Food delivery assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food delivery devices lack effective mechanisms to keep hot food items secure and fresh during transportation, and they often require manual locks that can be inconvenient to use.
Innovation Solution
A thermally insulated delivery device with a locking unit that is wirelessly connected to the recipient's personal electronic device, allowing for secure and convenient access to the hot food item.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual lock mechanism is used to secure the food container, then the food item is secure during delivery, but the ease of operation deteriorates due to inconvenient locking and unlocking processes
Solution Approach 1:
The patent replaces the traditional mechanical lock system with an electronic locking mechanism controlled by a microcontroller. The lock is actuated electronically through a motor driver circuit rather than manual mechanical operation, enabling remote control via wireless communication while maintaining secure locking functionality.
Solution Approach 2:
The system automatically locks the food container when the lid is closed and automatically unlocks it when the recipient enters the correct PIN code through the mobile application. This eliminates the need for manual locking operations by the delivery person and enables convenient self-service unlocking by the recipient.
2Reliability
If the locking unit is continuously engaged to ensure food security, then the food item remains secure, but the ease of operation worsens due to difficulty in accessing food when needed
Solution Approach 1:
The locking mechanism transitions from a static continuously engaged state to a dynamic state that can be remotely controlled. The lock can be engaged or disengaged on demand through wireless communication between the mobile application and the microcontroller, allowing the recipient to access food when needed while maintaining security during delivery.
Solution Approach 2:
The wireless communication system acts as an intermediary between the recipient and the locking mechanism. The mobile application sends unlock commands through wireless transmission to the microcontroller, which then actuates the motor driver to disengage the lock, providing convenient remote access without physical manipulation of the lock.
3Temperature
If thermal insulation is added to maintain food temperature, then the food remains hot during delivery, but the device complexity increases due to additional insulation layers and components
Solution Approach 1:
The patent utilizes the lid itself as a thermal insulation barrier by integrating insulation material into the lid structure. This thin film approach provides effective thermal protection while avoiding the complexity of adding multiple thick insulation layers to the food container.
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
The device effectively maintains the temperature of hot food items during delivery and ensures secure access, preventing unauthorized access and food spoilage.
Implementation Method 1
a box that is comprised of a thermally insulating material thereby facilitating the box to inhibit heated items from cooling when the heated items are placed in the box

AI summary
A food delivery assembly includes a box that is comprised of a thermally insulating material thereby facilitating the box to inhibit heated items from cooling when the heated items are placed in the box. A lid is movably coupled to the box for opening and closing the box and to inhibit the heated items from cooling when the heated items are placed in the box. An engagement is coupled to the lid and a locking unit is attached to the box. The locking unit releasably engages the engagement when the lid is close. The locking unit is in wireless communication with a personal electronic device possessed by a recipient of the food delivery. The locking unit is actuated into a disengaging condition when a pin is communicated from the personal electronic device to the locking unit to access the hot food item.
