Solution Overview

Problem

Existing sun shades do not effectively block ultraviolet radiation and provide adjustable shading, limiting user comfort and convenience, especially when used with outdoor furniture like beach or lounge chairs.

Innovation Solution

A sun shade with an adjustable canopy supported by arcuate stanchions that can be positioned at various angles, allowing for customizable shading and ventilation, featuring a slidable canopy design, a back panel, and internal pockets for personal items, which can be attached to or used independently of chairs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If existing sun shades are used, then basic shading is provided, but they do not effectively block ultraviolet radiation and lack adjustable shading

Engineering Contradiction:

ImproveUV radiation blockingVSAvoidadjustable shading

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The sun shade incorporates adjustable stanchions that can be positioned at different angles and heights, allowing the canopy to be dynamically reconfigured to provide optimal UV protection and shading in various orientations and intensities

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The sun shade is divided into modular components including separate stanchions, canopy sections, and base elements that can be independently adjusted and reconfigured to create customized shading patterns and UV protection zones

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If fixed canopy positioning is used, then structural simplicity is maintained, but user comfort and convenience are limited

Engineering Contradiction:

Improveuser comfortVSAvoidadjustable mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The stanchions are designed with adjustable positioning mechanisms that allow users to easily change the angle and height of the canopy support structures, enabling comfortable reconfiguration without complex assembly or disassembly procedures

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If sun shade is designed as standalone device, then independence is achieved, but versatility when attached to outdoor furniture is reduced

Engineering Contradiction:

Improveattachment capabilityVSAvoiddual configuration system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sun shade base is designed with universal attachment features that enable the device to function both as a standalone unit and as an attachment to outdoor furniture such as beach chairs or lounge chairs, providing versatile usability across different settings

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A sun shade blocks or inhibits ultraviolet radiation emitted by the sun from reaching the head of a user. Positioning of supporting stations of the sun shade relative to a base is adjustable so that shading provided by a canopy of the sun shade can be user selected. Positioning of the canopy along the stanchions may also be adjustable. The sun shade is usable as a stand alone device, or it may be attached to other devices such as beach chairs or lounge chairs.
