Display case door with door handle camera
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Customizing advertisements on refrigerated display case doors for different customers is challenging due to limitations in existing display technologies.
Innovation Solution
A display case door with a transparent panel and a door handle integrated with a camera positioned to face away from the panel, allowing for facial recognition and personalized advertising, along with an aperture for power cable management, enabling easy installation and maintenance without retrofitting the door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cameras and display technologies are integrated into refrigerated display case doors for customized advertising, then customer personalization capability is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The camera is nested within the door handle structure, with the handle base serving as the camera housing. The power cable aperture is integrated into the handle structure, allowing cables to pass through the handle base. This nesting approach embeds multiple functions (camera mounting, cable management, structural support) within a single component, reducing overall system complexity while enabling customized advertising capabilities through facial recognition technology.
2Adaptability or versatility
If cameras are mounted on door handles for facial recognition, then customer recognition capability is improved, but ease of maintenance deteriorates
Solution Approach 1:
The camera is extracted as a separable component from the door handle structure. The handle base serves as the camera housing, but the camera can be removed independently through the integrated aperture. The power cable aperture allows for easy disconnection and reconnection of cables, enabling maintenance personnel to access and replace the camera without dismantling the entire door handle assembly, thus improving ease of maintenance while maintaining facial recognition capability.
3Ease of manufacture
If power cables are routed through the door handle for camera power supply, then ease of installation is improved, but aesthetic appearance may deteriorate
Solution Approach 1:
The power cable aperture is positioned at a specific location on the door handle base, creating a localized functional opening that does not compromise the overall aesthetic design. The aperture is strategically placed to allow cable passage while maintaining the visual integrity of the handle's exterior surfaces. This localized approach enables simple cable routing for easy installation while minimizing impact on the door handle's aesthetic appearance.

AI summary
In one general aspect, the subject matter described in this specification can be embodied in a display case door that includes a transparent panel and a door handle coupled to the transparent panel. The handle includes a camera that is coupled to the handle. The camera is positioned such that a field of view of the camera is aimed away from the transparent panel. The handle includes an aperture opposite the camera lens. The aperture receives a power cable extending away from the camera to a power source.
