Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camera arrays in electronic devices face challenges in achieving high integration due to the need for numerous wire harnesses, limiting the number of cameras that can be arranged in a unit area and resulting in a low integration level, especially when combined with display screens.
Innovation Solution
A camera system comprising a main control chip, multiple groups of cameras, and bidirectional differential data lines, where each group of cameras is connected to a main control unit via a pair of bidirectional differential data lines, reducing the number of wire harnesses and enabling higher camera density by using a substrate with characteristic impedance optimized for signal transmission.

Engineering Contradiction Analysis
1Measurement precision
If a camera array is used to achieve good optical imaging effect, then image quality is improved, but the number of wire harnesses increases making high integration difficult
Solution Approach 1:
The patent merges multiple camera modules into a unified camera array system where multiple imaging units share common control and data transmission resources. The main control chip consolidates control functions for multiple cameras, and bidirectional differential data lines provide shared data pathways, reducing the need for separate wire harnesses for each camera while maintaining high imaging quality.
Solution Approach 2:
The bidirectional differential data lines serve multiple functions: they transmit data from multiple cameras to the main control chip, provide clock signals, and enable bidirectional communication. This multi-functional design reduces the overall number of wire harnesses needed while supporting high-density camera arrangements.
2Quantity of substance
If more cameras are arranged in a unit area to increase integration, then camera density is improved, but wire harness management becomes more difficult
Solution Approach 1:
The patent transitions from point-to-point wiring to a bus-based architecture where multiple cameras connect to shared data lines. This dimensional change in connectivity approach allows high camera density without proportional increase in wire harness complexity, as cameras are arranged in arrays that share common data transmission pathways.
Solution Approach 2:
The main control chip acts as an intermediary that manages data from multiple cameras through shared bidirectional differential data lines. This mediator approach allows multiple cameras to communicate efficiently without requiring dedicated wire harnesses for each connection, enabling high integration with manageable complexity.
3Adaptability or versatility
If camera array and display screen are separately provided, then functional independence is maintained, but integration level decreases
Solution Approach 1:
The patent combines the camera array and display screen into a single integrated electronic device structure. The main control chip coordinates both camera operations and display functions, while shared data transmission pathways connect both subsystems to the same control architecture, achieving high integration while maintaining functional independence through software-controlled task allocation.
