Motor Vehicle Lock Light Arrangement for Handleless Door Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motor vehicle doors without handles pose a challenge in ensuring user comfort and safety, as it is unclear when it is safe to engage behind the door during the opening process, and existing visual warning systems do not adequately address this issue.
Innovation Solution
A motor vehicle lock arrangement equipped with a light arrangement and a light controller that illuminates during the push-open process and/or upon its completion, providing visual cues to indicate the engagement gap and safe entry, which can be implemented using LED technology for a cost-effective and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If motor vehicle doors are configured without handles to permit large degree of freedom in shaping, then design freedom is improved, but user comfort and safety are worsened because it is unclear when it is safe to engage behind the door
Solution Approach 1:
The patent applies visual warning systems that use color changes (e.g., red, yellow, green lights) to indicate the safety status of door engagement. This allows the door to maintain its handleless design while providing clear visual feedback to users about when it is safe to engage behind the door, thus resolving the contradiction between design freedom and user safety.
Solution Approach 2:
The patent introduces an intermediary visual warning system (light signals, display elements) between the door mechanism and the user. This intermediary communicates the door's safety status without requiring physical handles, allowing the door to maintain its streamlined shape while providing necessary safety information to users.
2Ease of operation
If visual warning systems are implemented to indicate safe engagement time, then user comfort is improved, but device complexity increases
Solution Approach 1:
The patent integrates the visual warning system into existing door control units and uses the same communication infrastructure for multiple functions (door locking, unlocking, and safety indication). This multi-functionality approach reduces overall system complexity while providing comprehensive user information and comfort.
Solution Approach 2:
The visual warning system automatically activates based on door status signals without requiring separate control mechanisms. The system self-regulates by receiving status information from the door control unit and independently determining when to display warning or safety indicators, reducing the need for additional complex control logic.

AI summary
A motor vehicle lock arrangement for a motor vehicle door which is adjustably coupled to a motor vehicle body work, wherein the motor vehicle lock arrangement has a motor vehicle lock wherein the motor vehicle lock arrangement has a push-open arrangement for applying a drive force to the motor vehicle door in its opening direction, so that the motor vehicle door can be adjusted, in a motor-operated push-open process, from a closed door position into a push-open door position which is located further in the opening direction of said motor vehicle door, and as a result an engagement gap can be produced between the motor vehicle door and the motor vehicle body work. It is proposed that the motor vehicle lock arrangement has a light arrangement and a light controller for actuating the light arrangement.
