Solution Overview

Problem

Existing vehicle interior components lack a mechanism to efficiently coordinate the movement of multiple covers between closed and open positions, leading to inefficient use of storage compartments.

Innovation Solution

A vehicle interior component featuring a base, a first cover, a second cover, and a link with arms and springs that couple or decouple the movement of the covers, allowing one cover to remain open while the other moves to closed, and a spring mechanism to facilitate coordinated movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a link mechanism is added to couple movement of multiple covers, then coordination and usability are improved, but device complexity increases

Engineering Contradiction:
Improvecoordination of cover movementVSAvoidlink mechanism structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The link mechanism is segmented into a first arm and a second arm that can independently rotate about a shaft. This segmentation allows each arm to control one cover separately while still being part of a coordinated system, resolving the contradiction by making the complexity manageable and functional.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The link mechanism acts as an intermediary between the two covers, mediating their movement coordination. The spring-loaded protrusion and depression engagement provides a controlled coupling that coordinates cover movement without requiring direct mechanical connection between the covers themselves.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the link mechanism is configured to always couple movement of covers, then coordination is improved, but flexibility and adaptability worsen

Engineering Contradiction:
Improvecover movement coordinationVSAvoidindependent cover positioning
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The link mechanism transitions from a static coupled state to a dynamic decoupled state through spring-loaded engagement and disengagement of protrusion and depression. This dynamic capability allows the system to adapt between coordinated movement and independent positioning, resolving the contradiction between coordination and flexibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The engagement parameter of the link mechanism changes from engaged to disengaged state. When engaged, the covers move in coordination; when disengaged (via spring compression), the covers can be positioned independently. This parameter change enables the system to switch between operational modes as needed.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If a spring mechanism is added to enable decoupling of cover movement, then flexibility is improved, but device complexity increases

Engineering Contradiction:
Improveindependent cover positioningVSAvoidspring and arm mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spring mechanism serves multiple functions: it enables decoupling of cover movement, provides biasing force for engagement, and allows controlled disengagement. This multi-functionality reduces the need for additional separate mechanisms, making the added complexity worthwhile and efficient.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables efficient use of storage space by allowing one cover to remain open while the other moves to closed, enhancing usability and convenience.

Implementation Method 1

When an external force is applied to move the first cover from the open position toward the closed position, the spring may be compressed to disengage the protrusion and the depression to enable the first arm and the second arm to move relative to one another

Methodology Applied
Scientific EffectSpring compression: Spring

Implementation Method 2

The spring may be configured to bias the first arm to engage the second arm

Methodology Applied
Scientific EffectSpring biasing: Spring

AI summary

A vehicle interior component is disclosed. The vehicle interior component may comprise a base providing a compartment, two covers moveable between closed and open positions and a link to couple and decouple movement of the covers. One of the covers may remain open as the other is closed. The link may comprise two arms; one arm may move relative to the other to enable relative movement of the covers. One arm may comprise a depression and the other may comprise a protrusion to engage the depression to couple movement of the arms. The link may comprise a spring to hold the protrusion with the depression to couple movement of the arms; the spring may compress to enable disengagement of the protrusion and depression to enable relative movement of the covers. The component may comprise at least one of a console, a center console, a floor console.
