Solution Overview

Problem

Cup holders are often of fixed size, leading to issues with accommodating containers of varying shapes and sizes, resulting in spills, damage to surrounding materials, and frustration for users, especially when trying to fit tall or handled items.

Innovation Solution

A cup holder adapter with adjustable binding posts and arcuate arms that can expand to fit different sizes and shapes, secured with a pressure boss and adjustment screw, providing a non-slip surface with a rubber band to prevent spills and damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cup holders are made of fixed size, then manufacturing is simple and cost-effective, but they cannot accommodate containers of varying shapes and sizes

Engineering Contradiction:
Improveaccommodation of varying container shapes and sizesVSAvoidcup holder structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cup holder is divided into a base and multiple adjustable arms that can independently position themselves to accommodate different container shapes and sizes. The arms can be segmented into different lengths and configurations to adapt to various container geometries.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cup holder employs dynamic arms that can adjust their position and angle to match different container shapes. The arms are designed to be movable rather than fixed, allowing the structure to adapt its configuration based on the container being held.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If cup holders are enlarged to fit taller containers, then tall bottles can be accommodated, but surrounding materials may be damaged

Engineering Contradiction:
Improveaccommodation of tall containersVSAvoiddamage to surrounding materials
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The cup holder structure is segmented into a compact base and extendable arms. The arms can be adjusted to reach tall containers without requiring the entire cup holder structure to be enlarged, thus protecting surrounding materials from damage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adjustable arms act as intermediaries between the base and tall containers. These arms can be positioned to make contact with containers at optimal points, distributing forces and preventing damage to both the container and surrounding materials.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If cup holders are made smaller to secure containers, then containers are held more securely, but they become too tight for larger containers

Engineering Contradiction:
Improvecontainer securityVSAvoidaccommodation of different container sizes
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The cup holder employs dynamically adjustable arms that can change their position and applied force based on the container size. For smaller containers, the arms can be positioned closer together to provide secure holding, while for larger containers, the arms can be spread apart to accommodate the increased dimensions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cup holder allows changes in geometric parameters of the arms (position, angle, distance from base) to adapt to different container sizes. This enables the same structure to provide secure holding for small containers while also accommodating larger containers by adjusting the arm configuration.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If fixed-size cup holders are used, then manufacturing is straightforward, but containers may move around and spill contents

Engineering Contradiction:
Improveprevention of spillsVSAvoidcup holder structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cup holder is segmented into multiple adjustable arms that can independently position themselves to make contact with the container at multiple points. This segmentation allows for better distribution of holding forces and more secure container placement, reducing the likelihood of spills.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different parts of the cup holder structure (the arms) can be adjusted to provide localized contact points optimized for specific container shapes and sizes. This local adjustability ensures that each arm can be positioned to provide optimal support and prevent movement that would lead to spills.

Inventive Principle:
Principle #3Local quality
