Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soft material lids for containers are prone to deformation during movement, leading to incomplete sealing and liquid leakage due to their inability to maintain a tight fit with the container.
Innovation Solution
A cover structure featuring a hard annular portion and a soft sealing section with a folding section that can switch between sealing and unsealing states, using silicone material for the cover body, which includes a concave-convex matching design to ensure airtight engagement with the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lid is made completely of soft materials, then it can be easily deformed to fit the container, but it is easily deformed arbitrarily during movement causing incomplete sealing and liquid leakage
Solution Approach 1:
The lid combines soft sealing material (silicone rubber) with hard structural material (PP, ABS, or PC) to create a composite structure. The soft sealing ring provides adaptability and sealing, while the hard body maintains structural stability and prevents arbitrary deformation during movement, resolving the contradiction between sealing adaptability and sealing reliability.
2Shape
If a lid is made of soft materials, then it can conform to the container shape, but it cannot maintain a tight fit when the container is moved due to collision
Solution Approach 1:
The lid uses composite materials where the soft sealing ring conforms to the container shape while the hard body provides structural stability. This combination allows the lid to maintain both conformability for sealing and structural stability to resist deformation during movement and collision.
3Stability of the object's composition
If a lid is made of hard materials, then it maintains structural stability, but it cannot provide a tight seal with the container
Solution Approach 1:
The lid combines hard structural material (PP, ABS, or PC) with soft sealing material (silicone rubber). The hard body provides structural stability and maintains shape, while the soft sealing ring embedded in the hard body provides conformability and tight sealing, resolving the contradiction between structural stability and sealing reliability.
4Ease of operation
If a lid is made of soft materials, then it can be easily deformed to seal the container, but it is easily deformed during movement causing the lid and container to cannot be completely sealed
Solution Approach 1:
The lid uses composite materials where the soft sealing ring provides ease of sealing through deformation, while the hard body ensures sealing consistency by maintaining structural integrity during movement. The combination allows the lid to be easily sealed initially and maintains consistent sealing under various conditions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cover structure provides a secure, airtight seal that prevents liquid leakage and is resistant to deformation, making it difficult to detach from the container, while being reusable and environmentally friendly.
Implementation Method 1
the folding section is capable of being switched between a sealing state and an unsealing state
Implementation Method 2
the sealing section is elastically arranged around a periphery of an opening of the container, and includes a sealing section made of soft materials and capable of abutting against the annular inner surface

AI summary
A cover structure is disclosed. When an annular sealing portion of a cover body is engaged with a container, a sealing section of the annular sealing portion abuts against an annular inner surface of the container, and then, a folding section of the annular sealing portion is folded to a sealing state, so that part of the folding section abuts against the annular outer surface of the container to form a dual leak-proof sealing structure. The folding section of the annular sealing portion is an annular elastic and full-peripheral tightening structure. Therefore, the sealing between the container and the cover may be strengthened for a good sealing effect, and preventing liquid in the container from being splashed on surrounding articles. When the folding section is in the unsealing state, the cover can be separated from the container, which is convenient to carry and use.
