Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Beverage container lids often get lost or detached from their containers, leading to inconvenience and waste.

Innovation Solution

A leash system comprising an anchor coupled to the lid and a detachable leash that wraps around the container's handle, with a top aperture attaching to an anchor tab and a bottom slot for secure attachment, preventing lid loss.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a leash system is added to tether the lid to the container, then lid retention is improved, but device complexity increases

Engineering Contradiction:

Improvelid retentionVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The leash system is divided into separate functional components: an anchor attached to the lid, a flexible leash body, and attachment points on the container. This segmentation allows each component to perform its specific function while keeping the overall system relatively simple and easy to manufacture.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The leash acts as an intermediary element between the lid and the container, providing a flexible connection that prevents lid loss without requiring direct attachment mechanisms between the lid and container. This mediator approach simplifies the overall design by using a dedicated connecting component.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the leash uses detachable coupling mechanisms, then ease of operation is improved, but reliability of attachment decreases

Engineering Contradiction:

Improveleash attachment/removalVSAvoidattachment security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The leash system transitions from static permanent attachment to dynamic detachable coupling. The anchor tab and aperture provide a secure connection during use, while allowing easy detachment when needed. This dynamic approach enables the system to adapt between secured and removed states based on user needs.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Instead of requiring complex locking mechanisms to prevent detachment, the design uses a simple aperture-tab configuration where the leash passes through the aperture and secures to the tab. The security comes from the geometry of the tab fitting into the aperture, while removal is achieved by simply pulling the leash away, inverting the typical approach of complex fastening.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

The leash system for use with a beverage container lid includes an anchor and a leash. The leash system for use with a beverage container lid may be used to tether a lid to a beverage container. The anchor may be coupled to the lid. The leash may detachably couple to the beverage container. An aperture located at a top end of the leash may detachably couple to an anchor tab on the anchor to prevent loss of the lid. A bottom end of the leash may detachably couple to a handle of the beverage container by virtue of the leash wrapping around the handle and passing through a slot located at the bottom end of the leash.
