Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio/visual devices face challenges in manufacturing efficiency and risk of electrical damage due to incorrect installation of light bars and potential misconnection of power and driving voltage inputs in backlight systems, particularly for liquid crystal display screens.
Innovation Solution
A symmetrical light bar layout is implemented with a daisy-chain configuration, where each light-emitting diode (LED) bar has a communications port at the proximal end and a power port at the distal end, connected by a power and communications cable, with integrated circuit control devices for precise control and reduced wiring, enhancing manufacturing ease and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If light bars are installed in a non-symmetrical configuration with inconsistent port placement, then manufacturing flexibility may be improved, but installation errors increase and manufacturing efficiency decreases
Solution Approach 1:
The backlight system is divided into multiple standardized light bar modules, each with identical port configurations. This segmentation allows for modular assembly where each module follows the same installation protocol, reducing errors while maintaining manufacturing flexibility through standardized interchangeable components.
Solution Approach 2:
The patent applies asymmetry in reverse by deliberately creating symmetry in the light bar configuration. All light bars are positioned with consistent orientation and port placement, creating a symmetrical pattern that eliminates installation confusion. This deliberate symmetry ensures that each light bar connects in the same manner, reducing installation errors while maintaining ease of manufacture through standardized procedures.
2Reliability
If power and driving voltage inputs are connected without standardized port placement, then connection flexibility may be improved, but the risk of electrical damage increases
Solution Approach 1:
The light bars are pre-configured with standardized port placements during manufacturing, with communication ports and power ports positioned at specific locations. This preliminary action ensures that during assembly, workers simply need to connect cables to the predetermined port locations without complex configuration, reducing electrical damage risk while maintaining connection simplicity.
Solution Approach 2:
Different regions of the light bar structure are assigned specific functions with standardized port placements. Communication ports are positioned at one location while power ports are positioned at another, creating distinct connection zones. This local quality differentiation ensures that power and data connections are made to the correct locations, preventing electrical damage while simplifying the overall connection process.
3Ease of manufacture
If light bars are configured with non-uniform orientation, then adaptability to different screen sizes may be improved, but manufacturing complexity and error risk increase
Solution Approach 1:
The standardized light bar design with consistent port placement and orientation creates a universal module that can be adapted to different screen sizes through quantity adjustment rather than configuration change. The same light bar module works across multiple device variants, maintaining manufacturing simplicity while providing adaptability through scalable deployment.
Solution Approach 2:
Instead of changing the orientation or configuration parameters of light bars to adapt to different screen sizes, the patent maintains fixed orientation parameters and adapts through changing the number of light bars deployed. This parameter change strategy keeps each individual light bar simple and standardized while achieving overall system adaptability through quantitative adjustment.
