Solution Overview

Problem

Conventional hinged lid packages for tobacco and smoking articles automatically close due to inherent forces, making it difficult to keep them open for offering elongate articles in an appealing manner without manually holding them.

Innovation Solution

A hinged lid package design featuring a body with a rear wall, bottom wall, and side walls, where the lid is hinged to the body with a first hinge, and includes a connecting flap created by cuts or weakening lines in the rear wall, allowing the lid to rest on the package in an open position, providing stability and accessibility to the articles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the lid is hinged to the body with inherent closing forces, then the package automatically closes, but the package cannot remain open for appealing presentation

Engineering Contradiction:

Improveautomatic closing functionVSAvoidability to remain open for presentation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The hinge system transitions from a simple closing mechanism to a dynamic system with multiple stable positions. The lid can rest in an open position on the front wall or close automatically, providing operational flexibility that resolves the contradiction between automatic closing and presentation capability

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The front wall of the body acts as an intermediary support surface for the lid in the open position. This mediator element allows the lid to be held open without active force, enabling appealing presentation while maintaining the automatic closing function when not supported

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the lid is held open manually, then the package can be presented appealingly, but continuous manual holding is required

Engineering Contradiction:

Improveappealing presentation positionVSAvoidmanual intervention requirement

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The lid supports itself in the open position by resting on the front wall of the body, eliminating the need for manual holding. This self-service mechanism allows the package to maintain an appealing presentation position without continuous human intervention

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The front wall is pre-configured as a support surface during package design, so when the lid is opened, it naturally has a place to rest. This preliminary preparation of the support structure enables automatic positioning without ongoing manual action

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the lid is opened completely, then all articles are accessible, but the lid may not remain stable in the open position

Engineering Contradiction:

Improveaccess to all articlesVSAvoidlid stability in open position

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The hinge and support structure are designed so that the lid's open position resting on the front wall is an equipotential stable state. The gravitational and elastic forces are balanced in this position, allowing the lid to remain stable when fully open without requiring additional support

Inventive Principle:

Principle #12Equipotentiality
