Facial Tissue Box with Adjustable Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic tissue boxes often stop dispensing tissues in a cascade when there are fewer than half left, requiring users to manually retrieve the remaining tissues, which is inconvenient due to the formation of a large gap inside the box.
Innovation Solution
Incorporating folding lines and perforations into the tissue box design allows the box height to be reduced simply and quickly when the tissue amount falls below half, maintaining the overall dimensions and shape, enabling continuous cascade dispensing by folding and reconfiguring the box structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the box height is reduced when tissue remains are low, then cascade dispensing continues, but the structure becomes complicated and manufacturing becomes difficult
Solution Approach 1:
The box transitions from a static structure to a dynamic one by incorporating fold lines that allow the box height to be adjusted. When tissue remains are low, the box can be folded along the predetermined fold lines to reduce its height, maintaining cascade dispensing functionality without requiring a completely separate compact box structure.
Solution Approach 2:
The box is divided into multiple sections by introducing fold lines at specific locations. These fold lines segment the box into upper and lower portions that can be relative folded upon each other, allowing height reduction while keeping the manufacturing process simple and the overall structure manageable.
2Reliability
If the box height is reduced by elevating the bottom surface, then cascade dispensing continues, but the manufacturing procedure becomes cumbersome
Solution Approach 1:
Instead of permanently elevating the bottom surface through complex manufacturing, the invention provides a dynamic adjustment mechanism using fold lines. The box can be transformed from a standard configuration to a compact configuration by simple folding actions, achieving the same functional result with much simpler manufacturing.
Solution Approach 2:
Rather than elevating the bottom surface to reduce height, the invention folds the upper portion of the box downward along fold lines. This inverted approach achieves height reduction by collapsing the box structure rather than building it up, simplifying the manufacturing process.
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 continuous cascade dispensing of tissues until the last sheet is consumed, improving user convenience and simplifying the manufacturing process by maintaining the original box size and shape while allowing height adjustment.
Implementation Method 1
First, flip over the box so that the bottom surface faces upward. The remaining tissues are shifted downward due to their own gravity.

AI summary
A tissue box comprising front and rear surfaces including horizontal fold lines; a left end surface including a horizontal fold line and a vertical perforation line; a right end surface including a horizontal fold line and a vertical perforation line; a top surface including a tissue pull-out-port; a bottom surface including a horizontal perforation line at the center of said bottom surface and vertical perforation lines at either end; lock keys form in said bottom surface so that said left end surface and right end surface can tuck in said lock keys; and said front surface, rear surface, left end surface, right end surface, top surface, and bottom surface all foldably connect to form a rectangular box. By its construction, said tissue box height can be reduced to prevent the termination of the cascade pulling mechanism when the remaining number of tissues in the box becomes half or less.
