Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If numerous assembly components are used to achieve large size and high resolution, then display quality is improved, but assembly complexity and production difficulty increase
Solution Approach 1:
The backlight module is divided into two independent sets (first set and second set), each with its own driving module and connection lines. This segmentation allows for modular assembly where each set can be handled separately, reducing overall assembly complexity while maintaining high resolution through the combined effect of multiple lamp bars
Solution Approach 2:
The patent employs asymmetric arrangement where the first and second sets of lamp bars are positioned at different locations relative to the display panel, with each set having independent driving modules. This asymmetric design optimizes light distribution for high resolution while the independent structure simplifies assembly by allowing separate installation of each set
2Area of stationary object
If numerous assembly components are used to achieve large size and high resolution, then display quality is improved, but production difficulty increases
Solution Approach 1:
The large-area backlight module is segmented into two independent sets of lamp bars, each manageable in size. This segmentation enables standardization of production processes for each set, making manufacturing easier while achieving large overall display area through combination
Solution Approach 2:
The first and second connection lines are designed with identical specifications and can be interchangeably used for both sets of lamp bars. This universality simplifies production by allowing the same components to serve multiple functions, reducing the variety of parts needed and easing manufacturing complexity
3Reliability
If different connection lines are used for first and second lamp bars, then connection reliability is improved, but bill of materials complexity increases
Solution Approach 1:
The connection lines for both first and second lamp bar sets are designed with identical specifications, allowing the same component type to be used universally. This reduces bill of materials complexity by eliminating the need for multiple different connection line variants while maintaining reliable connections through standardized design
Solution Approach 2:
The patent employs homogeneous connection lines with identical specifications for both lamp bar sets. This homogeneity simplifies the bill of materials by using a single type of connection line, reducing inventory complexity and making procurement easier while ensuring consistent connection quality across all lamp bars
