Solution Overview
Problem
Conventional backlight systems in vehicles require multiple components to maintain functionality, making it difficult to reduce production costs without compromising performance, leading to reduced consumer satisfaction due to simplified designs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple components are used in backlight systems to maintain functionality, then reliability and functionality are preserved, but device complexity and production cost increase
Solution Approach 1:
The patent combines the backlight control function with the existing primary subsystem control circuitry. The controller integrates both the first instruction for the primary subsystem and the second instruction for the backlight subsystem into a single signal, eliminating the need for separate dedicated backlight control components and reducing overall system complexity while maintaining full functionality of both subsystems
Solution Approach 2:
The controller is designed to perform multiple functions: it controls both the primary subsystem (first function) and the backlight subsystem (second function) using a single integrated control mechanism. This multi-functional approach allows one component to replace what would traditionally require multiple separate components, reducing device complexity without sacrificing reliability
2Ease of manufacture
If components are reduced to lower production cost, then manufacturing efficiency improves, but functionality is compromised
Solution Approach 1:
By merging the backlight control functionality into the existing primary subsystem control circuitry, the patent eliminates redundant components that increase production cost. The integrated approach uses the same controller and signal pathways for both primary and backlight functions, simplifying manufacturing while preserving complete functionality through sophisticated signal processing rather than component reduction
Solution Approach 2:
The controller achieves multi-functionality by generating a single signal that simultaneously controls the primary subsystem and the backlight subsystem. This universal control mechanism allows the system to maintain full functionality of multiple subsystems using a single control component, thereby reducing production costs associated with multiple dedicated controllers while preserving all required functions
3Device complexity
If a single signal controls both primary and backlight functions, then device complexity is reduced, but signal processing complexity increases
Solution Approach 1:
The single control signal is segmented into distinct instruction portions: a first instruction for the primary subsystem and a second instruction for the backlight subsystem. The controller processes this segmented information to trigger appropriate operations in each subsystem, allowing complex multi-function control to be achieved through structured signal segmentation rather than requiring multiple separate physical signals
Solution Approach 2:
The controller acts as an intermediary that receives the single signal containing both first and second instructions, processes them separately, and triggers the appropriate operations in the primary subsystem and backlight subsystem. This intermediary processing approach manages the complexity of coordinating multiple functions within a single signal framework without requiring complex direct interactions between subsystems
