Contactless delivery locker system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a contactless delivery system that enhances the safety and confidence of food delivery by ensuring the food remains sealed and disinfected from preparation to consumption, particularly in the context of the COVID-19 crisis where maintaining food safety and quality during transportation is critical.
Innovation Solution
A smart contactless delivery locker system with wireless communication capabilities, UV disinfecting features, and environmental insulation (heating/cooling) that allows secure, touchless opening and monitoring of food status, ensuring the food remains sealed and disinfected throughout the delivery process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contactless delivery system is implemented, then customer safety and food security are improved, but system complexity and infrastructure requirements increase
Solution Approach 1:
An automated locker system serves as an intermediary between the delivery driver and the customer. The locker receives the order via wireless communication, maintains it in a controlled environment with UV disinfection, and releases it only upon verified customer pickup. This eliminates direct contact while ensuring food safety through automated processes.
Solution Approach 2:
The locker system operates autonomously without human intervention for critical safety functions. It automatically disinfects food containers with UV light, monitors temperature conditions, tracks door openings, and manages the delivery workflow through wireless communication. This self-service capability ensures consistent food safety standards while reducing system operational complexity.
2Reliability
If UV disinfecting and environmental controls are added, then food quality and safety are improved, but energy consumption and device complexity increase
Solution Approach 1:
The UV disinfection system operates periodically rather than continuously - activating when the locker receives a new order and when the door is opened. Environmental controls (heating/cooling) are activated only when the locker is occupied with food, reducing energy consumption while maintaining food quality and safety standards.
Solution Approach 2:
Environmental controls and UV disinfection are applied locally within the locker compartment only when needed, rather than throughout the entire system. This targeted approach maintains food quality in the specific area where food is stored while minimizing overall energy consumption.
3Loss of information
If wireless communication and monitoring features are integrated, then customer confidence and food security are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The locker system integrates multiple functions into a single device: wireless communication for order reception and customer notification, UV disinfection for food safety, environmental controls for temperature management, and door monitoring for security tracking. This multi-functionality reduces the need for separate systems while maintaining comprehensive food status monitoring.
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 system provides enhanced safety and confidence for customers by maintaining the integrity and quality of food from preparation to consumption, reducing the risk of contamination and ensuring food is kept within safe temperature ranges during transport.
Implementation Method 1
a UV light source to irradiate the food container
Implementation Method 2
an insulating material surrounding the interior surface of the locker module

AI summary
A contactless delivery locker may have a locker housing with a locker door fitted to the locker housing. A disinfecting system may be arranged to disinfect the locker content and a remotely actuable lock may be arranged to secure the locker door in a closed position and actuable to release the locker door. A controller associated with the lock may be configured to actuate the lock and a wireless interface may be connected to the controller and configured to receive a command to actuate the lock to release the locker door. The controller may operate to control actuation of the lock to release the locker door upon detection of a command to actuate the lock and release the locker door. The controller may be configured to report lock status information to a user to confirm if a locker has been opened after completion of a disinfecting cycle.
