Solution Overview

Problem

Existing center console assemblies in vehicles do not allow for a tray to be partially extended while maintaining the storage compartment's lower portion covered, and the lid does not effectively conceal both the tray and the compartment in a closed orientation.

Innovation Solution

A center console assembly with a tray that pivots using a friction hinge, allowing partial extension and retraction, and a lid that covers both the tray and the compartment, utilizing a lid hinge for complete closure and exposure, with a biasing spring for easy opening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the tray is completely removed from the storage compartment, then access to the storage compartment is maximized, but the lower portion of the storage compartment is exposed and not covered

Engineering Contradiction:
Improveaccess to storage compartmentVSAvoidcoverage of lower compartment portion
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The tray is designed to be dynamically movable between a fully retracted position (providing maximum access) and a lowered position (covering the lower compartment portion). The friction hinge enables the tray to be positioned at intermediate angles, allowing it to cover the lower portion while still providing access to the upper portion of the storage compartment.

Inventive Principle:
Principle #15Dynamics

2Shape

If the lid is designed to cover the entire storage compartment, then complete concealment is achieved, but the tray cannot be partially extended while maintaining coverage

Engineering Contradiction:
Improveconcealment of tray and compartmentVSAvoidpartial extension capability
Core Design Contradiction:
ShapeVSAdaptability or versatility

Solution Approach 1:

The storage system is segmented into three functional components: the lid (for complete concealment), the tray (for partial extension and selective coverage), and the storage compartment (with upper and lower portions). This segmentation allows each component to perform its specific function independently while working together as a unified system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Both the lid and tray are designed with dynamic movement capabilities through friction hinges. The lid can pivot between open and closed positions to provide complete concealment when needed. The tray can be positioned at various angles to provide partial extension while maintaining coverage of the lower compartment portion, offering adaptability without compromising concealment.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a friction hinge is used for the tray, then the tray can be held at intermediate positions for partial extension, but the mechanism becomes more complex

Engineering Contradiction:
Improveintermediate positioning capabilityVSAvoidhinge mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The friction hinge is designed to be self-regulating, using friction between its components to hold the tray at any desired position without requiring additional locking mechanisms or complex control systems. The user simply applies force to move the tray to the desired angle, and the friction hinge maintains that position automatically.

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If the tray is made movable to provide partial extension, then storage flexibility is improved, but the reliability of covering the lower compartment portion may be compromised

Engineering Contradiction:
Improvestorage flexibilityVSAvoidcoverage maintenance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The tray's dynamic positioning capability allows it to be moved to different angles to provide partial extension while maintaining coverage of the lower compartment portion. The friction hinge ensures that once positioned, the tray remains stable and maintains coverage reliably without drifting to unintended positions.

Inventive Principle:
Principle #15Dynamics

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 the tray to be partially extended for access while keeping the lower compartment portion covered and ensures the lid completely conceals the tray and compartment when closed, enhancing storage flexibility and aesthetics.

AI summary

A vehicle center console includes a tray hinge that supports a tray for pivoting movement about a tray axis, the tray hinge being a friction hinge restricting movement of the tray. The tray is moveable between a lowered orientation where the tray is completely located within a storage compartment and at least partially covering a lower portion of the storage compartment, and a raised orientation at least partially extending out of the storage compartment and exposing the lower portion of the storage compartment. A lid hinge structure is attached to the main body and to a lid such that the lid moves about a lid axis relative to the center console. The lid is movable from a closed orientation covering the storage compartment and the tray, and an open orientation exposing the tray and the upper portion of the storage compartment.
