Snap-Fit Lamp Sensor Module for Optional User Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamps with human body sensors are not user-configurable, as the sensors are pre-mounted during manufacturing, limiting their adaptability to different usage needs.
Innovation Solution
A plug-in sensing device with snap-fit fasteners allows for easy mounting and detachment on lamps, featuring a base, cover, sensor, and connecting seat with adjustable snap-fit mechanisms, enabling users to choose sensor installation based on specific needs without modifying the lamp's original structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If human body sensors are pre-mounted during manufacturing by forming holes in lampshades or shortening luminous bodies, then the sensors can be securely integrated into the lamp structure, but users cannot optionally choose whether to mount the sensors according to actual needs and thus different usage needs cannot be met
Solution Approach 1:
The sensing device is divided into separate modular components: a base that attaches to the lamp body, a cover that houses the sensor, and the sensor itself. This segmentation allows users to install only the portions they need and easily detach or reconfigure them, providing optional sensor mounting without requiring permanent modifications to the lamp structure.
Solution Approach 2:
The base is designed with a movable connecting seat that can adjust its position along the lamp body. This dynamic adjustment capability allows the sensing device to adapt to different lamp sizes and shapes, enabling versatile installation options without requiring custom modifications for each lamp type.
2Ease of operation
If sensors are pre-mounted during manufacturing, then the mounting is secure and factory-completed, but it requires that securing and assembly have been completed at the factory so that users cannot optionally choose whether to mount the human body sensors according to actual needs
Solution Approach 1:
The base and cover are pre-assembled into a complete sensing device unit at the factory, with all necessary components (sensor, connecting mechanisms, limiting cavity) already in place. This preliminary assembly ensures manufacturing quality while allowing the complete unit to be easily attached or detached by users later, combining factory completion with user flexibility.
3Ease of operation
If the base and cover are designed as separate detachable components with snap-fit fasteners, then users can easily mount and detach the sensing device, but the connection mechanism must ensure structural reliability
Solution Approach 1:
The snap-fit fastening mechanism is extracted as a separate functional element between the base and cover. The first snap-fit fastener connects the base to the lamp body, while the second snap-fit fastener connects the connecting seat to the lamp body. This extraction allows for easy user assembly and detachment while maintaining reliable connections through dedicated fastening structures.

AI summary
The present application provides a plug-in sensing device and a lamp. The plug-in sensing device comprises: a base, the base being provided with a first snap-fit fastener, and the first snap-fit fastener being used for snap-fitting with a lower edge of a lamp body so as to connect the base and the lamp body together; a cover, the cover covering the base and defining a limiting cavity together with the base; a sensor, at least part of the sensor being disposed in the limiting cavity, and a sensing portion on the sensor being exposed outside the limiting cavity; and a connecting seat, the connecting seat being disposed between the base and the cover, the connecting seat being provided with a second snap-fit fastener, and the second snap-fit fastener being used for snap-fitting with an upper edge of the lamp body so as to connect the connecting seat and the lamp body together. According to the present application, a user can optionally choose whether to mount the sensor, and thus different usage needs can be met. Furthermore, since the first snap-fit fastener, the second snap-fit fastener and the lamp body are connected, the costs can be reduced without improving an original structure of the lamp body.
