Cigarette Box with Nested Push-Up Case and Hinged Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cigarette boxes with hinged lids lack visual appeal and user motivation due to their standard opening and closing mechanisms.
Innovation Solution
A cigarette box design featuring an inner case with a partial top opening and an outer case that allows the inner case to stick out, equipped with a hinged cap that opens and closes via a self-hinge mechanism, providing a novel and distinctive opening and closing mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conventional hinged lid package is used, then the structure is simple and easy to manufacture, but the visual attraction and user buying motivation are poor
Solution Approach 1:
The patent employs a nested structure where an inner case is placed within an outer case. The inner case can be pushed upward to stick out of the outer case, creating a dynamic visual effect. This nesting mechanism provides visual attraction while maintaining reasonable structural complexity through the coordinated design of the inner and outer cases.
Solution Approach 2:
The patent introduces dynamic elements to the packaging system. The inner case can move upward and stick out of the outer case, and the hinged cap can rotate to open and close the access opening. These dynamic movements transform the static conventional package into an interactive system that increases visual attraction and user engagement.
2Ease of operation
If a standard hinged lid is used, then the manufacturing process is simple, but the accessibility and user experience are ordinary
Solution Approach 1:
The patent divides the packaging into distinct functional segments: an inner case for containing the inner pack, an outer case for enclosure, and a hinged cap for opening and closing. Each segment has a specific function, and their coordinated operation provides improved accessibility. The segmentation allows for relatively simple manufacturing of each component that can be assembled together.
Solution Approach 2:
The hinged cap acts as an intermediary mechanism between the user and the inner pack. It provides a user-friendly interface with an access opening that can be opened and closed through the sticking-out inner case, improving ease of operation. The intermediary design balances user experience with manufacturing feasibility by using a rotatable cap mechanism rather than complex latches or locks.
3Shape
If the inner case is pushed upward to stick out, then the visual appeal increases, but the structural stability may be compromised
Solution Approach 1:
The patent accepts dynamic movement as a feature rather than a compromise. The inner case is designed to be pushed upward and stick out of the outer case, and this dynamic position provides visual appeal. The hinged cap rotates to accommodate this movement, and the guide walls ensure controlled motion. The system maintains stability through the coordinated dynamic interaction of its components rather than rigid fixed positions.
Solution Approach 2:
The guide walls act as intermediary elements that control and constrain the movement of the inner case and hinged cap. They ensure that the inner case sticks out in a controlled manner and that the hinged cap rotates along a proper path. This intermediary guidance maintains structural stability during the dynamic opening operation while allowing the visual appeal of the sticking-out configuration.

AI summary
A cigarette box includes an inner case (2) enclosing a filter-cigarette inner pack and having an access opening (4) at the top thereof, and an outer case (8) enclosing the inner case (2) and having a push window (10) at the bottom thereof. The outer case (8) has a hinged cap (12). In a closed position, the hinged cap (12) closes the access opening (4) of the inner case (2). When the inner case (2) is pushed upward through the push window (10) to stick out of the outer case (8), the hinged cap turns around a hinge (14) from the closed position to an open position in the manner associated with the sticking-out of the inner case, thereby opening the access opening (4) of the inner case (2) .
