Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation methods are inadequate for quickly and intuitively guiding users within large, modernized spaces like shopping centers, as they rely heavily on maps and manual infrared sensors, which are inefficient and require extensive physical apparatuses and labor.
Innovation Solution
A navigation method and device that receives start and end point information, acquires a target path navigation video based on environmental images or text information, and sends this video to a user's device for intuitive navigation, eliminating the need for manual infrared sensors and reducing the complexity of navigation systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual infrared sensors are installed for indoor navigation, then navigation positioning can be achieved, but the system complexity and installation cost increase significantly
Solution Approach 1:
The patent uses image copying technology to capture and process visual scenes, creating digital representations of the physical environment. These image copies are then used for navigation without requiring physical sensors to be installed in the environment, thus achieving positioning while reducing system complexity
Solution Approach 2:
The patent replaces the mechanical infrared sensor system with a visual-based navigation system using image processing and computer vision algorithms. This substitution eliminates the need for specialized hardware sensors while maintaining navigation functionality
2Ease of operation
If traditional map-based navigation is used, then navigation functionality is provided, but the intuitiveness and user experience are insufficient
Solution Approach 1:
The patent enhances navigation intuitiveness by overlaying colorful directional indicators, arrows, and visual cues on the captured images. These visual elements provide clear directional guidance while maintaining the real environmental context, making navigation more intuitive than traditional map-based systems
Solution Approach 2:
The patent transitions from 2D map-based navigation to 3D immersive visual navigation by displaying navigation instructions directly on captured images of the real environment. This adds the dimension of spatial realism, allowing users to see navigation cues in the context of their actual surroundings
3Measurement precision
If pre-installed infrared sensors are used for indoor navigation, then positioning accuracy is achieved, but the deployment time and labor requirements increase
Solution Approach 1:
The patent enables the navigation system to automatically capture images and extract positioning information without requiring manual sensor installation. The system uses existing mobile device cameras and automatically processes images to determine location, eliminating deployment time and labor requirements while maintaining positioning accuracy
4Adaptability or versatility
If manual infrared sensor installation is performed, then navigation coverage is established, but the labor force and installation cost increase
Solution Approach 1:
The patent makes the mobile device itself universal by using its existing camera and processing capabilities for navigation. Any smartphone or mobile device can perform navigation functions without requiring specialized sensor installation, thus achieving wide coverage while eliminating installation effort
Solution Approach 2:
The system creates digital copies of environments through image capture, allowing navigation in any captured space without physical sensor deployment. This copying approach enables flexible navigation coverage adaptation without additional installation effort
