Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bag-in-box systems leave residual liquid in the bag due to inefficient liquid removal, requiring manual squeezing, which is cumbersome and time-consuming.
Innovation Solution
A device with a housing having a vertical orientation, an inclined central section, and a lateral opening for the dosing unit, allowing complete liquid extraction through a dosing unit guided out of the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flat support base is used in a rectangular box, then the bag-in-box can be easily inserted and removed, but liquid cannot be completely removed from the bag
Solution Approach 1:
The support base is transformed from a flat two-dimensional surface to a three-dimensional inclined surface. The inclined support base extends downward from the rear toward the front of the housing, creating a slope that directs liquid toward the dosing unit. This dimensional change enables complete liquid removal while maintaining ease of bag insertion and removal.
2Device complexity
If a flat support base is used, then the device structure is simple, but manual squeezing is required to remove residual liquid
Solution Approach 1:
The support base is transformed from a flat two-dimensional surface to a three-dimensional inclined surface. The inclined support base extends downward from the rear toward the front of the housing, creating a slope that directs liquid toward the dosing unit. This dimensional change enables complete liquid removal while maintaining ease of bag insertion and removal.
3Device complexity
If manual squeezing is required, then the device structure remains simple, but the process is cumbersome and time-consuming
Solution Approach 1:
The support base is transformed from a flat two-dimensional surface to a three-dimensional inclined surface. The inclined support base extends downward from the rear toward the front of the housing, creating a slope that directs liquid toward the dosing unit. This dimensional change enables complete liquid removal while maintaining ease of bag insertion and removal.
4Loss of substance
If the dosing unit is led out through the lateral housing opening, then complete liquid removal is enabled, but the housing geometry becomes more complex
Solution Approach 1:
The support base is divided into distinct functional sections: a rear portion that contacts the bag-in-box, an inclined central section that directs liquid flow, and a front portion that guides liquid to the dosing unit. This segmentation of the support base into functional zones enables complete liquid removal while maintaining manufacturing simplicity.
Solution Approach 2:
The support base is transformed from a flat two-dimensional surface to a three-dimensional inclined surface. The inclined support base extends downward from the rear toward the front of the housing, creating a slope that directs liquid toward the dosing unit. This dimensional change enables complete liquid removal while maintaining ease of bag insertion and removal.
