Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indoor information push systems for exhibition centers and supermarkets are inconvenient, costly, and lack indoor positioning and navigation capabilities, requiring expensive guiding devices and manual updates, and often result in users getting lost in large spaces.
Innovation Solution
An indoor navigation and information push system using LED lighting devices with built-in Wi-Fi modules, forming an indoor wireless network with an information storage and navigation server, allowing users to connect and receive location-based information and navigation services without the need for dedicated guiding devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dedicated guiding devices with information push modules are deployed for each exhibit/product, then information push capability is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent applies universality by enabling ordinary LED lighting devices to perform multiple functions: traditional illumination plus wireless communication (Wi-Fi module) plus information push functionality. Instead of deploying dedicated guiding devices for each exhibit, the system uses existing LED fixtures throughout the space to serve as both lighting and information delivery points, thereby reducing device complexity while maintaining information push capability
Solution Approach 2:
The patent merges the functions of lighting devices and information push modules into a single integrated system. LED lighting devices are equipped with Wi-Fi modules to combine illumination and wireless communication capabilities, and the information storage server consolidates data for all exhibits, merging what would otherwise be separate distributed systems into a unified architecture
2Ease of operation
If dedicated guiding devices are used for each exhibit/product, then information delivery is improved, but cost increases
Solution Approach 1:
The patent eliminates the need for expensive dedicated guiding devices by making ordinary LED lighting devices multi-functional. The same LED fixtures that provide illumination are also equipped with Wi-Fi modules to deliver information, thereby achieving information delivery capability without the need for separate expensive hardware for each exhibit
Solution Approach 2:
The patent uses wireless communication to copy and transmit exhibit information from a centralized storage server to user terminals. Instead of requiring physical hardware at each exhibit location, the system creates digital copies of information that can be wirelessly transmitted on demand, significantly reducing hardware requirements and cost
3Loss of information
If guiding devices store all exhibits/merchandise information, then information availability is improved, but storage space requirements and hardware upgrade costs increase
Solution Approach 1:
The patent introduces an information storage server as an intermediary between the exhibit database and user terminals. This centralized server acts as a mediator that stores all exhibit information and provides it on demand to users via wireless communication, eliminating the need for each guiding device to store complete information locally and thereby reducing storage space requirements at individual device locations
4Device complexity
If manual search and location methods are used in existing systems, then device simplicity is maintained, but user time and convenience deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where user terminals automatically receive information pushes based on their location and preferences. The system continuously monitors user position relative to exhibits and provides relevant information without requiring manual searching, creating a closed-loop system that adapts to user needs and significantly reduces search time while maintaining reasonable system complexity
