Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio systems for mobile devices used in audio tours face maintenance and battery charging issues, and suffer from poor audio quality due to analog, noise-prone modulation methods, with limited memory and computing resources in receiving devices.
Innovation Solution
An audio system that integrates with building mobile communications infrastructure to transmit audio signals from a mobile device to loudspeakers or battery-operated terminals, using standardized mobile communications technology, allowing flexible audio tours with improved audio quality by maintaining a connection with the mobile communications base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If battery-powered receiving devices are used for audio tours, then portability and flexibility are improved, but maintenance effort and battery charging requirements increase
Solution Approach 1:
The patent extracts the battery-powered receiving devices from the system and replaces them with fixed loudspeakers integrated into the environment. This eliminates the need for portable battery-powered devices while maintaining audio tour functionality, thereby reducing maintenance effort and battery charging requirements.
Solution Approach 2:
The patent replaces expensive, maintenance-intensive battery-powered devices with simpler, fixed loudspeaker installations. The loudspeakers are integrated into the environment and do not require battery replacement or charging, effectively using a simpler, longer-lasting solution.
2Device complexity
If analog modulation methods are used for audio signal transmission, then device complexity is reduced, but audio quality deteriorates due to noise
Solution Approach 1:
The patent replaces analog modulation methods with digital communication protocols used in modern mobile devices. This substitution maintains system simplicity while dramatically improving audio quality by using digital signal transmission that is resistant to noise and interference.
3Ease of operation
If battery-powered terminals are used for receiving audio signals, then mobility is improved, but reliability deteriorates due to battery failure risk
Solution Approach 1:
The patent removes battery-powered terminals from the system and replaces them with fixed loudspeaker installations. This eliminates the battery component entirely, removing the source of reliability issues while maintaining the audio tour functionality through environmental integration.
4Device complexity
If limited memory and computing resources are used in receiving devices, then device complexity is reduced, but adaptability deteriorates for additional functions
Solution Approach 1:
The patent merges the audio processing functionality into centralized servers or cloud-based systems rather than embedding it in limited receiving devices. The fixed loudspeakers simply output audio signals while all computationally intensive functions are performed remotely, enabling unlimited adaptability without increasing device complexity at the receiving end.
