Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional headlamp is used to emit fixed light beam patterns, then the structure is simple and cost-effective, but the adaptability to different driving conditions is poor

Engineering Contradiction:

Improveadaptability to different driving conditionsVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The headlamp system is designed to perform multiple functions by integrating various light beam patterns (low beam, high beam, fog light, etc.) and adjustable parameters (luminous intensity, orientation, beam pattern) into a single system. The control module can switch between different operating modes and adjust multiple parameters simultaneously, making the headlamp adaptable to various driving conditions without requiring multiple separate devices

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The headlamp system incorporates dynamic adjustability through the control module that can modify luminous intensity, orientation angles, and beam patterns in real-time based on driving conditions. The system transitions from static fixed patterns to dynamic adjustable parameters, allowing users to customize light output according to actual driving needs such as rain, snow, fog, or nighttime conditions

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the headlamp system is controlled by a portable electronic device via wireless communication, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:

Improveease of controlling headlamp parametersVSAvoidcommunication and control system complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

A portable electronic device (smartphone, tablet, or key fob) serves as an intermediary between the user and the headlamp control module. The portable device runs a control application that communicates wirelessly with the headlamp system, providing an intuitive graphical interface for users to adjust parameters. This intermediary approach simplifies user interaction while keeping the headlamp's internal control logic relatively simple

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical control mechanisms (physical switches, knobs, or buttons on the vehicle) with wireless electronic communication. The control module receives adjustment instructions through wireless signals from the portable electronic device, eliminating the need for complex mechanical interfaces and wiring while improving ease of operation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If multiple beam pattern options and adjustable parameters are implemented, then the adaptability is improved, but the manufacturing cost increases

Engineering Contradiction:

Improvebeam pattern customization capabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent achieves multiple beam patterns and lighting effects by changing control parameters (luminous intensity, orientation angles, beam pattern selection) rather than requiring separate physical components for each mode. The control module adjusts existing light sources through parameter modification, avoiding the need to manufacture additional hardware for each beam pattern option

Inventive Principle:

Principle #35Parameter changes
