Reversible Console Box Lid Push-Up Mechanism Without Surface Denting

Solution Overview

Problem

Existing console boxes are limited in their ability to close the upper opening with the lid facing either surface in the thickness direction, failing to accommodate user preferences.

Innovation Solution

A console box design featuring a detachable lid with a lock mechanism and push-up mechanisms that allow the lid to be coupled or decoupled regardless of which surface faces upward, utilizing a striker and urging member to pivot and push up the lid upon unlocking, with softer surfaces to prevent denting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the lid is made with a hard surface to prevent denting, then the surface durability is improved, but the lid cannot be pushed up effectively by the striker

Engineering Contradiction:

Improvesurface durabilityVSAvoidlid push-up effectiveness

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The lid is designed with different hardness levels in different regions: the surface layer (outer layer) is made softer to allow effective pushing by the striker, while the base layer maintains higher strength for structural support. This local quality differentiation resolves the contradiction between surface durability and push-up effectiveness.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The lid employs a composite structure with a base layer and an outer layer of different materials. The base layer provides structural strength, while the outer layer is made of a softer material that can be effectively pushed by the striker. This composite material approach allows the lid to simultaneously achieve both surface durability and ease of operation.

Inventive Principle:

Principle #40Composite materials

2Stability of the object's composition

If the lid is made uniformly hard to maintain shape, then the structural stability is improved, but the surface becomes prone to denting

Engineering Contradiction:

Improvestructural stabilityVSAvoidsurface denting

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The lid is designed with different hardness levels in different regions: the surface layer (outer layer) is made softer to allow effective pushing by the striker, while the base layer maintains higher strength for structural support. This local quality differentiation resolves the contradiction between surface durability and push-up effectiveness.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The lid employs a composite structure with a base layer and an outer layer of different materials. The base layer provides structural strength, while the outer layer is made of a softer material that can be effectively pushed by the striker. This composite material approach allows the lid to simultaneously achieve both surface durability and ease of operation.

Inventive Principle:

3Adaptability or versatility

If the lid is designed to be detachable for versatility, then the adaptability is improved, but the coupling reliability deteriorates

Engineering Contradiction:

Improvedetachable coupling flexibilityVSAvoidcoupling reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The lid is designed as a detachable component separated from the box main body, allowing it to be removed and reattached. This segmentation provides versatility while maintaining reliable coupling through the designed coupling structure between the lid and box main body.

Inventive Principle:

Principle #1Segmentation

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 lid to be securely closed with either surface facing upward without denting, enhancing user convenience and aesthetic appeal by minimizing surface indentation during opening and closing.

Implementation Method 1

AI summary

A console box includes a box main body, a lid, a lock mechanism, and at least one push-up mechanism. The push-up mechanism includes at least one recess that opens in a side surface of the lid, a striker, and an urging member that urges the striker in an urged pivoting direction. The striker includes a first push-up portion and a second push-up portion. The second push-up portion is located on a trailing side of the first push-up portion in the urged pivoting direction, is separated downward from a lower surface of the lid in the closed state, and is brought into contact with the lower surface to apply a push-up force to the lower surface after a push-up action by the first push-up portion.
