Vehicle Roof Panel Projector Mounting on Support Beam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for projecting images on vehicle roof panels are cumbersome and time-consuming due to large tolerances in mounting the projector device and roof panel assembly, leading to increased manufacturing and installation costs.
Innovation Solution
A roof panel assembly with a projector device mounted directly on the support beam between interior surfaces, allowing for smaller manufacturing tolerances and optical or digital adjustments, enabling easy installation and calibration by users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the projector device is arranged separately in the interior space or on a roof body frame part, then the projector device can be mounted independently, but the mounting tolerances add up and require time-consuming calibration and adjustment procedures
Solution Approach 1:
The patent merges the projector device with the roof panel assembly by arranging the projector device on the support beam of the roof panel assembly. This integration ensures that the relative positioning between the projector device and the projection surface (roof panel) is fixed and precise, eliminating the accumulation of mounting tolerances that would occur with separate mounting. The projector device and roof panel are manufactured and assembled as a coordinated unit, guaranteeing accurate image projection without requiring extensive calibration.
2Ease of manufacture
If the projector device is arranged separately in the interior space or on a roof body frame part, then the projector device can be mounted independently, but the calibration and adjustment procedures significantly add to the costs
Solution Approach 1:
The patent merges the projector device with the roof panel assembly by arranging the projector device on the support beam of the roof panel assembly. This integration ensures that the relative positioning between the projector device and the projection surface (roof panel) is fixed and precise, eliminating the accumulation of mounting tolerances that would occur with separate mounting. The projector device and roof panel are manufactured and assembled as a coordinated unit, guaranteeing accurate image projection without requiring extensive calibration.
3Manufacturing precision
If the projector device is mounted on the support beam of the roof panel assembly, then the relative positioning is precise and tolerances are minimized, but the projector device becomes integrated into the roof panel assembly
