Cigarette Packet Rear Coupon Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing rigid, hinged-lid packets of cigarettes with coupons often have the coupon covering the pull-off portion of the inner package, making it difficult for smokers to access cigarettes without first removing the coupon, as there is no convenient way to dispose or conserve the coupon.
Innovation Solution
A rigid, hinged-lid packet design where the coupon is positioned in a way that it does not obstruct access to the pull-off portion, allowing users to extract cigarettes without removing the coupon initially, with the coupon being easily detachable when a suitable place is available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the coupon is located inside the outer container at the front between the inner package and outer container, then the coupon is visible and accessible, but it covers the pull-off portion making it difficult to remove without first removing the coupon
Solution Approach 1:
The coupon is divided into two functional parts: a fixed portion attached to the outer container that provides advertising information, and a removable portion that can be detached without removing the entire coupon. This segmentation allows the pull-off portion to be accessed and removed independently while the advertising coupon remains in place.
Solution Approach 2:
The problematic element (the coupon covering the pull-off portion) is extracted or removed from its obstructing position. The coupon is repositioned to the rear of the inner package where it cannot interfere with the pull-off mechanism, eliminating the obstruction while preserving the advertising function.
2Ease of operation
If the coupon is placed at the front to be visible, then advertising effectiveness is improved, but users cannot access cigarettes conveniently without removing the coupon first
Solution Approach 1:
The coupon is segmented into fixed and removable portions, allowing users to access cigarettes immediately by removing only the necessary part while the advertising coupon remains visible on the package.
Solution Approach 2:
The coupon is pre-positioned at the rear of the inner package rather than the front, so that it does not initially obstruct the pull-off portion. This preliminary placement decision eliminates the need for users to spend time removing a front-positioned coupon before accessing cigarettes.
3Ease of operation
If the coupon is positioned to not obstruct the pull-off portion, then access to cigarettes is easy, but the coupon may not be as visible or accessible
Solution Approach 1:
The coupon is repositioned from the traditional front horizontal placement to the rear vertical placement on the inner package. This dimensional change allows the coupon to remain visible and accessible while eliminating obstruction of the pull-off portion, as it is now positioned where it cannot interfere with the opening mechanism.
Solution Approach 2:
Instead of placing the coupon at the front where it is most visible but obstructive, the coupon is inverted to the rear position where it is equally visible when the package is held normally, but no longer creates harmful obstruction. The advertising function is preserved while the harmful effect is eliminated.
