Decompression Bottle Bottom Movable Wall Deformation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decompression absorption bottles face challenges in suppressing deformation of the body part during decompression, as the bottom part deforms excessively.
Innovation Solution
The design incorporates a movable wall part with annular recesses and corner configurations that allow for upward deformation, featuring V- or U-shapes, and radial recesses to facilitate easier deformation of the bottom part, reducing body part deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bottom part is made deformable to absorb decompression, then decompression absorption capability is improved, but body part deformation increases
Solution Approach 1:
The bottom part is segmented into multiple functional zones: a ground contact part for stable placement, an upright peripheral wall part for structural support, and an annular movable wall part with recesses for controlled deformation. This segmentation allows each zone to perform its specific function, enabling the bottom part to deform preferentially while protecting the body part
Solution Approach 2:
Different regions of the bottom part are given different mechanical properties. The upright peripheral wall part maintains higher rigidity for support, while the annular movable wall part with V-shaped or U-shaped recesses is designed with lower rigidity to deform easily. This local differentiation of mechanical properties enables controlled deformation behavior that absorbs decompression without transmitting excessive force to the body part
2Stability of the object's composition
If the movable wall part is made rigid for structural support, then structural stability is improved, but decompression absorption capability deteriorates
Solution Approach 1:
The annular movable wall part is designed with V-shaped or U-shaped recesses that enable dynamic deformation behavior. During decompression, these recesses allow the wall part to flex and rotate upward around the connecting portion with the upright peripheral wall part. This dynamic design provides structural stability during normal use while enabling effective decompression absorption when needed

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively suppresses deformation of the body part by allowing preferential deformation of the bottom part during decompression, ensuring reliable and smooth operation.
Implementation Method 1
the movable wall part absorbs the decompression in the bottle by turning upward around a connecting portion with the upright peripheral wall part
Implementation Method 2
the annular recesses have a configuration in which inner corner parts having a V-shape or a U-shape protruding inward in the radial direction of the bottle when viewed from below, and outer corner parts having a V-shape or U-shape protruding outward in the radial direction of the bottle are alternately continued to each other in the circumferential direction of the bottle
