Bottle Bottom Movable Wall Ribs for Decompression Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bottles have limited pressure reduction-absorbing performance due to the design of their movable wall portions, which restricts the effective absorption of decompression within the bottle.
Innovation Solution
The bottle features a movable wall portion with radially disposed ribs, including main and connection recesses, where the depth ratio of the connection recess to the main recess is optimized between 2/9 and 1, allowing for increased upward movement and deformation of the movable wall portion during decompression, enhancing pressure reduction-absorbing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the movable wall portion is designed with conventional depth ratio, then the bottle structure remains simple, but the pressure reduction-absorbing performance is limited
Solution Approach 1:
The movable wall portion is segmented into multiple ribs with distinct main recesses and connection recesses. This segmentation allows each rib to function as an independent pressure absorption unit while collectively providing enhanced overall performance, resolving the contradiction between structural simplicity and pressure reduction capability.
Solution Approach 2:
The invention optimizes the depth ratio parameter (D2/D1) of the connection recess relative to the main recess to fall within 2/9 to 1. This parameter change enables the movable wall portion to achieve optimal deformation characteristics during decompression, significantly improving pressure reduction-absorbing performance without requiring complex additional structures.
2Length of moving object
If the depth ratio D2/D1 is equal to or smaller than 2/9, then the manufacturing process remains simple, but the movable wall portion cannot displace sufficiently during decompression
Solution Approach 1:
By specifying the depth ratio D2/D1 to be greater than 2/9 and equal to or smaller than 1, the invention establishes an optimal parameter range that ensures sufficient upward movement distance of the movable wall portion during decompression while maintaining manufacturability through clear quantitative guidance.
Solution Approach 2:
The optimized depth ratio enables the movable wall portion to dynamically deform and displace upward by significant distances when decompression occurs, allowing the structure to adapt its shape in response to pressure changes while maintaining structural integrity.
3Stability of the object's composition
If the depth ratio D2/D1 is greater than 1, then the connection recess becomes deeper, but the movable wall portion cannot effectively deform in the bottle axis direction
Solution Approach 1:
By limiting the depth ratio D2/D1 to be equal to or smaller than 1, the invention prevents the connection recess from becoming excessively deep, which would restrict the movable wall portion's ability to deform effectively in the bottle axis direction during decompression, thus maintaining both structural stability and pressure reduction performance.

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 configuration significantly improves the pressure reduction-absorbing performance by enabling greater displacement and deformation of the movable wall portion, ensuring effective pressure absorption without deforming the bottle's body, thus enhancing the bottle's decompression handling capabilities.
Implementation Method 1
The movable wall portion turns upward and moves rotationally around a connected portion to the rising circumferential wall portion, thereby absorbing decompression within the bottle

AI summary
A bottle of the invention includes a bottom wall portion (19) of a bottom portion (14) that includes a grounding portion (18) located at an outer circumferential edge, a rising circumferential wall portion (21) that is continuous with the grounding portion (18) from a radial inner side of the bottle, and a movable wall portion (22) that protrudes from an upper end of the rising circumferential wall portion (21). The movable wall portion (22) is disposed to be movable upward around a connected portion (25) to the rising circumferential wall portion (21). A plurality of ribs (26) are radially disposed around a bottle axis (O) on the movable wall portion (22), and the ribs (26) include a main recess (26a) that is recessed upward, and a connection recess (26b). A plurality of the main recesses (26a) are arranged at predetermined intervals in the radial direction of the bottle, and the connection recess (26b) connects main recesses (26a), which are adjacent to each other in the radial direction of the bottle, in the radial direction of the bottle together. A depth ratio D2/D1 that is the ratio of a depth (D2) of the connection recess (26b) to a depth (D1) of each main recess (26a) is greater than 2/9 and equal to or smaller than 1.
