Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional keyless entry systems are used, then contactless control functionality is achieved, but user experience lacks human-like interaction and welcoming atmosphere

Engineering Contradiction:
Improvehuman-like interaction capabilityVSAvoidillumination system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The illumination modules are made dynamically movable within the headlight assemblies, allowing them to pivot and change orientation to simulate human eye movements. This dynamic capability enables the system to adapt its behavior based on user presence and authorization status, creating a welcoming interaction without requiring complex mechanical structures throughout the entire vehicle

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The illumination modules utilize different light colors and intensities to convey different states and emotions. Authorized users trigger specific illumination patterns with particular color schemes that simulate human facial expressions and gestures, enhancing the perceived human-like interaction through optical rather than mechanical means

Inventive Principle:
Principle #32Color changes

2Ease of operation

If illumination modules pivot to follow user movement, then welcoming effect is enhanced, but mechanical complexity and energy consumption increase

Engineering Contradiction:
Improveuser interaction experienceVSAvoidenergy consumption of pivotable modules
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The illumination modules employ periodic illumination patterns rather than continuous operation. The modules activate in sequences - first detecting user approach, then pivoting to follow movement, and finally returning to neutral position. This periodic action significantly reduces energy consumption compared to continuous operation while maintaining the welcoming effect throughout the interaction sequence

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses the vehicle's existing sensor network and authorization systems to automatically detect and respond to user presence. The illumination modules self-adjust their behavior based on predefined authorization criteria, eliminating the need for additional complex control systems or manual intervention while optimizing energy usage through automated state management

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If multiple illumination sequences are implemented, then humanizing effect is improved, but control system complexity increases

Engineering Contradiction:
Improveillumination sequence varietyVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The illumination system is segmented into multiple independent modules within each headlight assembly, each capable of independent control and movement. This segmentation allows different modules to perform different functions in different sequences - some for detection, others for welcoming gestures, and others for navigation - reducing the complexity of any single control pathway while maintaining overall system versatility

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The same illumination modules serve multiple functions across different operational contexts. The pivotable modules used for welcoming gestures also serve as position lights, turn signals, and navigation indicators. This multi-functionality reduces the need for separate dedicated systems for each function, thereby controlling overall system complexity while achieving diverse illumination sequences

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present invention relates to a method and a device for performing a welcoming illumination in a motor vehicle. Therefore, the problem addressed by the present invention is that of providing a method and a device that allow a welcoming illumination which seems human. According to the invention, a method for performing a welcoming illumination by means of the headlights of a motor vehicle is proposed, each headlight having a pivotable illumination module, the shape of which illumination modules imitates human eyes at least when the illumination modules are illuminated, the method comprising the following steps: —defining an authorization zone having a predefinable radius around the motor vehicle; —registering whether at least one authorized user is within the authorization zone; —starting a first illumination sequence of the welcoming illumination, in which first illumination sequence the illumination modules pivot, with respect to a vehicle coordinate system, from an idle position directed downward to a horizontally oriented driving position; —determining the position of the authorized user within the authorization zone with respect to the vehicle coordinate system; —starting a second illumination sequence of the welcoming illumination, in which second illumination sequence the illumination modules first pivot toward the registered authorized user and subsequently pivot back to the driving position oriented horizontally and forward.
