Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting devices are inconvenient for patients, the elderly, and children with mobility issues, as they require manual operation and lack flexible control over characteristics like color temperature, dimming, and brightness, and often require replacement of the entire device upon PSU or LED failure.
Innovation Solution
A detachable communication device with a communication module and sensor module that uses infrared sensors for lighting control, allowing for wireless control via ZigBee, WiFi, or Bluetooth, and enabling selective control of lighting characteristics through PWM and UART methods, while being integrated with the lighting module for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication module is integrated with the lighting device, then wireless control functionality is provided, but the entire device must be replaced when PSU or LED fails
Solution Approach 1:
The communication device is designed as a separate, detachable module that can be independently replaced from the lighting device. The communication module includes a communication element (ZigBee, WiFi, or Bluetooth) for wireless control, while the lighting device contains the PSU and LED. When the communication module fails, only the module needs replacement, not the entire lighting device, resolving the contradiction between providing wireless control functionality and avoiding complete device replacement.
2Device complexity
If manual switch operation is used, then the lighting device is simple, but patients, elderly, and children with mobility difficulties cannot operate it
Solution Approach 1:
The mechanical switch operation is replaced with a wireless communication-based control system. The communication element (supporting ZigBee, WiFi, or Bluetooth protocols) enables remote control through a mobile terminal or remote controller, eliminating the need for physical contact with switches. This substitution maintains system simplicity while dramatically improving ease of operation for patients, elderly users, and children with mobility difficulties.
3Adaptability or versatility
If multiple wireless communication schemes are supported, then communication flexibility is improved, but device complexity increases
Solution Approach 1:
The communication element is designed with multi-functionality to support multiple wireless communication schemes (ZigBee, WiFi, and Bluetooth) within a single integrated module. This universal approach allows the lighting device to adapt to different communication environments and requirements without needing separate modules for each protocol, thereby improving communication flexibility while managing device complexity through unified integration.
