Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an embedded IPS controller is integrated into the LED lighting device, then the device can provide IPS functionality, but the deployment flexibility and upgrade capability are limited
Solution Approach 1:
The system is divided into separate functional modules: the existing LED lighting device and the add-on IPS controller. The controller contains the IPS functionality including two-way wireless module and VLC module, while the LED device maintains its lighting function. This segmentation allows independent deployment and upgrading of the IPS controller without replacing the entire lighting device.
Solution Approach 2:
The IPS controller functionality is extracted from the conceptual embedded design and implemented as a separate add-on device. The controller can be attached to existing LED lighting devices, enabling IPS functionality without modifying or replacing the original lighting device, thus improving deployment flexibility.
2Adaptability or versatility
If the entire LED lighting device is replaced to add IPS functionality, then new functionalities are achieved, but cost increases and environmental waste is generated
Solution Approach 1:
The add-on IPS controller merges with the existing LED lighting device to create a combined system with both lighting and IPS functionalities. The controller attaches to the existing device rather than replacing it, preserving the original lighting components and reducing material waste while achieving enhanced functionality.
Solution Approach 2:
Instead of discarding the existing LED lighting device when adding IPS functionality, the system recovers and reuses the original lighting device by attaching the add-on controller. This approach prevents the LED device from becoming waste while still achieving the desired functionality enhancement.
3Reliability
If an embedded IPS controller is used, then the device is self-contained, but upgradeability is prevented as the entire device must be replaced
Solution Approach 1:
The system transitions from a static embedded controller design to a dynamic add-on controller design. The add-on controller can be independently upgraded, replaced, or modified without affecting the core LED lighting device, enabling continuous improvement of IPS functionality while maintaining system reliability.
Solution Approach 2:
The add-on controller is designed with preliminary upgrade paths in mind, allowing future enhancements to IPS functionality without requiring replacement of the entire system. The modular design anticipates future upgrades by separating the IPS functionality from the lighting device.
4Device complexity
If conventional embedded IPS controller design is used, then the device structure is simplified, but deployment cost increases due to replacement requirements
Solution Approach 1:
The add-on IPS controller acts as an intermediary between the existing LED lighting device and the IPS network. It interfaces with the device through standard power and data connections, enabling IPS functionality without requiring complex modifications to the original device structure or expensive complete replacements.

Function Achieved in This Case
Enables the addition of new functionalities to LED lighting devices without replacement, allowing for incremental upgrades and cost-effective product differentiation, while reducing environmental waste and maintaining existing device functionality.
Implementation Method 1
Popular Light Intensity Baseband Modulation (LIBM) includes On-Off Keying (OOK), Pulse Amplitude Modulation (PAM), and Pulse Position Modulation (PPM). The technology transmits data by adjusting the intensity or the on-off cycle of the visible light.
Implementation Method 2
a new technology, Visible Lighting Communication (VLC), enables IPS data broadcasting via LED light according to the fixture's physical location.
Implementation Method 3
Inside the IPS receiver device, there is a photo diode for receiving the VLC data
