Fixed-View Camera Housing for Medication Monitoring and Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surveillance cameras are difficult to integrate into existing medication management systems with a proper placement and orientation to capture interactions with prescription medications, and they can inadvertently capture sensitive information in care settings.
Innovation Solution
A surveillance camera with a deterministic field of view is mounted on medical devices like dispensing cabinets, using a housing that maintains the camera in a fixed position and orientation, equipped with heat sinks for cooling, and includes features for tamper detection to prevent unauthorized removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the surveillance camera is mounted on medical devices to capture interactions with medications, then the ability to detect diversion and anomalous behavior is improved, but the risk of capturing sensitive information in care settings increases
Solution Approach 1:
The camera is positioned to capture only specific local areas where medication interactions occur, such as the dispensing cabinet area, rather than providing broad coverage of the entire care setting. This localized surveillance approach enables detection of diversion while minimizing capture of sensitive information in other areas.
Solution Approach 2:
The system uses motion detection to dynamically activate the camera only when movement is detected in the field of view, such as when a clinician approaches the dispensing cabinet. This dynamic operation ensures the camera captures relevant interaction events while remaining inactive during other times to avoid capturing sensitive information.
2Area of stationary object
If the camera position is made adjustable to capture different areas, then the field of view coverage is improved, but the complexity of installation and operation increases
Solution Approach 1:
The surveillance system is divided into multiple fixed camera units, each positioned to monitor specific areas or zones within the medical device. Instead of one complex adjustable camera, multiple simple fixed cameras cover different areas, reducing installation complexity while maintaining comprehensive coverage.
Solution Approach 2:
The camera housing is pre-configured with the camera positioned at optimal angles and orientations during manufacturing. The camera is pre-oriented to capture the intended area of interest, eliminating the need for complex installation adjustments and ensuring proper field of view coverage from the outset.
3Ease of operation
If the camera is mounted in a fixed position to simplify installation, then the ease of operation is improved, but the flexibility to adapt to different mounting locations is reduced
Solution Approach 1:
The camera housing is designed with universal mounting features that can be attached to various types of medical devices and surfaces using standardized mounting mechanisms. The housing includes features such as adjustable mounting brackets and compatible fastening systems that enable installation on different device types while maintaining the fixed camera position for simplified operation.

AI summary
A camera assembly may include a camera and one or more heat sinks configured to dissipate heat generated by the camera. The heat sinks being in thermal contact with a printed circuit board including the camera. A housing of the camera assembly may be configured to maintain the camera in a fixed position while the camera assembly is mounted on a medical device such as a dispensing cabinet. The camera in the fixed position may have a deterministic field of view that includes a first area in which interactions with the medical device and adjacent medical devices occurs or is expected to occur. The deterministic field of view of the camera may further exclude a second area where surveillance is unsuitable, prohibited, and/or unnecessary. Images captured by the camera may be analyzed to detect anomalous behavior such as diversion, medical error, hazardous behavior, and protocol noncompliance.
