Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional wiring methods are used to modify vehicle lamp illumination patterns, then the lamp control function can be achieved, but the installation becomes labor-intensive and expensive

Engineering Contradiction:

Improveinstallation easeVSAvoidwiring complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical wiring system with an electronic communication system. The lamp control device communicates with vehicle systems through communication ports and protocols (such as CAN bus), eliminating the need for extensive physical wiring modifications. This substitution of mechanical connections with electronic communication directly resolves the contradiction by reducing installation complexity while maintaining full control functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If conventional wiring methods are used to modify vehicle lamp illumination patterns, then the lamp control function can be achieved, but the installation becomes time-consuming

Engineering Contradiction:

Improveinstallation speedVSAvoidinstallation time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

By replacing mechanical wiring with electronic communication ports and protocols, the installation process is dramatically accelerated. The communication-based approach allows for rapid connection and configuration without the time-consuming tasks of wire routing, connector installation, and electrical tape application that characterize conventional wiring methods.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If conventional wiring methods are used to modify vehicle lamp illumination patterns, then the lamp control function can be achieved, but the configuration becomes permanent or semi-permanent and cannot be easily enabled or disabled

Engineering Contradiction:

Improveconfiguration flexibilityVSAvoidinstallation complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic configuration capability where the lamp control function can be easily enabled or disabled through software control rather than permanent physical modifications. The communication-based system allows the control device to be programmatically activated or deactivated, providing adaptability without requiring complex installation modifications. This dynamic approach resolves the contradiction by making the system flexible while keeping the installation relatively simple.

Inventive Principle:

Principle #15Dynamics

4Ease of manufacture

If conventional wiring methods are used to modify vehicle lamp illumination patterns, then the lamp control function can be achieved, but the installation cost increases

Engineering Contradiction:

Improveinstallation easeVSAvoidmaterial cost

Core Design Contradiction:

Ease of manufactureVSQuantity of substance

Solution Approach 1:

The patent substitutes mechanical wiring materials (wires, connectors, electrical tape, mounting hardware) with electronic communication interfaces that utilize existing vehicle communication infrastructure. This substitution dramatically reduces material costs while simplifying the installation process, directly resolving the contradiction between installation ease and material consumption.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Systems, methods, and computer-readable media for configuring automotive lamp illumination control are provided. One example method includes, at a computing device, generating a graphical user interface for configuring at an automotive lamp illumination pattern. The graphical user interface includes user input elements and is displayed by way of a display device. An input command is received by way of at least one of the plurality of user input elements. The input command corresponds to the at least one of the user input elements. A message is transmitted to an automotive lamp control device by way of a communication path including a first communication port of the computing device and a second communication port of the automotive lamp control device, based on the received input command. The message is received at the automotive lamp control device, and an action is performed in response to receiving the message.
