Rear-Door Mounted Vehicle Projector for Obstruction-Free Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles require aftermarket installations or separate display systems for media projection, often necessitating rearrangement of the vehicle cabin to minimize obstruction, leading to incompatibility and cumbersome setup.
Innovation Solution
A portable projector arrangement that selectively couples with a vehicle's rear door, utilizing an attachment mechanism with clips and elongate members to mount a video projector and screen, powered by a solar cell, allowing projection onto a screen when the door is open, with wireless communication for control and audio output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a projection device is implemented in a vehicle, then media projection capability is improved, but vehicle cabin structures must be rearranged to limit obstruction
Solution Approach 1:
The projection system is segmented into a portable external unit that attaches to the vehicle exterior (rear door) rather than integrating it into the cabin. This separates the projection function from the vehicle structure, eliminating the need for cabin rearrangement while maintaining projection capability.
Solution Approach 2:
A portable container serves as an intermediary between the vehicle and the projection system. The container houses the projector and attaches to the rear door, mediating the connection without requiring modifications to the vehicle cabin structure.
2Adaptability or versatility
If aftermarket display assemblies are installed, then entertainment functionality is improved, but installation compatibility and ease are worsened
Solution Approach 1:
The attachment mechanism is designed with universal compatibility features, using common vehicle components (handles, elongate members) that can be found on various vehicle types. This allows the same projection system to be installed on different vehicles without custom manufacturing for each model.
Solution Approach 2:
The system uses removable and reconfigurable attachment components (clips, elongate members, brackets) that can be dynamically assembled and disassembled. This dynamic assembly approach simplifies installation and removal while maintaining compatibility across different vehicle platforms.
3Ease of operation
If a portable projector arrangement is used, then installation complexity is reduced, but power supply capability is worsened
Solution Approach 1:
The system incorporates a solar cell on the portable container that generates electrical power autonomously from sunlight. This self-service power generation eliminates the need for external power sources or complex wiring to the vehicle, providing energy independence for the projection system.

AI summary
A projector arrangement for a vehicle includes an attachment mechanism that selectively couples with a rear door of the vehicle. The projector arrangement further includes a video projector coupled with the attachment mechanism. The video projector is configured to project image data in a direction toward the vehicle when the rear door is in an open position. A portable container selectively houses the attachment mechanism and the video projector.
