Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If built-in driving power and control circuit are integrated in each light module, then each module can operate independently, but the device occupies large space and appears bulky
Solution Approach 1:
The patent divides the lighting system into separate functional modules: light modules without integrated drivers, a separate power supply module, and a control module. This segmentation allows each module to be compact while maintaining independent operation capability through modular connectivity.
Solution Approach 2:
The driving power and control circuit are extracted from individual light modules and consolidated into separate dedicated modules. This extraction reduces the volume of light modules while preserving their operational independence through external power and control connections.
2Adaptability or versatility
If high voltage AC power is transmitted between light modules through connection units, then expandability is achieved, but leakage of electricity is possible and electric shock risk cannot be avoided
Solution Approach 1:
The patent changes the electrical parameter from high voltage AC power transmission to low voltage DC power transmission within the modular connection units. This parameter change maintains expandability while eliminating electric shock risk by operating at safe low voltages throughout the distributed system.
Solution Approach 2:
A separate power supply module acts as an intermediary, converting AC power to DC power and distributing it through connection units. This intermediary eliminates direct AC power transmission between modules, reducing electric shock risk while preserving system expandability.
3Ease of operation
If each connected light device has built-in driving circuit and control circuit, then each device can function independently, but multiple manufacturing costs are incurred and it is uneconomical
Solution Approach 1:
The patent implements universal driving and control circuits in separate dedicated modules that can serve multiple light modules simultaneously. This multi-functionality reduces manufacturing costs by eliminating redundant circuits while maintaining independent operation capability of each light module.
Solution Approach 2:
Multiple driving and control circuits are merged into single shared modules that can serve multiple light modules. This consolidation reduces overall manufacturing costs while preserving the independent functionality of each light module through shared resource allocation.
4Device complexity
If control module is positioned right after power module in series connection, then power transmission is simplified, but control flexibility in terms of positioning is limited
Solution Approach 1:
Connection units with integrated control signal routing act as intermediaries, allowing control modules to be positioned anywhere in the series chain while maintaining simplified power transmission paths. The intermediaries route control signals without complicating the power distribution architecture.
Solution Approach 2:
The system is segmented into independent functional blocks (power supply, control module, light modules) connected through standardized interfaces. This segmentation allows the control module to be positioned at various locations in the series connection while maintaining system simplicity through modular connectivity.

AI summary
A modularized LED lighting system includes combinations of a control module, a power module and at least one LED light module, wherein two adjacent modules are detachably connected with a connection unit. A novel design uses a single power module and a control module for transmitting a power or a power and a control signal to one or a plurality of LED light modules with one or a plurality of connection units detachably and remotely connecting the LED light modules. Alternatively, a control module can be integrated with a power module or can be integrated with an LED light module to become a two-module modularized lighting system. The system installation is simple and the designs are coordinated with advantages such as fast assembly, saving assemble time, saving effort, coping with space constraints, a neat appearance, no wire entanglement, and flexibility of extending lighting range.
