UV Germicidal Lamp Fixture for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, especially when used by multiple individuals, pose a risk of germ and virus transmission due to the lack of effective sterilization methods, as existing lamp positioning systems are complex and not designed for sterilization purposes.
Innovation Solution
A display device equipped with an ultraviolet (UV) germicidal lamp, a simplified fixture member with adjustable clamps, and a control circuit that includes a sensor for detecting human proximity and a signal receiver for wireless control, allowing for reliable attachment and safe operation of the UV lamp.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional positioning member with gears and lever is used to fix the light member, then the light member can be reliably fixed to the display device, but the structure becomes complicated
Solution Approach 1:
The positioning member is divided into separate functional components: a base, a clamp piece with clamp portions, and an elastic element. This segmentation simplifies the overall structure by eliminating complex gears and levers while maintaining reliable fixing through the elastic clamp mechanism
Solution Approach 2:
The elastic element automatically provides clamping force to secure the light member to the display device rim. The clamp piece self-adjusts to fit the rim through the elastic force, eliminating the need for complex adjustment mechanisms while ensuring reliable fixation
2Adaptability or versatility
If the light member is designed for illumination only, then the structure is simple, but it cannot provide sterilization function needed during pandemics
Solution Approach 1:
The light member is designed to perform multiple functions: it can emit visible light for illumination and UV light for sterilization. The positioning member is also designed to accommodate different types of light members (traditional bulbs, LED, OLED, or UV germicidal lamps), making the system versatile for both illumination and sterilization applications
Solution Approach 2:
The system allows dynamic configuration where the light member can be replaced or adjusted based on needs. The positioning member with its elastic clamp design enables easy installation and removal of different light member types, allowing the system to adapt between illumination-only mode and sterilization-capable mode

AI summary
The display device with an ultraviolet (UV) germicidal lamp includes a display device, an UV germicidal lamp, a power electrically connected to the UV germicidal lamp, a control circuit electrically connected to the UV germicidal lamp, and a fixture member detachably fixing the UV germicidal lamp to a circumferential rim of the display device. The fixture member includes a base, a first clamp piece, and a second clamp piece. The base is joined to the UV germicidal lamp. The first and second clamp pieces are mounted at interval on the base, forming a clamp interval in between. An elastic element is provided between the second clamp piece and the base for forcing the second clamp piece towards the first clamp piece. Therefore, by adjusting the clamp interval, the UV germicidal lamp may be reliably clamped to the display device.
