Tobacco Package With Nested Shell and Sound Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packages for tobacco-related articles require both hands to open and close, and existing noise-producing mechanisms are expensive to manufacture.
Innovation Solution
A package design featuring a swivelly connected lid and an inner shell that can be moved within an outer shell, incorporating a cost-effective sound-producing mechanism with a protrusion on the inner shell interacting with a counterpart on the outer shell, allowing one-handed operation and producing an attention-catching sound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional package design with a lid swivelled about a hinge line is used, then the package structure is simple and manufacturing is easy, but both hands are required to open and close the package
Solution Approach 1:
The inner shell is nested within the outer shell, with the inner shell being shiftably mounted in the outer shell. This nested structure allows the inner shell to be moved independently to provide access to smoking articles, enabling one-handed operation while maintaining a compact overall package structure
Solution Approach 2:
The package introduces dynamic elements including the shiftably mounted inner shell that can move between retracted and advanced positions, and the lid that can swivel between closed and opened states. These dynamic components enable flexible one-handed operation without significantly complicating the overall structure
2Ease of manufacture
If a noise-producing mechanism with a tab and counterpart is added to produce sound, then attention-catching sound is achieved, but manufacturing cost increases
Solution Approach 1:
The sound-producing mechanism is merged with the existing structural components of the package. The protrusion is integrated into the inner shell and the counterpart into the outer shell, so that the sound-producing function is achieved without adding separate dedicated components, thereby controlling manufacturing costs
Solution Approach 2:
The sound-producing mechanism uses simple, inexpensive protrusions and counterparts that can be easily manufactured into the shell structures. These simple geometric features require minimal additional manufacturing steps and materials, keeping the cost increase minimal while providing the desired sound effect
3Ease of operation
If the inner shell is made shiftably mounted to enable access to smoking articles, then one-handed operation is enabled, but the package structure becomes more complex
Solution Approach 1:
The inner shell is nested within the outer shell with shiftable mounting, allowing independent movement of the inner shell to provide access to smoking articles. This nesting approach enables one-handed operation while maintaining a compact overall package structure
Solution Approach 2:
The package is segmented into an outer shell and an inner shell that can move independently. This segmentation allows the inner shell to be shifted separately to access smoking articles, enabling one-handed operation without requiring complex overall package restructuring
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
Enables convenient one-handed operation and an unusual sound that serves as feedback, while maintaining a moderate price point and attractive appearance.
Implementation Method 1
a sound-producing mechanism adapted to produce a sound when the inner shell is moved from the retracted position to the advanced position or from the advanced position to the retracted position

AI summary
A package for tobacco-related articles including an outer shell, a swivelable lid, and an inner shell adapted to accommodate a plurality of smoking or tobacco-related articles and mounted in the outer shell. The inner shell is moveable towards the top side of the outer shell from a retracted position to an advanced position, which enables access to the smoking articles. A sound-producing mechanism produces a sound when the inner shell is moved from the retracted position to the advanced position and/or in the other direction. The sound-producing mechanism includes at least one part arranged at the inner shell, which interacts in a sound-producing manner with a counterpart arranged at an inner face of the outer shell.
