Solution Overview

Problem

Existing carton designs lack an efficient dispensing feature that allows secure access to contents while minimizing material usage and ensuring the contents remain secure within the carton.

Innovation Solution

A carton design featuring a removable panel detachably connected to one of the side walls, creating a dispenser opening that exposes the ends of the articles for easy removal, while maintaining the articles' secure positioning within the carton.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a removable panel is added to create a dispenser opening, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveaccess to contentsVSAvoidcarton structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The side wall of the carton is segmented into a removable panel and a fixed structure. The removable panel can be detached to create a dispenser opening, allowing selective access to contents while maintaining the integrity of the remaining carton structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The side wall transitions from a static closed structure to a dynamic structure with a removable panel. This allows the carton to adapt between two states: fully enclosed for secure transport and partially open for dispensing, improving operational flexibility.

Inventive Principle:
Principle #15Dynamics

2Productivity

If articles are arranged in nested rows, then productivity is improved, but manufacturing precision is worsened

Engineering Contradiction:
Improvearticle arrangement efficiencyVSAvoidarticle positioning
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

Articles are arranged in nested rows where inner rows are positioned within the structural framework created by outer rows. This nesting arrangement maximizes space utilization and allows efficient stacking while the carton's rigid panel structure provides reference points that facilitate precise positioning during assembly.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Loss of substance

If material usage is minimized, then loss of substance is improved, but strength is worsened

Engineering Contradiction:
Improvematerial wastageVSAvoidcarton strength
Core Design Contradiction:
Loss of substanceVSStrength

Solution Approach 1:

The carton is constructed from separate panel elements that are joined together. This segmentation allows for optimized material distribution, using material only where structurally necessary, reducing overall material usage while maintaining strength at critical junctions through proper joining methods.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the carton structure have different material properties or thicknesses optimized for their specific functions. Critical load-bearing areas use more material or stronger construction, while non-critical areas use minimal material, achieving overall strength with reduced total material consumption.

Inventive Principle:
Principle #3Local quality
