Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If BLE devices are used for data acquisition and management, then device portability and low cost are improved, but management efficiency deteriorates due to the need for large quantities of human and material resources
Solution Approach 1:
The patent introduces a gateway device as an intermediary between BLE devices and the cloud server. The gateway collects data from multiple BLE devices locally and transmits aggregated data to the cloud, eliminating the need for direct cloud connection for each BLE device. This intermediary approach maintains the low cost and portability of BLE devices while significantly improving management efficiency through centralized data collection and processing.
2Device complexity
If BLE devices operate at close range only, then device simplicity is improved, but coverage range deteriorates, limiting data acquisition to close proximity only
Solution Approach 1:
The patent extends the coverage range by introducing a multi-dimensional communication architecture. BLE devices maintain their simple close-range communication capability, while the gateway provides wireless coverage extension and the cloud server adds remote access capability through internet connectivity. This dimensional extension allows BLE devices to remain simple while achieving wide-area data acquisition through the layered architecture.
3Length of stationary object
If multiple gateway devices are deployed to cover wide range, then coverage area is improved, but device density increases, raising user costs
Solution Approach 1:
The patent designs the gateway device with multi-functionality to reduce the number of devices needed. The gateway simultaneously performs BLE data collection, WiFi cloud communication, and optional RGB lighting functions. By consolidating multiple functions into a single device, the system achieves wide coverage area without increasing gateway device density, thereby reducing overall system cost.

AI summary
This invention refers to a gateway of Internet of Things which supports Bluetooth, WiFi protocol and adjustment of smart light. From top to bottom, it consists of the movably connected top cover, surface cover, and bottom shell. The top cover fastens the shading film, light guide plate and light panel to surface cover's step surface from the top down successively; the surface cover is equipped with a Bluetooth antenna and a WiFi antenna on its inner wall; there is an electric connection between main board within the bottom shell and light panel, Bluetooth antenna and WiFi antenna. Besides locating multiple devices which support BLE protocol within about 350-meter-radius range and acquiring their data, this structure uploads the data to cloud server and exercises real-time control over these devices. Meanwhile, users may log into cloud server by mobile phone to control RGB SMD lamp—adjust light color and display model in real time. Thus, it can be seen that this structure can offer various lighting combinations that can improve user experience.
