Solution Overview

Problem

Modern motor vehicles lack an efficient and safe means to provide information to drivers and other road users about the vehicle's condition and surroundings before entering or while operating the vehicle, and to enhance road safety through intuitive and robust communication and control elements.

Innovation Solution

A multifunction tape is integrated into the vehicle's body as a strip-shaped cladding element, capable of displaying and outputting independent information, including acoustic signals, with actuator and sensor components, and serving as an operating element, to enhance driver and road user awareness and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If multiple display and input elements are integrated into the vehicle interior (dashboard, center console), then information can be provided to the driver, but the driver cannot access this information before entering the vehicle

Engineering Contradiction:
Improveaccess to vehicle informationVSAvoidpre-entry information access
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent applies preliminary action by enabling the driver to access vehicle information (such as climate control settings, media playback status, and vehicle status) through the trim strip on the exterior of the vehicle before entering the vehicle. This allows the driver to review and prepare vehicle settings in advance, eliminating information access delays upon entry.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If traditional buttons and switches are used for vehicle operation, then control functions are available, but the operating elements are not visible and accessible when the driver is outside the vehicle

Engineering Contradiction:
Improvecontrol element accessibilityVSAvoidcontrol element visibility
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent applies dimensionality change by moving the control elements from the interior three-dimensional space (dashboard, center console) to the exterior surface of the vehicle. The trim strip serves as an external interface that provides both display and input capabilities on the vehicle's outer surface, making controls visible and accessible from outside the vehicle.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Loss of information

If display elements are integrated into the vehicle body, then information can be projected for road users, but the display elements increase device complexity

Engineering Contradiction:
Improveinformation communication to road usersVSAvoiddisplay element integration
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies multi-functionality by designing the trim strip to simultaneously serve as a structural cladding element, a display device for road users, and a control interface for the driver. This single component performs multiple functions: providing information to pedestrians, displaying vehicle status, and enabling external control operations, thereby reducing overall system complexity despite the added capabilities.

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