Folded-back Bottom Wall Container for Liquid Minimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containers with liquid discharging pumps require a dedicated gadget to fold the suction pipe, increasing costs and complexity, while also facing challenges in minimizing residual liquid and ensuring stability when stacked.
Innovation Solution
A container design with a folded-back bottom wall that transforms into two modes, featuring a folding groove and a truncated cone-shaped peripheral wall to allow the bottom wall to be folded back inside the body part, eliminating the need for a dedicated gadget and enhancing stability and liquid removal efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the suction pipe is folded to minimize remaining liquid, then the amount of remaining product is reduced, but a dedicated gadget is required increasing costs
Solution Approach 1:
The bottom wall itself is designed to be foldable and serves the function of directing the suction pipe, eliminating the need for a separate dedicated gadget. The bottom wall's own structural transformation (from protruding to folded-back mode) performs the liquid minimization function that would otherwise require additional equipment.
Solution Approach 2:
The bottom wall is given multiple functions: it serves as both the container's base structure and the mechanism for positioning the suction pipe to minimize remaining liquid. By making the bottom wall foldable, it universally performs both structural support and liquid management roles without requiring separate components.
2Ease of manufacture
If the bottom wall is folded back inside the body part, then costs are reduced and liquid is minimized, but stability when stacked may be compromised
Solution Approach 1:
The bottom wall is designed to dynamically transform between two modes: protruding downwards (providing stable stacking surface) and folded back inside (minimizing liquid and reducing material usage). This dynamic adaptability allows the same structure to serve different functions depending on whether the container is being stacked or used for liquid discharge.
3Strength
If the bottom wall is made strong, then structural integrity is improved, but folding capability may be reduced
Solution Approach 1:
The bottom wall is segmented into different functional zones: a folding groove area that allows bending and transformation, and other areas that maintain structural strength. This segmentation enables the bottom wall to be both foldable (at the groove) and strong (in the main body), resolving the contradiction between flexibility and strength.

AI summary
A container with a folded-back bottom wall, which is very stable in a rest position, has a strong bottom wall, and makes it possible to minimize the amount of remaining liquid while allowing costs to be reduced is provided. The container with a folded-back bottom wall has a bottom wall and a body part and transforms into a first mode in which the bottom wall is made to project downwards from the lower surface of the body part, and into a second mode in which the bottom wall is folded back inside the body part. The boundary portion between the bottom wall and the body part is folded to have an outwardly-convex shape so that a folding groove is circumferentially formed, and the bottom wall is folded back inside the body part at the folding groove.
