Solution Overview

Problem

Printing devices with large displays face challenges in shipping and configuration due to display overhang, which increases shipping costs and is incompatible with existing software orientations, making frequent rotational adjustments costly and unnecessary.

Innovation Solution

A rotational mating assembly that allows the display to rotate between landscape and portrait orientations using a base extendably attached to the enclosure, featuring a base and backing structure with aligned keys and brackets for secure attachment and a protrusion that locks into grooves to guide rotation, reducing manufacturing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the display is permanently attached in landscape orientation, then software compatibility is improved, but shipping efficiency deteriorates due to increased overhang

Engineering Contradiction:

Improvesoftware compatibilityVSAvoidshipping volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The display is designed to be rotatable between landscape and portrait orientations using a rotational mating assembly with keys, brackets, and protrusions. This dynamic configuration allows the display to adapt its orientation based on whether it needs to be shipped (portrait, reduced overhang) or used (landscape, software compatibility), resolving the contradiction between fixed orientation requirements and shipping efficiency

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a robust rotational mating assembly is used to allow frequent rotation, then operational flexibility is improved, but manufacturing cost increases

Engineering Contradiction:

Improverotational flexibilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The rotational mating assembly uses simple, inexpensive components including plastic or metal keys, brackets, and protrusions that can be easily manufactured and replaced if needed. Rather than using a complex, expensive robust mechanism designed for frequent rotation, the patent employs a simpler structure that provides sufficient rotational capability for installation and reconfiguration while keeping manufacturing costs low

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The rotational mating assembly is divided into separate components (keys, brackets, protrusions) that can be independently manufactured and assembled. This segmentation allows each component to be optimized for its specific function and manufactured using cost-effective processes, reducing overall manufacturing complexity and cost while maintaining rotational functionality

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If the display overhangs the enclosure, then landscape orientation capability is improved, but shipping cost increases

Engineering Contradiction:

Improveorientation capabilityVSAvoidshipping cost

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The display's orientation is made dynamic rather than fixed, allowing it to be positioned in portrait orientation during shipping to minimize overhang and reduce shipping costs, then rotated to landscape orientation at the destination to enable full orientation capability and software compatibility. The rotational mating assembly enables this dynamic reconfiguration

Inventive Principle:

Principle #15Dynamics

4Reliability

If the rotational mating assembly uses multiple keys and brackets, then attachment security is improved, but device complexity increases

Engineering Contradiction:

Improveattachment securityVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The attachment mechanism is segmented into multiple simple components (keys, brackets, protrusions) that work together to provide secure attachment. Each component has a straightforward function and geometry, making the individual parts simple to manufacture and assemble, while their combined action achieves reliable attachment security

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The keys, brackets, and protrusions are designed to work together as an integrated rotational mating assembly. The brackets on the base receive the keys, while protrusions on the backing engage with corresponding features, combining multiple attachment elements into a unified mechanism that provides both rotational capability and secure attachment without requiring complex individual components

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A rotation base has a base circular structure. A display backing has a backing circular structure. The backing circular structure is rotatably attached to the base circular structure to permit the display backing to rotate between landscape and portrait orientations relative to the rotation base. One of the base and backing circular structures defines a slot. The other of the base and backing circular structures defines a tab rotatably disposed within the slot.
