Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple display panels are used to cover various functions in smart cockpit, then the display coverage and functional completeness are improved, but the energy consumption increases and the actual utilization rate decreases

Engineering Contradiction:
Improvedisplay coverageVSAvoidenergy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

A single display panel is designed to serve multiple functions by switching its optical path to different display surfaces. The display panel can present images to the driver, front passenger, and rear passengers sequentially or simultaneously through the optical path selection module, replacing the need for multiple separate display panels and reducing overall energy consumption.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The optical path selection module dynamically switches the transmission path of light from the display panel to different destinations based on real-time requirements. This dynamic switching allows the same display panel to adaptively serve different display surfaces (windshield, front window, rear window) according to the driver's needs, maintaining high versatility while reducing energy consumption.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple display panels are installed in the cockpit, then the display functionality is enhanced, but the device complexity and cost increase

Engineering Contradiction:
Improvedisplay functionalityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple display functions that would traditionally require separate display panels are merged into a single display panel system. The optical path selection module enables one display panel to project images to multiple different surfaces (windshield, front window, rear window), consolidating hardware resources and reducing system complexity while maintaining comprehensive display functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single display panel is designed with universal capability to serve multiple display surfaces through optical path switching. This multi-functional design eliminates the need for separate dedicated display panels for different locations, thereby reducing the overall number of components and simplifying the display system architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Use of energy by moving object

If a single display panel switches between multiple optical paths, then the energy consumption is reduced, but the optical path selection complexity increases

Engineering Contradiction:
Improveenergy consumptionVSAvoidoptical path selection complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

An optical path selection module acts as an intermediary between the single display panel and multiple display surfaces. This intermediary component manages the complexity of optical path switching by providing a dedicated mechanism (such as movable mirrors or prisms) that routes light to different destinations, thereby isolating the complexity from the display panel itself and enabling energy-efficient single-panel operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A display apparatus is adapted to display on at least one of a first display surface and a second display surface, and includes a display panel, an optical path selection module, and at least one reflective element. The display panel is provided with the first display surface, and is adapted to emit an image beam. The optical path selection module is disposed on a transmission path of the image beam. The image beam transmitted along a first optical path after passing through the optical path selection module is adapted to display a first image on the first display surface. The image beam transmitted along a second optical path after passing through the optical path selection module is adapted to display a second image on the second display surface. The first image is different from the second image. The at least one reflective element is disposed on the second optical path.
