Resin Bottle Hexagonal Depression Pattern for Pressure Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Resin-made bottles experience deformation due to inner pressure build-up, which compromises their aesthetic design and structural integrity, especially when filled with carbonated drinks or exposed to high temperatures.
Innovation Solution
The resin-made bottle features a hexagonal lattice pattern of rhombus-shaped depressions with embossed surfaces in specific band-like regions, accompanied by a rib region with discontinuous ribs, to effectively suppress deformation while maintaining aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a reinforcing rib is provided to suppress bottle shape deformation, then the structural integrity is improved, but the aesthetic effect of ornamentation is lost
Solution Approach 1:
The patent applies local quality by creating depressions with different surface characteristics (embossed vs. non-embossed) in specific locations. The embossed depressions in visible regions provide aesthetic appeal while the non-embossed depressions in less visible regions provide structural reinforcement. This local differentiation allows simultaneous achievement of both aesthetic effect and deformation suppression without requiring traditional reinforcing ribs that would compromise appearance.
2Reliability
If the bottle is filled with carbonated drink or placed under high temperature, then the inner pressure builds up, but the bottle shape deforms
Solution Approach 1:
The patent segments the bottle surface into multiple depression regions that distribute the internal pressure more evenly. Instead of a continuous surface that would deform uniformly under pressure, the segmented depression structure creates multiple localized stress distribution zones. The non-embossed depressions act as pressure relief zones that prevent concentrated stress points, thereby suppressing overall bottle shape deformation under high temperature and carbonated drink conditions.
3Shape
If ornamentation is provided in the bottle to achieve aesthetic design effect, then the visual appeal is improved, but the bottle shape deformation under pressure is not suppressed
Solution Approach 1:
The patent applies local quality by creating depressions with different surface characteristics (embossed vs. non-embossed) in specific locations. The embossed depressions in visible regions provide aesthetic appeal while the non-embossed depressions in less visible regions provide structural reinforcement. This local differentiation allows simultaneous achievement of both aesthetic effect and deformation suppression without requiring traditional reinforcing ribs that would compromise appearance.
4Shape
If a continuous pattern is formed on the bottle body, then the aesthetic effect is improved, but the bottle shape deformation is not effectively suppressed
Solution Approach 1:
The patent segments the bottle surface into multiple depression regions that distribute the internal pressure more evenly. Instead of a continuous surface that would deform uniformly under pressure, the segmented depression structure creates multiple localized stress distribution zones. The non-embossed depressions act as pressure relief zones that prevent concentrated stress points, thereby suppressing overall bottle shape deformation under high temperature and carbonated drink conditions.
