Solution Overview

Problem

Conventional compact containers with exposed hinge parts compromise their outer appearance and often have limited hinge rotation due to tight contact between the container body and cover, leading to increased complexity and component count.

Innovation Solution

A container design where the hinge part is internally disposed, utilizing a dual rotating member system with guide protrusions and grooves to allow for stable and adjustable rotation without external exposure, incorporating magnetic members for coupling, and a detachable inner container for enhanced usability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If the hinge part is disposed inside the container body and outer cover, then the outer appearance is improved, but the radius of rotation becomes limited due to tight contact

Engineering Contradiction:
Improveouter appearanceVSAvoidradius of rotation
Core Design Contradiction:
ShapeVSLength of moving object

Solution Approach 1:

The hinge part is divided into two separate rotating members: a first rotating member coupled to the container body and a second rotating member coupled to the outer cover. These members are disposed at different locations and can rotate independently, allowing the hinge mechanism to be hidden while maintaining adequate rotation radius by distributing the rotational components throughout the container structure rather than confining them to a single tight space.

Inventive Principle:
Principle #1Segmentation

2Shape

If the hinge part is disposed inside the container, then the outer appearance is improved, but the number of components increases causing complexity

Engineering Contradiction:
Improveouter appearanceVSAvoidnumber of components
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The first and second rotating members are rotatably coupled to each other, merging their functions into a unified hinge mechanism. This coupling allows the two members to work together as an integrated system that achieves the dual goals of hiding the hinge mechanism while maintaining rotation capability, rather than treating them as separate, independently complex components.

Inventive Principle:
Principle #5Merging (Combining)

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

The solution provides a sophisticated outer appearance, stable and adjustable rotation of the cover and body, reduced component complexity, and easy maintenance by hiding the hinge and locking mechanisms, while allowing for varied rotation radii and easy detachment of inner containers.

Implementation Method 1

a first magnetic member may be disposed on one side of the container body, and a second magnetic member may be disposed on one side of the outer cover, and through a magnetic force between the first magnetic member and the second magnetic member, the outer cover and the container body may be coupled to each other
