Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio environment is customized for a specific user, then audio experience quality is improved, but the customization must be repeated for each new user entering the environment, increasing time consumption and operational complexity
Solution Approach 1:
The patent creates a portable audio profile that copies user preferences, hearing adjustments, and audio settings from one device to another. This profile acts as a replicable template that can be instantly applied across different audio environments, eliminating the need to recreate customization for each new user or device combination.
Solution Approach 2:
The system performs preliminary audio customization and hearing adjustments in advance, storing them in a portable profile. When a user enters a new audio environment, the pre-prepared profile is automatically applied, eliminating the need for real-time customization setup and ensuring immediate optimal audio experience.
2Ease of operation
If audio environment is customized for a specific user, then personal audio preferences are satisfied, but the customization is tied to a specific audio environment, reducing adaptability to different environments
Solution Approach 1:
The patent creates a universal audio profile that can be applied across multiple audio environments and devices. The profile contains user preferences and hearing adjustments that are not tied to any specific audio environment, enabling the same personalized audio experience to be reproduced in cars, homes, offices, and other diverse settings.
Solution Approach 2:
The system transitions audio customization from a location-specific dimension to a user-specific dimension by creating portable profiles associated with individual users rather than specific environments. This allows the customization to follow the user across different spatial contexts, adding the dimension of user portability to the audio experience.
3Ease of operation
If hearing deficiency compensation is applied, then audio accessibility is improved, but repeated hearing tests are required for each customization session, increasing complexity and time consumption
Solution Approach 1:
The system performs hearing tests and determines hearing deficiency compensation parameters in advance, storing the results in a portable audio profile. This preliminary action eliminates the need to conduct hearing tests repeatedly during each customization session, as the hearing profile is already established and can be instantly applied to new audio environments.
Solution Approach 2:
The system enables hearing deficiency compensation to be automatically applied based on stored profile information without requiring the user to undergo repeated hearing tests. The portable profile contains pre-determined compensation parameters that the system automatically implements, reducing the burden on the user and eliminating complex repeated testing procedures.
