Windshield Lyrics Projector for Automobile Dashboard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lyrics display apparatuses for automobiles do not provide a convenient and safe way for passengers to view song lyrics while driving, as they require drivers to look at their cellular phones for lyrics, which is unsafe.
Innovation Solution
A lyrics display apparatus with a hollow cylindrical lower and upper base unit, featuring a rechargeable battery, central processing unit, projector, microphone, and display screen, allowing the central processing unit to recognize and project song lyrics onto the windshield, enabling passengers to sing along safely without the driver needing to access a cellular phone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drivers use cellular phones to look up lyrics while driving, then passengers can sing along, but driver safety deteriorates due to distraction
Solution Approach 1:
The patent introduces a projector as an intermediary device that displays lyrics on the windshield, allowing passengers to view lyrics without the driver needing to interact with a cellular phone. The projector acts as a mediator between the lyrics source and the driver, presenting information in a way that does not require driver distraction.
Solution Approach 2:
The patent replaces the mechanical interaction of physically looking at and manually operating a cellular phone with an optical projection system. Instead of the driver visually engaging with a phone screen, the lyrics are projected onto the windshield, substituting a mechanical visual inspection process with an optical projection process that does not require driver attention.
2Reliability
If a projector is added to display lyrics on the windshield, then driver safety improves, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into the lyrics display apparatus, including a rechargeable battery for power storage, a microphone for capturing audio, a speaker for audio output, and a display screen for alternative lyric display. This multi-functionality allows the single device to handle various tasks, reducing the need for separate components and thereby managing complexity while enhancing capabilities.
Solution Approach 2:
The patent employs a nested structure where the lower base unit and upper base unit are stacked vertically, with the upper base unit containing the projector, battery, and other components. This nested arrangement allows compact integration of multiple functions into a space-efficient configuration, reducing overall device complexity while maintaining all necessary features.
3Ease of operation
If rechargeable battery and storage elements are integrated into the apparatus, then portability improves, but manufacturing complexity increases
Solution Approach 1:
The patent divides the apparatus into two separate base units: a lower base unit containing the projector and an upper base unit containing the rechargeable battery and storage elements. This segmentation allows each unit to be manufactured and tested independently before final assembly, simplifying the manufacturing process while enabling portable operation. The modular design facilitates easier assembly compared to integrating all components in a single unit.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe and convenient display of song lyrics on the windshield, allowing passengers to sing along without distracting the driver, while also allowing wireless communication and use of the automobile's audio jack or battery as a power source.
Implementation Method 1
the projector is configured to display lyrics of the song recognized and acquired by the central processing unit onto a windshield of the automobile
Implementation Method 2
A rechargeable battery, a first storage element, and a central processing unit are disposed within the hollow cylindrical upper base unit
Implementation Method 3
The central processing unit is configured to recognize and acquire lyrics of a song from the first storage element when the microphone relays the song to the central processing unit
Implementation Method 4
A speaker and a microphone are also disposed on the upper side of the hollow cylindrical upper base
