Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing jar packages for cosmetics lack an anti-rotate lug, leading to instability and potential skewing or spinning of the inner jar during use.

Innovation Solution

A replaceable jar package design featuring a continuous undercut on the inner jar rim and annular snap beads on the outer jar, combined with a push-to-release button, which secures the inner jar radially and prevents rotation through stabilizing ribs and notches, allowing for easy removal and reassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the inner jar is secured to the outer jar using a snap-fit joint, then the inner jar is held in place, but the inner jar can rotate or spin during use

Engineering Contradiction:

Improvestability of inner jarVSAvoidprevention of rotation

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent introduces asymmetric anti-rotate lugs with stabilizing ribs and notches that prevent rotation of the inner jar within the outer jar. These lugs create a non-circular engagement pattern that mechanically blocks rotational movement while maintaining the snap-fit securement.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The patent adds a rotational constraint dimension to the existing radial snap-fit joint. By incorporating anti-rotate lugs with stabilizing ribs that extend in a direction perpendicular to the snap-fit engagement, the design prevents rotation without interfering with the radial securing function.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If the inner jar is securely fixed to prevent rotation, then stability is improved, but the complexity of the securing mechanism increases

Engineering Contradiction:

Improvestability of inner jarVSAvoidcomplexity of securing mechanism

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into integrated structures: the anti-rotate lugs are formed as integral parts of the inner jar rim, and the stabilizing ribs are incorporated directly into the snap-fit joint structure. This merging reduces the number of separate components while achieving both securement and rotation prevention.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The snap-fit joint structure serves multiple functions: it provides radial securement of the inner jar, incorporates anti-rotate lugs for rotation prevention, and includes stabilizing ribs for positional stability. This multi-functionality reduces overall mechanism complexity by eliminating the need for separate rotation-prevention components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A replaceable jar package includes a push-to-release button, an inner jar sized to fit within the outer jar, the outer jar having a threaded opening at its top and having an opening at its bottom, and having a pair stubs for holding the push-to-release button within the opening at the bottom of the outer jar. The outer jar cooperates with the inner jar to form a snap feature. The inner jar is secured to the outer jar when the snap feature is engaged. The inner jar can be removed from the outer jar when the snap feature becomes disengaged. The snap feature is disengaged by the push-to-release button moving in a direction from the bottom of the outer jar toward a top of the outer jar such that the push-to-release button moves the inner jar relative to the outer jar.
