Solution Overview

Problem

Traditional cup carriers are often bulky, expensive, and inefficiently designed, frequently having more cup-engaging portions than drinks provided, leading to unused spaces and suboptimal use of materials.

Innovation Solution

The development of flexible sheet-formed cup carriers with connectable base and handle portions, featuring cup-holding apertures and fasteners, allowing for customizable configurations and efficient use of material, with options for recyclable, biodegradable, or marine-degradable materials, and the ability to be 3D printed or molded for reduced waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional rigid cardboard or formed board trays with four three-dimensional cup holders are used, then cup carriers provide structural strength and stability, but they become bulky, expensive, and inefficiently designed with unused spaces when fewer drinks are provided

Engineering Contradiction:
Improvestructural strengthVSAvoidbulkiness
Core Design Contradiction:
StrengthVSVolume of moving object

Solution Approach 1:

The patent replaces traditional rigid cardboard or formed board trays with flexible plastic sheets containing cup-engaging portions. This flexible sheet approach maintains sufficient structural strength to support cups while dramatically reducing bulkiness and material usage. The thin flexible sheet can be easily stored and transported, eliminating the bulky nature of traditional rigid cup carriers.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The cup carrier is segmented into multiple cup-engaging portions (typically four) that can be independently formed on the flexible sheet. This segmentation allows the carrier to accommodate varying numbers of cups (1-4) efficiently, reducing wasted space when fewer drinks are provided while maintaining structural integrity through the distributed design of the engaging portions.

Inventive Principle:
Principle #1Segmentation

2Strength

If traditional rigid cardboard or formed board trays with four three-dimensional cup holders are used, then cup carriers provide stable cup support, but they become expensive to manufacture

Engineering Contradiction:
Improvecup support stabilityVSAvoidmanufacturing cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The patent uses flexible plastic sheets instead of expensive rigid cardboard or formed board materials. The flexible sheet can be manufactured through cost-effective processes such as injection molding or extrusion, significantly reducing manufacturing costs while maintaining adequate cup support stability through the design of the cup-engaging portions that taper to fit standard cup shapes.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The cup carrier is designed as a disposable item made from inexpensive flexible plastic material. This approach eliminates the need for expensive durable materials and complex assembly processes, allowing for high-volume production at low cost. The carrier performs its function reliably for single use and is then discarded, optimizing the balance between manufacturing cost and functional performance.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Weight of moving object

If plastic sheets with four or six cup-engaging portions are used, then cup carriers can be made from lighter material, but one or more cup-engaging portions often remain empty when fewer drinks are provided

Engineering Contradiction:
ImprovelightnessVSAvoidmaterial waste
Core Design Contradiction:
Weight of moving objectVSLoss of substance

Solution Approach 1:

The cup carrier is segmented into multiple cup-engaging portions (four or six) on the flexible sheet, allowing selective use based on the number of drinks provided. This segmentation enables the carrier to be lightweight while accommodating variable quantities of cups, reducing material waste by only utilizing the necessary number of engaging portions rather than providing fixed rigid structures for all positions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flexible sheet with multiple cup-engaging portions serves multiple functions: it can accommodate 1-6 cups depending on need, can be manufactured in standardized configurations, and can be easily adapted to different drink quantities. This multi-functionality reduces material waste by avoiding over-provisioning while maintaining lightness through the flexible sheet design.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A cup carrier formed from a flexible sheet of material includes a base portion connected to a handle portion. Each of one or more cup-holding portions formed in the base portion includes a cup-holding aperture. The base portion includes one or more base fasteners that are mated to one or more base fasteners of another cup carrier. The handle portion includes one or more handle fasteners that are mated to one or more handle fasteners of another cup carrier.
