Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional lid is designed in combination with a container having a specific opening size, then the lid can seal the container opening, but the lid cannot be widely applicable to containers having different opening sizes

Engineering Contradiction:

Improveapplicability to different container sizesVSAvoidlid structure design

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lid structure is designed with an elastic annular element that can adapt to different container opening sizes, making a single lid design universally applicable to multiple container sizes. The elastic element deforms to match the contour of different opening perimeters while maintaining sealing effectiveness.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The lid structure utilizes the elastic properties of the annular element to change its dimensional parameters dynamically. When installed, the elastic element deforms from its initial state to conform to the specific container opening size, allowing the same lid to accommodate various opening dimensions without requiring multiple specialized lid designs.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If a lid is attached to the container opening in a threaded manner to prevent items from falling or spilling, then the sealing effect is improved, but significant force is required to separate the lid from the container

Engineering Contradiction:

Improvesealing effectVSAvoiddetachment effort

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The invention extracts the threading mechanism from the lid structure and replaces it with an elastic retention system. The elastic annular element engages with the container opening through friction and elastic deformation rather than threaded engagement, providing sufficient sealing and retention while allowing easy removal by simply pulling the lid away without requiring torque application.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The threaded mechanical connection system is replaced with an elastic deformation-based retention system. Instead of using threads that require rotational torque for attachment and detachment, the elastic annular element uses elastic potential energy and frictional forces to maintain secure attachment while enabling simple pull-off removal.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If a threaded lid is used to secure the container, then the container opening is sealed, but the items contained in the container cannot be released when the lid and container are connected together

Engineering Contradiction:

Improvecontainer sealingVSAvoiditem accessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The lid structure is segmented into a main body and a detachable elastic annular element. The main body contains the beverage preparation elements and can be removed from the container independently, allowing users to access and remove items from the container without needing to detach the entire lid assembly, thus maintaining sealing when connected while enabling easy item retrieval.

Inventive Principle:

Principle #1Segmentation

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

Enables quick detachment and adaptation to different container sizes, enhancing usability and preventing spills or leaks through adjustable sealing and drainage.

Implementation Method 1

an elastic annular element integrally disposed on a peripheral region of the mainbody, wherein the elastic annular element is used for positioning the lid structure on the opening

Methodology Applied

Scientific EffectElasticity: Elasticity

Implementation Method 2

The covering element is deformably disposed on the central connecting portion. When the covering element is deformed to a first shape, the drain holes are covered by the covering element, and when the covering element is deformed to a second shape, the drain holes are connected to an inner space of the container
