Solution Overview

Problem

Existing vehicle interior components with movable doors lack a mechanism that allows independent and coupled movements of multiple doors, limiting flexibility and user convenience.

Innovation Solution

A vehicle interior component featuring a base, a cover with two doors, and a link mechanism that enables both doors to move together or independently, using a detent mechanism to maintain or alter the effective length of the link for different positions, allowing coupled and decoupled states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If doors are coupled to move together, then coordination and synchronized operation are improved, but flexibility and independent movement capability deteriorate

Engineering Contradiction:
Improvecoordinated door operationVSAvoidindependent door movement
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The link mechanism transitions between two dynamic states: a coupled state where the link connects both doors to enable synchronized movement, and a decoupled state where the link disconnects to allow independent door operation. This dynamic reconfiguration resolves the contradiction by adapting the coupling behavior based on operational requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the connection parameter between doors by transitioning the link between engaged and disengaged positions. When engaged, the link maintains a fixed effective length to couple door movements; when disengaged, the link allows variable positioning to enable independent door operation, thus resolving the contradiction through parameter variation.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If doors can move independently, then flexibility and accessibility are improved, but coordination and synchronized operation deteriorate

Engineering Contradiction:
Improveindependent door movementVSAvoidcoordinated door operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The link mechanism dynamically switches between coupled and decoupled states based on operational needs. In the decoupled state, each door can move independently to improve accessibility and flexibility; in the coupled state, the link re-engages to restore coordinated movement, thus resolving the contradiction through dynamic reconfiguration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The door system is segmented into independently controllable units, with the link acting as an optional coupling element rather than a permanent connector. This segmentation allows doors to operate independently when needed while maintaining the capability for coordinated operation, resolving the contradiction between flexibility and coordination.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If a link mechanism is added to couple doors, then coordinated movement is improved, but device complexity increases

Engineering Contradiction:
Improvesynchronized door movementVSAvoidlink mechanism structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The link mechanism is designed to automatically transition between coupled and decoupled states based on the relative positions of the doors, without requiring external control systems. The detent mechanism self-activates when the link reaches specific positions, reducing complexity by eliminating the need for motors, sensors, or control electronics.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The detent mechanism acts as an intermediary element that mediates between the link and the door mounting structures. It provides the coupling and decoupling function through simple mechanical engagement features (protrusions and recesses), avoiding the need for complex actuation systems while still achieving the desired coordinated movement capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If the link effective length is changed, then independent door movement is improved, but link mechanism complexity increases

Engineering Contradiction:
Improvedoor position flexibilityVSAvoidlink length adjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The link is segmented into multiple rigid sections that can be rotated relative to each other about pivot points. By rotating these sections, the effective length of the link changes in discrete steps, providing variable door positioning capability while maintaining a relatively simple structure compared to continuously adjustable mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The link effective length is dynamically adjusted based on the operational state. In the coupled state, the link maintains a fixed effective length for synchronized door movement; in the decoupled state, the link can assume different lengths to accommodate independent door positioning, thus achieving flexibility without requiring a continuously variable mechanism.

Inventive Principle:
Principle #15Dynamics
