Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for securing and controlling access to temperature-controlled containers are inadequate for maintaining temperature-sensitive items, especially in remote locations with harsh climates, leading to potential spoilage and safety issues.
Innovation Solution
A locking system for temperature-controlled containers that includes a temperature sensor, a controller, and a locking device, which locks the container barrier when the temperature exceeds a predetermined threshold, ensuring access is restricted until the temperature is within the required range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional locking systems are used for temperature-controlled containers, then access control is provided, but temperature monitoring and automatic locking to prevent spoilage is not achieved
Solution Approach 1:
The patent combines the locking device with temperature monitoring and control functions into an integrated system. The controller receives temperature data from sensors and automatically activates the locking device when temperature thresholds are exceeded, merging security and temperature management into a single coordinated system that improves reliability without proportionally increasing complexity.
Solution Approach 2:
The system implements feedback control by continuously monitoring temperature through sensors and using this information to control the locking device state. When temperature rises above the threshold, the controller receives feedback and automatically locks the barrier, creating a closed-loop system that maintains temperature integrity through automated response.
2Reliability
If manual access control is used, then simple operation is maintained, but temperature-sensitive items may be accessed when temperature is outside safe range
Solution Approach 1:
The locking system operates autonomously by self-monitoring temperature conditions and self-activating the locking mechanism when temperature thresholds are violated. The controller automatically processes temperature data and controls the locking device without requiring human intervention, ensuring food safety through automated decision-making while maintaining simple user interaction.
Solution Approach 2:
The system uses temperature feedback to automatically control access. The controller continuously receives temperature readings and automatically locks the barrier when readings exceed safe thresholds, eliminating the need for manual temperature checking and access decisions while ensuring food safety compliance.
3Reliability
If no automatic locking mechanism is implemented, then device complexity is reduced, but temperature-sensitive items cannot be protected from access during temperature excursions
Solution Approach 1:
The patent replaces manual mechanical locking operations with an automated electromechanical system. The locking device is controlled electronically through a controller that processes temperature sensor data, substituting automatic electronic control for manual mechanical operation. This achieves reliable temperature-based protection while keeping the interface simple through automated decision-making.
Solution Approach 2:
The system performs automatic temperature monitoring and locking activation without requiring manual intervention. The controller autonomously processes temperature data and activates the locking device when needed, enabling reliable temperature control through self-service operation that minimizes the need for complex user interactions.

AI summary
A locking system for a temperature-controlled container is provided. The container has an interior and a barrier having an open position allowing access to the interior of the container and a closed position blocking access to the interior of the container. The locking system includes a temperature sensor for sensing a temperature within the container; a locking device coupled to the barrier to lock the barrier in the closed position; and a controller in communication with the locking device and the temperature sensor. The controller receives the sensed temperature from the temperature sensor and controls the locking device based on the sensed temperature. The controller is configured to control the locking device to lock the barrier in the closed position when the sensed temperature rises above a predetermined threshold temperature.
