Solution Overview
Problem
Portable voice assistant devices face challenges in providing effective visual and audio feedback in loud or noisy environments, such as automobiles, due to noise, sunlight, and unpredictable ambient conditions, making it difficult for users to interact with these devices.
Innovation Solution
The implementation of portable voice assistant devices equipped with linear lighting elements, such as light bars, and audio settings that maintain visibility and audibility, along with tactile buttons for easy identification, allows for visual and audio indicators to be conveyed to users in various environments, including those with high noise and sunlight exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional visual and audio feedback methods are used in portable voice assistant devices, then the devices can provide basic user interaction capabilities, but the visibility of visual indicators and audibility of audio signals deteriorate in loud or noisy environments with sunlight exposure
Solution Approach 1:
The patent employs light emitting elements that emit light in specific colors or color patterns to provide visual feedback. The use of colored LEDs or similar elements allows the visual indicators to stand out against varying ambient light conditions, including direct sunlight, thereby maintaining visibility and reliability of user interaction across different environmental conditions.
2Reliability
If traditional visual and audio feedback methods are used in portable voice assistant devices, then the devices can provide basic user interaction capabilities, but the audibility of audio signals deteriorates in loud or noisy environments
Solution Approach 1:
The patent introduces tactile buttons as an intermediary input mechanism that does not rely on audio signals. These tactile elements provide a physical interface for user interaction that is independent of noise levels, allowing users to input commands or provide feedback through touch rather than voice, thereby overcoming the limitation of audio signal audibility in noisy environments.
3Illumination intensity
If linear lighting elements are added to portable voice assistant devices to improve visibility, then the visual indicator visibility is enhanced in various environments, but the device complexity increases
Solution Approach 1:
The patent divides the lighting system into discrete light emitting elements arranged in a linear configuration. This segmentation allows the visual feedback system to be implemented using individual LEDs or similar elements that can be controlled independently, providing flexible visual indicators while keeping each element simple and manageable, thus limiting the overall complexity increase.
Solution Approach 2:
The linear lighting elements serve multiple functions: they provide visual feedback for user interaction, indicate device status, and can potentially serve as aesthetic design elements. By making the lighting system multi-functional, the patent justifies the added complexity through the versatility of the implementation, where a single added component type serves several purposes simultaneously.
4Ease of operation
If tactile buttons are added to portable voice assistant devices to improve ease of operation in noisy environments, then the ease of operation is enhanced, but the device complexity increases
Solution Approach 1:
The patent incorporates tactile buttons with specific local characteristics - raised surfaces or distinct textural properties - that allow users to identify and operate them through touch alone without visual assistance. This local quality enhancement at specific interaction points provides noise-resistant operation while keeping the overall device structure relatively simple, as only specific localized areas are modified rather than the entire device.
