Solution Overview

Problem

The complexity and cost associated with manufacturing, transporting, and installing separate lids and lock rings for storage containers lead to errors in selection and mating, resulting in issues like leakage or unintended detachment during shipping or handling.

Innovation Solution

A container lid and lock ring combination where the lock ring is configured to extend loosely around the lid and is tightened for securing, with a joint connecting the two, allowing them to be transported, distributed, and installed as a single unit, reducing the need for separate handling and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If lids and lock rings are manufactured and transported as separate items, then manufacturing flexibility is maintained, but device complexity and handling requirements increase

Engineering Contradiction:

Improvemanufacturing flexibilityVSAvoidhandling complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines the lid and lock ring into a single integrated assembly where the lock ring is permanently attached to the lid through integrally formed connection elements. This merging eliminates the need for separate handling, storage, and installation of two distinct components, thereby reducing device complexity and handling requirements while maintaining manufacturing flexibility through modular design

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If lids and lock rings are handled separately, then individual component optimization is possible, but error rate in selection and mating increases

Engineering Contradiction:

Improvecomponent optimizationVSAvoidmating accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

By integrating the lock ring directly to the lid as a single assembly, the patent eliminates mismating errors that occur when separate components are handled independently. The integrated design ensures proper alignment and compatibility, while still allowing for different sizes and configurations of the combined unit to be manufactured for various container types

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The lock ring is pre-attached to the lid during manufacturing, performing the mating action in advance before the assembly reaches the user. This preliminary action ensures correct pairing of components, eliminating the risk of incorrect selection and mating that occurs when components are handled separately

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If two separate parts are used, then functional flexibility is maintained, but quantity of parts and storage requirements increase

Engineering Contradiction:

Improvefunctional flexibilityVSAvoidnumber of parts

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent reduces the quantity of parts by merging the lid and lock ring into a single integrated assembly. This eliminates the need to store, track, and manage two separate components, thereby reducing storage requirements and inventory complexity while maintaining the functional flexibility of the closure system through varied design configurations

Inventive Principle:

Principle #5Merging (Combining)
