types.
3Reliability
If environmental sensing is implemented to determine appropriate receiving time limits, then load reliability is improved, but device complexity increases
Solution Approach 1:
The mobile body performing unattended delivery is equipped with multi-functional capabilities including environmental sensing, data processing, and automatic time limit determination. By integrating these diverse functions into a single universal system, the patent reduces the need for separate dedicated devices, thereby limiting the increase in overall system complexity while achieving reliable load protection.
