Solution Overview

Problem

Conventional dispenser boxes for stackable sheet materials, such as wipes, face challenges in displaying information effectively while maintaining stackability and space efficiency, as they often require distorted stacking or bulky shapes that hinder retail display and storage.

Innovation Solution

A dispenser box with non-rectangular, 'leaf-shaped' end walls and partly curved main walls that accommodate conventional rectangular stacks with minimal distortion, offering increased printable surface area for improved display and ease of handling, while maintaining stability and cost-effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a conventional rectangular box is used, then stackability and space efficiency are improved, but the exposed surface area for information display is reduced

Engineering Contradiction:

Improveexposed surface areaVSAvoidrectangular shape

Core Design Contradiction:

Area of stationary objectVSShape

Solution Approach 1:

The patent applies curvature to the end walls of the dispenser box, transforming them from flat rectangular surfaces to curved surfaces with rounded corners. This curvature increases the exposed surface area available for information display while maintaining a compact form factor suitable for retail shelving.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Area of stationary object

If rounded surfaces are used to increase exposed area, then information display is improved, but the ability to accommodate rectangular stacks and maintain stackability is worsened

Engineering Contradiction:

Improveexposed surface areaVSAvoidaccommodation of rectangular stacks

Core Design Contradiction:

Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by curving only the end walls while keeping the main body walls rectangular and flat. This localized curvature allows the box to accommodate rectangular stacks of wipes effectively while still providing increased exposed surface area for information display on the curved end surfaces.

Inventive Principle:

Principle #3Local quality

3Ease of manufacture

If a rectangular box is used, then manufacturing simplicity is improved, but material consumption increases

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidmaterial consumption

Core Design Contradiction:

Ease of manufactureVSLoss of substance

Solution Approach 1:

The curved end walls are designed to be formed from standard rectangular cardboard blanks using conventional manufacturing techniques such as die-cutting and folding. This approach reduces material consumption by optimizing the use of the blank material while maintaining manufacturing simplicity through the use of standard production processes.

Inventive Principle:

Principle #14Spheroidality (Curvature)

AI summary

A dispenser box having a modified rectangular shape with leaf-shaped end walls and partly curved main walls that may form symmetrically or non-symmetrically configured halves of the dispenser box. The first main wall has a substantially flat surface extending from a first side edge of the dispenser box and changing into a curved surface when moving in a direction from the first side edge towards a second side edge of the dispenser box. The second main wall has a corresponding substantially flat surface at the second side edge, which changes into a curved surface when moving in a direction towards the first side edge.
