Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ride-sharing systems face challenges in ensuring accurate vehicle and passenger verification, particularly for color-blind individuals and in varying lighting conditions, and rely on GPS for location-based content delivery which raises privacy concerns, while rooftop carriers impact fuel economy and vehicle dynamics.
Innovation Solution
A system using DLP headlights equipped with sensors and a web-based application for environment-responsive image projection, adjusting images based on environmental conditions and user interactions, enabling efficient ride service verification and enhancing safety and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If color-matching technology with beacon is used to improve pickup identification, then pickup accuracy is improved, but reliability deteriorates for color-blind individuals and in bright daylight conditions
Solution Approach 1:
The system uses color-changing LED lights on the vehicle exterior that can display different colors (e.g., green, yellow, red) to indicate vehicle status and identity. This provides a more reliable visual identifier than static color-matching beacons, as color changes are more detectable and meaningful across different lighting conditions and for color-blind individuals.
Solution Approach 2:
The system introduces an intermediary verification mechanism where the ride-sharing application on the passenger's mobile device communicates with the vehicle's system to confirm vehicle identity and status. This intermediary layer ensures accurate identification regardless of environmental conditions or passenger visual limitations.
2Productivity
If GPS-enabled triggers are used for location-based content delivery, then advertising effectiveness is improved, but privacy concerns increase
Solution Approach 1:
The system activates advertising content delivery only in specific local contexts - when the vehicle is stationary or moving at low speeds in designated advertising zones. This localized approach delivers ads effectively while minimizing continuous GPS tracking and privacy intrusion, as advertising is not pursued in all locations and at all times.
3Illumination intensity
If rooftop carriers are installed for on-car advertising, then advertising visibility is improved, but fuel economy deteriorates
Solution Approach 1:
The system replaces physical rooftop advertising carriers with digital advertising displays integrated into the vehicle's existing electronic systems, such as the headlight projectors and exterior LED lights. This substitution eliminates the need for mechanical rooftop structures, maintaining advertising visibility through digital content while avoiding the fuel economy penalties associated with physical carriers.
Solution Approach 2:
The vehicle's existing lighting systems (headlights, taillights, turn signals) are made multi-functional by enabling them to display advertising content in addition to their primary safety functions. This universal use of existing components provides advertising visibility without requiring separate dedicated advertising hardware that would impact fuel economy.
4Illumination intensity
If DLP headlights are used for high-resolution image projection, then visibility and field of view are improved, but device complexity increases
Solution Approach 1:
The DLP headlight system is designed to perform multiple functions: traditional illumination, glare-free high beams, hazard warning symbol projection, and advertising content display. By making the headlight system universal and multi-functional, the patent justifies the increased device complexity through the consolidation of multiple systems into one, rather than adding separate systems for each function.
