Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional container lids lack sufficient strength and stability, leading to warping or damage during storage and transportation, and often become misaligned or unsecured over time.

Innovation Solution

A container lid design featuring a main body with raised surface features, channels, and connecting bridges that enhance strength and stability, along with guides for securement devices like bungee straps or cords to ensure proper alignment and secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional container lids are used, then the lid can cover the container opening, but the lid lacks sufficient strength and stability, causing warping or damage during storage and transportation

Engineering Contradiction:

Improvelid strengthVSAvoidlid stability

Core Design Contradiction:

StrengthVSStability of the object's composition

Solution Approach 1:

The lid is segmented into multiple raised surface features (domes) connected by channels and bridges, creating a modular structure that distributes stress and prevents warping while maintaining overall strength

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The lid combines multiple structural elements (raised features, channels, bridges) into a composite design that leverages the strengths of each component to achieve both strength and stability

Inventive Principle:

Principle #40Composite materials

2Reliability

If conventional container lids are used, then the lid can be attached to the container, but the lid becomes misaligned or unsecured over time during storage and transportation

Engineering Contradiction:

Improvesecuring reliabilityVSAvoidalignment stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The guides are pre-formed on the lid to preliminarily position and align securing devices, ensuring proper alignment is established before the securing process begins, preventing misalignment during storage and transportation

Inventive Principle:

Principle #10Preliminary action

3Reliability

If cords or straps are used to secure the lid, then the lid can be attached to the container, but the securing devices shift or become misaligned or loose over time

Engineering Contradiction:

Improvesecuring reliabilityVSAvoidposition stability

Core Design Contradiction:

ReliabilityVSShape

Solution Approach 1:

The guides serve as an intermediary structure between the lid and securing devices, providing a stable reference framework that prevents the cords or straps from shifting or becoming misaligned during storage and transportation

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A lid for a container includes a main body having interior portion circumscribed by a lip. A plurality of surface features extend from the interior portion. A plurality of connecting bridges are continuous with and interposed between the surface features. Each of the connecting bridges connects at least two of the surface features to each other. A plurality of guides are formed on the lip. The guides are configured to optimally align a securement device across the lid.
