Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headlamp systems require high maintenance efforts and manufacturing costs due to complex light algorithms that need to be adapted to specific headlamp optical properties, limiting flexibility and reliability.
Innovation Solution
A procedure where a central interface device or control unit processes non-headlamp-specific light pattern information, converting it into headlamp-specific information for pixel control, allowing for headlamp-independent light algorithm development and use across different headlamp variants, reducing the need for headlamp-specific parameter consideration.

Engineering Contradiction Analysis
1Reliability
If light algorithms are adapted to specific headlamp optical properties, then headlamp-specific control information can be accurately determined, but maintenance effort and manufacturing costs increase significantly
Solution Approach 1:
The patent extracts headlamp-specific parameters from the light algorithm calculation process. Instead of adapting the entire light algorithm to each headlamp type, only the parameters (such as optical properties, pixel characteristics) are extracted and used as input data. This separates the universal light algorithm from headlamp-specific characteristics, reducing maintenance complexity while maintaining accuracy.
Solution Approach 2:
The patent creates a universal light algorithm that can be applied to multiple headlamp types without adaptation. By using headlamp-specific parameters as inputs rather than hardcoding headlamp-specific logic, the same light algorithm serves multiple headlamp variants, reducing manufacturing costs and maintenance effort while preserving calculation accuracy.
2Ease of operation
If central electronic units calculate light algorithms for multiple headlamps, then centralized control is achieved, but communication effort and system complexity increase
Solution Approach 1:
The patent extracts only the essential headlamp-specific parameters and transmits them centrally, rather than transmitting complete headlamp control data. This parameter extraction approach maintains centralized control capability while significantly reducing the amount of data that needs to be communicated between the central electronic unit and headlamps.
3Manufacturing precision
If headlamp-specific parameters are always considered in light algorithms, then accurate pixel control is achieved, but flexibility and adaptability of the system decrease
Solution Approach 1:
The patent changes the approach from adapting the light algorithm structure to different headlamp types to changing only the parameter values (headlamp-specific parameters) while keeping the algorithm structure constant. This allows the same light algorithm to be used across different headlamp variants by simply inputting different parameters, thereby maintaining both accuracy and flexibility.
