Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hardwired light indicators are used, then the lights can be illuminated reliably, but complex wiring is required and electricians are needed for installation
Solution Approach 1:
The patent replaces the mechanical wiring system with an electronic control system. A microcontroller unit (MCU) receives input signals and controls the light indicators through programmable logic, eliminating the need for complex hardwired connections and flasher circuits. The MCU processes input signals and generates appropriate output signals to drive the light indicators, substituting physical wiring complexity with software-based control logic.
Solution Approach 2:
The patent introduces a microcontroller unit as an intermediary between input signals and light indicators. The MCU acts as a mediator that receives input signals, processes them according to stored logic functions, and generates control signals for the light indicators. This intermediary component simplifies the overall system by centralizing control logic and eliminating the need for complex interconnections between inputs and outputs.
2Reliability
If traditional light indicators are used, then the operating status can be indicated, but the lights are quite large in size
Solution Approach 1:
The patent combines multiple functional components into a single integrated indicator device. The microcontroller unit, light indicators, and input signal processing are merged into one compact assembly. This integration allows the device to maintain full functionality while reducing the overall size compared to traditional separate components.
Solution Approach 2:
The patent implements a multi-functional indicator device where a single device can perform multiple functions: indicating different operating statuses through various light colors, implementing different logic functions through programmable control, and accepting multiple input signal types. This universality allows one compact device to replace multiple specialized components, reducing the total area required.
3Reliability
If hardwired flashers are used, then the wiring is fixed and reliable, but the wiring cannot be changed during operation
Solution Approach 1:
The patent implements dynamic reconfigurability through software control. The microcontroller can be programmed with different logic functions and can change its behavior during operation based on input signals. This allows the system to adapt its functionality without physical reconfiguration, maintaining wiring stability while achieving operational flexibility through programmable control logic.
Solution Approach 2:
The patent changes the control parameters from fixed physical wiring to programmable software parameters. The microcontroller stores multiple logic functions that can be selected and executed based on operational requirements. This parameter change approach allows the system to reconfigure its behavior by loading different programs or changing control logic, maintaining reliable physical connections while achieving flexibility through software parameter modification.
4Reliability
If electricians are required for installation, then proper wiring can be ensured, but the installation process becomes time-consuming and complex
Solution Approach 1:
The patent replaces complex mechanical wiring with simplified electronic connections. The standardized input and output connectors allow for quick plug-and-play installation without requiring electricians to perform complex wiring tasks. The microcontroller handles all control logic internally, eliminating the need for external flasher circuits and complex interconnections, thereby reducing installation time while maintaining reliability through standardized connection interfaces.
