Solution Overview

Problem

Conventional door adjustment systems for slidable vehicle doors are complex and time-consuming, making vehicle assembly inefficient, and they fail to ensure a correct door position for a sealed and aesthetically pleasing connection to the vehicle body structure.

Innovation Solution

A door tilting system comprising an inner and outer socket, where the inner socket is rotatably arranged relative to the outer socket, allowing rotational displacement to adjust the receiving opening's direction, facilitated by a locking member that enables secure attachment and detachment, simplifying the adjustment process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional door adjustment systems are used, then door position can be adjusted, but the adjustment process is complicated and time-consuming

Engineering Contradiction:
Improvedoor adjustment processVSAvoidassembly time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The door adjustment system is segmented into multiple independent adjustment mechanisms: longitudinal adjustment via the movable arm structure, lateral adjustment via the door lock latch, and vertical/tilt adjustment via the door tilting system with inner and outer sockets. This segmentation allows each adjustment dimension to be handled independently, simplifying the overall adjustment process and reducing assembly time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The door tilting system employs dynamic adjustment capabilities through the inner socket that can rotate relative to the outer socket, and the movable arm structure that can slide along the rail. These dynamic elements enable continuous adjustment of door position and angle, allowing for precise positioning without complex fixed adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If conventional door adjustment systems are used, then door position can be adjusted, but the system becomes complicated

Engineering Contradiction:
Improvedoor position adjustment capabilityVSAvoidadjustment system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The door lock latch serves multiple functions: it secures the door in the closed position and simultaneously provides lateral adjustment capability. The movable arm structure provides both structural support and longitudinal adjustment. The door tilting system with rotating inner socket provides both structural connection and vertical/tilt adjustment. This multi-functionality reduces the need for separate adjustment mechanisms, simplifying the overall system while maintaining full adjustability.

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

3Adaptability or versatility

If the inner socket is rotatably arranged relative to the outer socket, then the receiving opening direction can be adjusted, but the structural complexity increases

Engineering Contradiction:
Improvereceiving opening direction adjustmentVSAvoidsocket structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The inner socket is nested within the outer socket, with the inner socket's outer surface arranged in connection to the outer socket's inner surface. This nested configuration allows the receiving opening to be adjusted in direction through rotation of the inner socket relative to the outer socket, while maintaining a compact and relatively simple overall structure. The nesting eliminates the need for separate mounting brackets or complex linkage mechanisms.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A door tilting system for a slidable vehicle door, and a method for adjusting a door tilting system, where the door tilting system is forming part of a pivoting joint between the vehicle door and a movable arm structure connecting the vehicle door to a vehicle body structure. The door tilting system comprises an inner socket and an outer socket, where the inner socket is arranged inside the outer socket and rotatably arranged relative to the outer socket. The inner socket comprises a receiving opening configured for receiving a fastening device. The receiving opening has an elongated configuration, and the receiving opening is extending in a first direction along a first axis through the inner socket. The door tilting system is configured for changing the first direction of the receiving opening relative to the outer socket upon rotational displacement of the inner socket relative to the outer socket.
