Soft-Liner Bottle Design for Tool-Free Inner Surface Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hard material bottles are inconvenient to clean due to the need for tools and difficulty in accessing inner surfaces for removing dirt deposits.
Innovation Solution
A soft core bottle design featuring a bottle housing made of hard material and a liner made of soft material that deforms under pressure, allowing for easy cleaning by hand without tools, with the liner securely attached to the housing via threads and featuring protruding points for enhanced friction during cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bottle is made of hard material, then the bottle has high strength and durability, but the bottle is difficult to clean and requires cleaning tools
Solution Approach 1:
The bottle is divided into two functional parts: a hard outer housing that provides structural strength and a soft inner liner that enables easy cleaning. The liner can be independently removed and manipulated for cleaning purposes, while the housing maintains its protective function.
Solution Approach 2:
The inner liner is made of soft, flexible material that can be easily deformed and manipulated by hand. This flexibility allows the liner to be squeezed and massaged to remove dirt deposits from the inner wall, providing easy cleaning without requiring additional tools.
2Ease of operation
If a bottle is made of soft material, then the bottle is easy to clean by hand, but the bottle lacks structural strength
Solution Approach 1:
The bottle structure is segmented into a hard housing and a soft liner, allowing each component to fulfill its optimal function. The housing provides strength while the liner provides cleaning ease, eliminating the need to compromise one property for the other.
Solution Approach 2:
The bottle combines hard and soft materials in a composite structure. The hard housing material provides structural integrity and strength, while the soft liner material provides ease of cleaning, creating a composite system that exhibits both properties simultaneously.
3Ease of operation
If the liner is made of soft material, then the liner can deform under pressure for easy cleaning, but the liner may be difficult to securely attach to the housing
Solution Approach 1:
The attachment interface is designed as a separate functional zone with threading features on both the housing and liner. This segmented approach to the connection interface allows the soft liner to be securely fastened to the hard housing through mechanical engagement, ensuring reliable attachment despite material differences.
