Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional filament-type LED lamps use multiple wire connections to connect LEDs to external sources, then the lighting function can be achieved, but the number of wire connections increases leading to poor contact, frequent failures, and reduced reliability
Solution Approach 1:
The patent combines power signal transmission and control signal transmission into a single wire connection between the lighting assembly and external source. The receiver integrates both power reception and control signal reception in one component, eliminating the need for separate wires for each function. This merging reduces the number of wire connections from multiple to just one, directly addressing the contradiction by improving contact stability while reducing device complexity.
Solution Approach 2:
The receiver component serves multiple functions simultaneously: it receives power signals from the external source, receives control signals for LED driving parameters, and processes both types of signals to control the LEDs. This multi-functionality allows a single wire connection to handle what would traditionally require multiple dedicated connections, thereby improving reliability while reducing the number of connections needed.
2Reliability
If conventional filament-type LED lamps use manual welding for wire connections, then the lighting device can be assembled, but the welding technology requirement is high leading to unstable welding and poor contact
Solution Approach 1:
The patent replaces the mechanical welding process with a connector-based electrical connection system. The receiver and driver components are connected to the LED module and external source through standardized connectors that accept wire connections without requiring welding. This substitution eliminates the need for manual welding technology while maintaining stable electrical connections, directly resolving the contradiction between welding stability and ease of manufacture.
3Ease of manufacture
If conventional filament-type LED lamps have complex structure with multiple components, then the lighting function can be achieved, but the appearance aesthetic degree is reduced and production cost increases
Solution Approach 1:
The patent merges the receiver, driver, and LED module into an integrated lighting assembly unit. The receiver and driver are combined in a single component structure that directly connects to the LED module, eliminating the need for separate components and multiple wire connections. This integration reduces the total number of components while maintaining all necessary lighting functions, thereby reducing production cost and improving appearance aesthetic degree.
Solution Approach 2:
The patent segments the lighting system into three main functional modules: the integrated receiver-driver assembly, the LED module, and the external source connection. This segmentation allows each module to be manufactured and tested independently before final assembly, simplifying the manufacturing process and reducing overall complexity. The modular approach reduces the number of components and assembly steps while maintaining full functionality, directly addressing the contradiction between ease of manufacture and device complexity.
