Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for providing tourist information face challenges such as limited geographic range, language barriers, interference from other wireless devices, and the inability to seamlessly integrate pre-recorded commentary with live tours, making it difficult for tourists to access relevant information and for tour guides to effectively communicate with large groups in multiple languages.
Innovation Solution
A radio digital system using DECT technology with an optical user interface for coupling audio communication devices, allowing for simultaneous communication in multiple languages and enabling tourists to select their preferred language, with devices that include an optical reader, microcontroller, and storage module for storing commentary, and a map with embedded optic codes for channel and language selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless devices are used for providing tour commentary, then tourists can access information remotely, but the geographic range is limited and network connectivity is required
Solution Approach 1:
The system divides the tour guide service into two independent components: a portable base station that provides wireless communication within range, and a network-connected system that provides unlimited geographic access. This segmentation allows the portable base station to operate independently without requiring continuous network connectivity, resolving the contradiction between ease of operation and geographic versatility.
2Ease of operation
If pre-recorded audio tracks are used for individual tours, then tourists can receive commentary independently, but interaction features are limited
Solution Approach 1:
The system transitions from static pre-recorded audio tracks to dynamic real-time communication. The portable base station enables tourists to interact with the tour guide through two-way voice communication, allowing the system to adapt to tourist questions and comments in real-time, thus resolving the contradiction between independent tour capability and interaction versatility.
3Productivity
If multiple tour groups use wireless devices simultaneously, then more tourists can be served, but interference from other wireless devices increases
Solution Approach 1:
The portable base station acts as an intermediary that manages communication for multiple tour groups. It uses DECT technology with automatic channel selection to mediate between multiple groups, preventing interference by assigning different communication channels to different groups, thus resolving the contradiction between productivity and interference levels.
4Adaptability or versatility
If tour guides speak in multiple languages, then more tourists can be accommodated, but communication complexity increases
Solution Approach 1:
The system implements self-service language selection where tourists choose their preferred language through the user interface of their portable base station. This eliminates the need for the tour guide to manually switch between languages, reducing communication system complexity while maintaining multi-language versatility.
5Reliability
If DECT technology is used for audio communication, then clear interference-free communication is achieved, but device coupling complexity increases
Solution Approach 1:
The portable base station and tourist devices perform automatic self-coupling using DECT technology. The devices automatically establish connections without requiring manual pairing or complex configuration by users, thus maintaining communication clarity while reducing the perceived complexity for end users.
Solution Approach 2:
The system replaces manual mechanical coupling processes with automatic electronic coupling through DECT technology. The optical reader provides visual guidance for channel selection, substituting complex manual configuration with simplified visual interaction, thereby maintaining reliability while reducing operational complexity.

Function Achieved in This Case
Enables clear, interference-free communication with up to 7600 tour groups simultaneously, allowing tourists to access commentary in their chosen language without the need for continuous network connectivity, and allows tour guides to provide live and pre-recorded commentary, enhancing the tourist experience by simplifying navigation and interaction with points of interest.
Implementation Method 1
an optical reader programmed with a library of codes and corresponding commands, wherein the optical reader scans and decodes an optical code
Data Source
AI summary
Devices and methods for providing commentary for multiple points of interests utilize audio communication devices having an optic code reader, a microcontroller, a transmitter/receiver, a storage module and a speaker and/or headphone jack. Two or more audio communication devices may be synced to the same channel. A primary audio communication device sends a signal that triggers a dependent audio communication device to play a prerecorded commentary regarding a selected point of interest in a language selected by a person using the dependent audio communication device. A map having icons representing points of interest includes optic codes embedded within the icons. When an audio communication device scans an icon with an optic reader, a triggering signal causes the audio communication device and any dependent audio communication devices to play a corresponding commentary and a language selected by a user.
