Solution Overview

Problem

Head-up display systems require significant memory consumption due to the need for a separate set of deformation data for each direction of projection, which is inefficient and not effectively managed by existing technologies.

Innovation Solution

A head-up display system that uses a single deformation table to define the deformation for multiple directions of projection, allowing for efficient storage and adjustment of the light beam direction without the need for separate deformation data sets for each projection direction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a separate set of deformation data is stored for each direction of projection, then the system can support multiple projection directions, but memory consumption increases significantly

Engineering Contradiction:
Improvenumber of projection directionsVSAvoidmemory consumption
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent merges multiple separate deformation data sets into a single unified deformation table. Instead of storing independent deformation data for each projection direction, the system uses one deformation table that contains all necessary deformation information, significantly reducing memory consumption while maintaining support for multiple projection directions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The unified deformation table serves multiple functions simultaneously - it stores deformation data for all possible projection directions in a single structure. This universal data structure allows the system to handle various projection scenarios without requiring separate specialized data sets for each case.

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

2Manufacturing precision

If separate deformation data sets are used for each projection direction, then accurate deformation correction is achieved, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The patent combines multiple deformation data sets into a single unified deformation table, reducing data management complexity. The unified structure simplifies access and retrieval operations while maintaining the accuracy needed for deformation correction across all projection directions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system uses parameters (such as projection direction angles) to access appropriate deformation data from the unified table. By changing access parameters rather than creating separate data structures, the system maintains precision while reducing complexity.

Inventive Principle:
Principle #35Parameter changes
