Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sounds are reproduced based on user position information, then the information providing versatility is improved, but the sound management complexity increases
Solution Approach 1:
The patent segments the reproduction task by associating specific sounds with specific ranges (areas on the map). Each sound is tied to a defined geographic range, allowing the system to manage multiple sounds independently based on their spatial locations. This segmentation enables the system to reproduce multiple sounds simultaneously without overwhelming complexity, as each sound's reproduction is governed by its associated range rather than requiring complex centralized control.
Solution Approach 2:
The patent introduces range information as an intermediary between the user position and sound reproduction decisions. Instead of directly managing which sounds to reproduce based on complex position analysis, the system uses range information as a mediator that simplifies the decision-making process. The range information acts as an intermediate layer that translates user position into actionable sound reproduction instructions, reducing the overall system complexity.
2Measurement precision
If sound volume is increased to ensure high-priority sounds are heard, then the sound clarity is improved, but the auditory comfort decreases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting sound volume based on the user's position relative to the sound source. Instead of using a fixed high volume for all sounds, the system modifies the volume parameter continuously as the user moves. This ensures that high-priority sounds remain clear when the user is nearby while automatically reducing volume to maintain comfort when the user is farther away, thus resolving the contradiction between clarity and comfort.
3Loss of information
If sound reproduction continues in overlapping ranges, then the information completeness is improved, but the sound confusion increases
Solution Approach 1:
The patent implements dynamics by making the sound reproduction system adaptive to user movement. When the user enters an overlapping range where multiple sounds could be reproduced, the system dynamically adjusts its behavior based on the user's current position and movement history. This dynamic approach allows the system to maintain information completeness by continuing to provide relevant sounds while preventing confusion through intelligent selection and transition management.
Solution Approach 2:
The patent employs feedback mechanisms where the system monitors user position and movement history to determine which sounds to reproduce in overlapping ranges. The feedback from user position data allows the system to intelligently select between multiple available sounds, ensuring that the most relevant information is provided while avoiding confusion. The system continuously adjusts its output based on real-time position feedback.
Data Source
AI summary
An information providing system includes: a processor; and a memory storing instructions that, when executed by the processor, cause the information providing system to perform operations including: acquiring position information indicating a user position; acquiring at least one of pieces of data information, each including sound information representing a sound, range information associated with the sound information and representing a predetermined range on a map, and reproduction information associated with the sound information and indicating settings related to reproduction of the sound in the sound information; and reproducing a sound by referring to the at least one of pieces of data information based on the position information. In a case in which there are one or more pieces of range information representing ranges including the user position, the reproduction processing is executed for each of the one or more pieces of range information.
