Solution Overview

Problem

Existing vehicle display devices lack effective means to adjust display height and orientation based on the position of the driver or passenger, leading to suboptimal viewing and information presentation.

Innovation Solution

A display device with a drive module using a ball screw member and link member, along with a four-bar linkage structure, adjusts the display's position and orientation based on the occupant's facial features, incorporating a see-through module for additional information transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the display size is increased to provide more convenience information, then the information display capability is improved, but the viewing angle and alignment with the driver's position deteriorate

Engineering Contradiction:
Improveinformation display capabilityVSAvoidviewing alignment
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The display device is made dynamically adjustable in position and orientation through a drive module. The display can move vertically and tilt at various angles, allowing it to adapt to different driver positions and viewing requirements while maintaining optimal visibility of the increased display area.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the display position is made adjustable to improve viewing alignment, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveviewing alignmentVSAvoidadjustment mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The complex mechanical adjustment system is replaced with a drive module that uses motorized actuation. The drive module converts electrical signals into precise mechanical movements, simplifying the control interface while achieving the required positional and angular adjustments through automated actuation rather than manual mechanical manipulation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Loss of information

If a see-through module is added to provide additional information transmission, then the information delivery capability is improved, but the device complexity increases

Engineering Contradiction:
Improveinformation transmissionVSAvoidmodule integration
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The see-through module is merged with the main display structure, sharing common mounting mechanisms and control systems. The see-through panel is integrated into the display assembly such that it functions as part of the overall information presentation system, reducing the need for separate mounting hardware and control circuits.

Inventive Principle:
Principle #5Merging (Combining)

4Area of stationary object

If the display is positioned at the lowest point to maximize see-through area, then the see-through capability is improved, but the viewing angle for upper display areas deteriorates

Engineering Contradiction:
Improvesee-through areaVSAvoidviewing angle
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The display is positioned at the lowest point for maximum see-through area but can be dynamically tilted upward through the drive module. This allows the display to maintain its low position for see-through functionality while providing adjustable upward tilting angles to ensure optimal viewing of all display areas when needed.

Inventive Principle:
Principle #15Dynamics
