Building Controller Lock Box With Hinged Cover and Mounting Back Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building automation systems, such as HVAC controllers, lack effective protection against tampering, as current lock boxes do not provide a simple and efficient method for mounting and securing these devices, potentially allowing unauthorized access.
Innovation Solution
A lock box design featuring a back plate with mounting features for securing a wall mountable connector and a hingedly coupled front cover that can be locked in place, providing secure access to the building controller while allowing easy installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock box is used to protect the building controller, then protection against tampering is improved, but mounting and securing the device becomes more complex
Solution Approach 1:
The lock box is divided into a back plate and a front cover that can be separately mounted and assembled. The back plate includes mounting features for securing to a wall, while the front cover can be attached and locked independently, simplifying the overall mounting process while maintaining security.
Solution Approach 2:
The back plate is pre-configured with mounting features such as mounting holes and engagement structures before the front cover is attached. This preliminary preparation of mounting features on the back plate simplifies the installation process and reduces on-site complexity.
2Reliability
If the front cover is locked in place to prevent unauthorized access, then security is improved, but ease of operation for authorized users deteriorates
Solution Approach 1:
The front cover is designed to be movable between a closed locked position for security and an open position for authorized access. This dynamic design allows the cover to transition between protective and accessible states, maintaining both security and ease of operation for authorized users.
Solution Approach 2:
A locking mechanism serves as an intermediary between the front cover and the back plate, providing controlled access. The lock allows authorized users to open the cover while preventing unauthorized access, thus maintaining security without permanently restricting access.
3Reliability
If mounting features are added to the back plate to secure the wall mountable connector, then reliability of connection is improved, but device complexity increases
Solution Approach 1:
The mounting features for securing the wall mountable connector are integrated directly into the back plate structure. By combining the mounting functions with the existing back plate, the design avoids adding separate complex mounting mechanisms, thus improving connection reliability while minimizing increases in overall device complexity.

AI summary
Lock boxes may be used to protect a building controller from tampering. In some cases, a lock box may include a back plate that is configured to be mounted to a wall or a junction box and a front cover that may be secured to the back plate and locked in place. In some cases, the back plate may be configured to help secure a building controller thereto. In some cases, the back plate may be configured to secure a wall mountable connector to which the building controller may be secured. In some instances, the back plate may include mounting features that can engage corresponding mounting features of the wall mountable connector in order to secure the wall mountable connector to the back plate of the lock box.
