Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resin containers face challenges in withstanding shocks and loads applied vertically, leading to potential collapse when stacked, and weight reduction efforts compromise their strength and handling ease.
Innovation Solution
A resin container design featuring a cushioning section at the lower end with elastically deformable grooves that absorb vertical loads, combined with waveform recessed portions for enhanced strength and reduced stress concentration, allowing for weight reduction while maintaining stability and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the thickness of the bottle is reduced for weight reduction, then the weight of the container is decreased, but the strength of the container is reduced making it unable to withstand shocks or load
Solution Approach 1:
The patent introduces a cushioning section with elastic deformation capability that functions as a flexible energy-absorbing element. This section includes a groove that allows the bottle wall to elastically deform and absorb impact energy, enabling thin-walled construction without sacrificing shock resistance. The elastic deformation mechanism compensates for the reduced material thickness, maintaining strength despite weight reduction.
Solution Approach 2:
The patent changes the local structural parameters by introducing a cushioning section with specific geometric features (groove depth, width progression, positioning). These parameter changes create regions of controlled flexibility that absorb impact energy, allowing the overall wall thickness to be reduced while maintaining adequate strength through localized structural optimization rather than uniform thickening.
2Strength
If conventional grooves are added to ensure strength, then the strength of the container is improved, but the weight reduction goal is compromised and aesthetic performance is degraded
Solution Approach 1:
The cushioning section is positioned specifically at the lower end portion of the body section, concentrating the strength-enhancing features only where they are most needed for shock absorption. The groove within the cushioning section has a specific width progression (narrower at top, wider at bottom) that optimizes elastic deformation locally. This localized quality approach provides necessary strength without adding unnecessary material throughout the entire container, preserving weight reduction benefits.
Solution Approach 2:
The groove in the cushioning section is designed with width that progressively increases from top to bottom, creating a three-dimensional structural feature that efficiently absorbs energy through elastic deformation. This dimensional variation in the groove geometry provides enhanced strength and shock absorption capability without requiring additional material or conventional external reinforcements, thus maintaining weight reduction while improving strength.
3Strength
If conventional grooves are added to ensure strength, then the strength of the container is improved, but the aesthetic performance is significantly degraded
Solution Approach 1:
The cushioning section with its groove is positioned at the lower end portion of the body section, confining the visual impact of the strength-enhancing feature to a localized area. This positioning minimizes the aesthetic impact on the overall container appearance while still providing the necessary structural reinforcement. The groove's width progression is designed to be less conspicuous than conventional grooves, balancing strength requirements with aesthetic considerations.
4Strength
If the cushioning section is placed at the lower end portion, then shock absorption is optimized and stability is improved, but the aesthetic impact is increased
Solution Approach 1:
The cushioning section is positioned at the lower end portion of the body section, confining the visual impact of the strength-enhancing feature to a localized area. This positioning minimizes the aesthetic impact on the overall container appearance while still providing the necessary structural reinforcement. The groove's width progression is designed to be less conspicuous than conventional grooves, balancing strength requirements with aesthetic considerations.
