Solution Overview

Problem

Existing actuation devices for vehicle doors, particularly sliding doors, do not allow for easy operation of a safety lock from multiple locations, posing safety risks when the door is inclined.

Innovation Solution

A coupling device with a driving mechanism that entrains the third power transmission train when either the first or second actuating element is activated, without transmitting force or motion to the non-actuated elements, allowing simultaneous operation of two organs, such as the door lock, from different actuating elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single actuating element is used to control multiple organs, then device complexity is reduced, but the ability to operate organs from multiple locations is lost

Engineering Contradiction:
Improveactuating device structureVSAvoidmulti-location operation capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The actuating device is segmented into multiple independent actuating elements (first and second actuating elements), each capable of independently controlling the same organ. This segmentation allows the system to maintain simplicity of individual components while achieving multi-location operation capability through the combination of multiple elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention implements multi-functionality by enabling a single organ to be actuated from multiple locations through different actuating elements. The coupling device creates a universal control mechanism where either the first or second actuating element can independently operate the organ, providing versatility in operation locations while maintaining device functionality.

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

2Adaptability or versatility

If multiple power transmission lines are connected to the same organ, then multi-location operation is enabled, but interference between actuating elements occurs

Engineering Contradiction:
Improvemulti-location operation capabilityVSAvoidactuation control accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The coupling device serves as an intermediary mechanism between multiple power transmission lines and the actuated organ. It mediates the control signals from different actuating elements, ensuring that when one element is actuated, the other remains unaffected. This intermediary structure prevents interference while enabling multi-location operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The coupling device implements dynamic control by selectively engaging power transmission lines based on which actuating element is currently actuated. The mechanism dynamically routes the actuation force through the appropriate coupling path, ensuring that only the active actuating element influences the organ while the other remains passive and non-interfering.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a coupling device with driving mechanism is added to enable multi-location operation, then versatility is improved, but device complexity increases

Engineering Contradiction:
Improvemulti-location operation capabilityVSAvoidcoupling device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The coupling device merges multiple power transmission lines into a single control mechanism that acts on one organ. By combining the control paths of multiple actuating elements through a unified coupling structure, the invention achieves multi-location operation capability while consolidating the complexity into a single integrated device rather than requiring separate mechanisms for each actuating element.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention relates to an actuating device (1) with a first and a second actuating element (2, 3), wherein the first actuating element (2) has a flexible first actuating sleeve (6) and a flexible first force transmission string (9) slidably guided therein, and the second actuating element (3) has a flexible second actuating sleeve (17) and a flexible second force transmission string (20) slidably guided therein, and wherein the actuating device (1) has a third actuating element (4) with a third force transmission string (39), which is characterized in that a coupling device (5) with a drive device is provided, which is designed such that, when the first or second force transmission string (9,20) in the direction of actuation (arrow A) causes the third power transmission strand (39) to be carried along in the direction of actuation (arrow A) without carrying along the first or second power transmission strand (9, 20) that is not actuated.
