Solution Overview
Problem
Existing vehicle walls and windows are underutilized for interactive or adaptive information display beyond their basic enclosure function.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If walls and windows are used only for their basic enclosure function, then their inherent structural integrity is maintained, but their utility for information display is limited
Solution Approach 1:
The patent applies multi-functionality by enabling vehicle walls and windows to serve dual purposes: maintaining their basic enclosure function while simultaneously providing adaptive information display capabilities through integrated holographic films and projection systems
Solution Approach 2:
The patent merges the structural enclosure elements (walls and windows) with information display technology by applying holographic films to these surfaces and integrating projection systems, thereby combining two previously separate functions into a unified system
2Adaptability or versatility
If holographic display technology is added to vehicle surfaces, then information display capability is enhanced, but the complexity of the system increases
Solution Approach 1:
The patent applies segmentation by dividing the information display system into independent functional modules: holographic films applied to specific wall/window surfaces, separate projection units positioned at strategic locations, and distributed sensor systems, allowing each component to be optimized and maintained independently
Solution Approach 2:
The patent uses an intermediary approach by introducing a control system that acts as a mediator between sensor inputs and the projection/holographic display components, coordinating their operations to achieve adaptive and interactive display functionality without requiring direct complex interconnections between all components
3Ease of operation
If display information is shown on window surfaces, then information accessibility is improved, but the view through the window may be obstructed
Solution Approach 1:
The patent applies local quality by displaying information at specific localized areas on the window surface rather than covering the entire window, and by using holographic projection technology that can be selectively activated only when and where information needs to be displayed, preserving the window's transparency and view quality in other areas and times
