Adjustable Drink Lid With Pivot Fit and Tamper Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for protecting drinks from tampering and ensuring drink identification are inadequate, as they fail to provide a secure, adjustable, and personalized lid that fits various glass sizes and prevents substances from being added while allowing easy consumption.
Innovation Solution
A two-piece lid with a pivot mechanism, allowing the top half to spin and adjust to fit different sizes, featuring a semi-circular top and circular bottom with a v-shaped cut-out for expansion, a ridge for secure attachment, and indicia for user recognition, which can be securely fastened to the glass or cup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size lid is used, then the lid can securely cover a specific glass size, but it cannot fit different sizes of glasses
Solution Approach 1:
The lid incorporates a flexible ridge with a V-shaped cutout that allows the ridge to dynamically adjust its shape and size to conform to different glass openings. This dynamic flexibility enables the lid to securely adapt to various glass sizes while maintaining a reliable seal through the elastic deformation of the ridge material.
Solution Approach 2:
The lid's ridge structure is designed with variable geometric parameters, specifically the V-shaped cutout configuration, that allows the effective sealing dimension to change. By modifying the ridge's shape parameters through the cutout design, the lid can accommodate different opening sizes while maintaining secure attachment through elastic recovery.
2Object-affected harmful factors
If the lid opening is made small for security, then substances are prevented from being added, but consumption becomes difficult
Solution Approach 1:
The lid is segmented into two functional zones: a peripheral sealing ridge that provides security by covering the glass rim and preventing substance addition, and a central opening area that allows consumption. This segmentation enables the lid to simultaneously provide security through the sealed perimeter while facilitating easy drinking through the strategically positioned opening.
3Ease of manufacture
If a generic lid design is used, then manufacturing is simple, but the lid cannot provide personalized identification
Solution Approach 1:
The lid employs local quality differentiation by incorporating customizable indicia (such as names, symbols, or colors) in specific localized areas of the lid surface, while the bulk of the lid structure remains simple and uniform for easy manufacturing. This allows personalized identification features to be added to specific locations without complicating the overall manufacturing process.
