Solution Overview

Problem

Existing display systems face a decrease in correction accuracy due to fixed processing order between vibration correction and image correction, leading to increased positional deviation of display content, especially under varying vehicle conditions and processing time constraints.

Innovation Solution

The display system dynamically switches the order of processing between vibration correction and image correction based on the image processing time and detected vibration frequencies, optimizing the order to minimize delay and error in correcting the display position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a fixed processing order between image correction and vibration correction is used, then the system structure is simple, but positional deviation of display content increases under varying vehicle conditions

Engineering Contradiction:
Improvedisplay position accuracyVSAvoidprocessing order complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent implements a dynamic processing order selection mechanism that adapts between two processing sequences (image correction first, then vibration correction; or vibration correction first, then image correction) based on detected vibration frequency characteristics. This dynamic adaptation resolves the contradiction by allowing the system to maintain high display position accuracy under varying vehicle conditions without requiring a completely complex reconfigurable architecture.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the processing parameter (processing order) based on the vibration frequency parameter detected from vehicle motion. When vibration frequency exceeds a threshold, one processing order is selected; when below the threshold, another order is selected. This parameter-based adaptation enables the system to maintain correction accuracy across different driving conditions while using a manageable processing framework.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If image correction processing is performed with high accuracy, then display position accuracy improves, but processing time increases causing delay

Engineering Contradiction:
Improvecorrection accuracyVSAvoidprocessing delay
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent dynamically adjusts the processing sequence based on vibration conditions to optimize the balance between accuracy and speed. By selecting whether to perform image correction or vibration correction first based on real-time vibration frequency detection, the system can maintain correction accuracy while minimizing processing delay in different driving scenarios.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses feedback from vibration frequency detection to determine the optimal processing order. The vibration detection unit continuously monitors vehicle motion and provides feedback that controls the processing sequence selection, enabling the system to adaptively maintain accuracy while managing processing time based on actual driving conditions.

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If vibration correction is performed continuously, then positional deviation is suppressed, but processing load and time consumption increase

Engineering Contradiction:
Improvepositional deviation suppressionVSAvoidprocessing efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent implements periodic vibration correction by detecting vibration frequency characteristics and selectively applying correction processing only when vibration exceeds a threshold frequency. This periodic approach suppresses positional deviation during actual vibration events while avoiding continuous processing during normal driving conditions, thereby improving processing efficiency.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system changes the correction processing parameter based on vibration frequency parameters. When vibration frequency is above a threshold, vibration correction processing is activated; when below the threshold, the processing is skipped or reduced. This parameter-based control maintains positional accuracy during vibration while improving overall processing efficiency.

Inventive Principle:
Principle #35Parameter changes
