Separated UWB Antenna Layout for Easier Smart Lock Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart door locks face installation challenges due to the need for accurate and stable connection of radio frequency terminals, which complicates the installation process and affects signal stability.
Innovation Solution
A UWB antenna is integrated into the rear lock body, eliminating the need for traditional radio frequency terminal connections by using a cable to connect directly to components in the front lock body, ensuring easy installation and stable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional radio frequency terminal connection method is used, then signal communication can be established, but installation complexity increases and installation difficulty arises due to the need for accurate docking of male and female connectors in small space
Solution Approach 1:
The patent separates the antenna from the radio frequency terminal connection system. The UWB antenna is integrated into the rear lock body as an independent component, eliminating the need for separate connector docking. This segmentation removes the complex terminal connection process while maintaining signal communication functionality through direct cable connection.
Solution Approach 2:
The patent extracts the antenna function from the traditional terminal connection system and integrates it directly into the rear lock body. By taking out the need for male-female connector docking and replacing it with an integrated antenna design, the installation process is simplified while signal stability is preserved through direct cable connection to the front lock body components.
2Adaptability or versatility
If radio frequency terminal connection is implemented, then wireless communication function is achieved, but device complexity increases due to the need for connectors and precise alignment mechanisms
Solution Approach 1:
The patent merges the antenna function with the rear lock body structure. The UWB antenna is integrated directly into the rear lock body, combining what were previously separate components (antenna and connector system) into a unified structure. This merging reduces device complexity by eliminating the need for separate connectors and alignment mechanisms while maintaining wireless communication capability.
Solution Approach 2:
The rear lock body serves multiple functions: it provides structural support, houses the UWB antenna, and facilitates cable routing through the oblique groove. This multi-functionality reduces the need for additional specialized components, thereby simplifying the overall device structure while maintaining wireless communication functionality.
3Loss of time
If cable routing is simplified through oblique groove design, then installation time is reduced, but space utilization in rear lock body becomes more challenging
Solution Approach 1:
The patent introduces an oblique groove that provides a three-dimensional cable routing path through the rear lock body. This dimensional approach allows the cable to pass through the structure efficiently without requiring additional flat mounting surfaces or complex external routing, thus saving installation time while effectively utilizing the available volume of the rear lock body.
