Solution Overview

Problem

Existing vehicle doors, particularly interior or bulkhead sliding doors in commercial vehicles, require multiple separate mechanisms for easy opening, locking in an open position, and closing, leading to complex systems that are costly, prone to failure, and occupy excessive space.

Innovation Solution

Integration of opening and closing mechanisms onto the door itself, utilizing a single handle that can be manipulated in different directions to actuate separate release mechanisms for opening and closing, reducing external components and potential failure points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate mechanisms are used for opening, locking, and closing the door, then the door can perform all required functions, but the system becomes complex and occupies more space

Engineering Contradiction:

Improvedoor functionalityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate mechanisms (opening mechanism, locking mechanism, and closing mechanism) into a single integrated door assembly. The handle assembly integrates the handle, release mechanisms, and linkages into one unified structure, eliminating the need for separate external mechanisms and reducing overall system complexity while maintaining all required door functions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The handle assembly serves multiple functions simultaneously: it acts as the opening actuator, the locking release, and the closing release. By designing the handle assembly to perform multiple functions through its various components (handle, linkages, release mechanisms), the patent reduces the total number of separate mechanisms needed in the door system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple separate mechanisms are used for opening, locking, and closing the door, then the door can perform all required functions, but the manufacturing and maintenance costs increase

AI summary

Door configurations having integrated mechanisms for opening and releasing for closure, with elements of these mechanisms located on or largely on the body of the door itself. In some embodiments of the disclosure, a door has a handle and two release mechanisms coupled thereto, one of which releases a lock and allows the door to open, and the other of which releases a catch and allows the door to close. The two release mechanisms are coupled to the handle such that manipulating the handle in one direction actuates one of the release mechanisms but not the other, and manipulating the handle in the other direction actuates the other release mechanism. In this manner, manipulating the handle in one direction opens the door, and manipulating the handle in the other direction closes the door.
