Solution Overview

Problem

Traditional sliding door systems on vehicles require a two-step operation for opening and closing due to the transition from a linear guide rail to a curved guide rail, resulting in disrupted motion and space constraints in vehicles with limited mounting surfaces.

Innovation Solution

A simultaneous movement system for vehicle doors utilizing first and second primary hinge arms and secondary hinge arms, with guide track and rail regions, allowing the door to travel smoothly along both guide tracks and rails simultaneously, minimizing space requirements and enabling continuous motion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional sliding door system uses separate linear and curved guide rails, then the door can be guided through opening and closing movements, but the motion is disrupted and the operation becomes two-step rather than simultaneous

Engineering Contradiction:
Improvedoor operation smoothnessVSAvoidguide rail configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the linear guide rail and curved guide rail into a single integrated guide structure. The guide rail includes both a linear portion and a curved portion that are connected and work together as one continuous path, allowing the door to transition smoothly from sliding to articulating motion without disruption. This merging eliminates the need for separate guide rail systems and the complex transition mechanism between them.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The guide rail incorporates a curved portion that provides the necessary articulation path for the door. By using a curved guide rail section instead of a purely linear path, the system enables the door to follow a smooth arc-shaped trajectory during opening and closing, eliminating the sharp transitions and disruptions that would occur with separate linear and curved guide rails.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Reliability

If the guide rail is mounted on the vehicle body class A surface, then the door can be guided properly, but it disrupts the class A surface and consumes mounting space

Engineering Contradiction:
Improvedoor guidanceVSAvoidmounting surface area
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The guide rail system is designed to be mounted in a configuration that utilizes the available space more efficiently. By orienting the guide rail along the length of the door and positioning it to work with the door's natural movement plane, the system provides reliable guidance while minimizing the disruption to the class A surface and reducing the amount of mounting surface area required.

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

3Productivity

If the door transitions from linear track to curved track, then the door can complete its opening and closing cycle, but the two-step operation results in disrupted motion

Engineering Contradiction:
Improvedoor operation efficiencyVSAvoidmotion continuity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The integrated guide rail system provides a continuous, unbroken path for door movement. The linear portion and curved portion are connected in a way that allows the door to transition smoothly from one section to the other without stopping, reversing, or experiencing disrupted motion. This continuous action eliminates the two-step operation problem and improves both productivity and ease of operation.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A simultaneous movement system for a vehicle door is provided. The system includes a simultaneous movement system comprising first and second primary hinge arms, first and second secondary hinge arms, primary and secondary rails and guide track. The second primary hinge arm and the second secondary hinge arm are pivotally mounted to a vehicle body structure on one end and are pivotally mounted to a primary slide and a secondary slide at the other ends respectively. The first primary hinge arm includes a guide track region and a rail region. The primary rail receives a primary slide. The secondary rail receives a secondary slide. The guide track receive the guide track region of the primary hinge arm thereby allowing the primary hinge arm to travel along both the guide track and the primary rail simultaneously through the guide track region and the rail region of the primary hinge arm.
