Solution Overview

Problem

Conventional sun protection devices with solar panels face issues in transitioning between operating and rest positions, leading to exposure and damage of textile materials, restricted functionality, and inflexible folding due to rigid solar panels.

Innovation Solution

Designing support elements and solar panels to form an essentially closed jacket in the folded rest position, utilizing radial spokes as solar collectors that integrate seamlessly with conventional textile fabrics, allowing for flexible folding and operation without affecting the sunshade's functionality, and incorporating a clamping device for optimal tensioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If solar panels are mounted on the upper side of the shade or integrated into support elements, then solar energy can be absorbed and utilized, but the device cannot be moved back and forth between operating and resting positions, leading to fabric damage and operational restriction

Engineering Contradiction:
Improvesolar energy absorptionVSAvoidmovement between positions
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The support elements are designed with articulated joints that allow them to dynamically change configuration between extended and retracted states. The solar panels are mounted on these movable support elements, enabling them to follow the shade through its range of motion without restriction

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

In the retracted position, the support elements with integrated solar panels fold nested within the central shaft assembly. This nesting allows the solar-equipped support structure to compact into a small volume, preventing fabric damage while maintaining solar energy absorption capability when deployed

Inventive Principle:
Principle #7Nested doll (Nesting)

2Use of energy by moving object

If solar panels are rigidly mounted on the shade structure, then solar energy collection is maximized, but the folding mechanism is affected and the parasol cannot be properly folded

Engineering Contradiction:
Improvesolar energy collectionVSAvoidfolding capability
Core Design Contradiction:
Use of energy by moving objectVSShape

Solution Approach 1:

The support structure is divided into multiple segmented sections with articulated joints between them. Each segment can independently fold relative to adjacent segments, allowing the rigid solar panels mounted on each segment to maintain their structural integrity while enabling the overall structure to fold compactly

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support elements incorporate movable joints and hinges that allow the structure to transition between rigid extended configurations for solar energy collection and flexible folded configurations for storage, dynamically adapting to operational requirements

Inventive Principle:
Principle #15Dynamics

3Use of energy by moving object

If the sunshade is permanently tensioned to accommodate solar panels on top, then solar panels can be mounted, but the fabric cannot wrinkle properly during folding and operational flexibility is restricted

Engineering Contradiction:
Improvesolar panel mountingVSAvoidoperational flexibility
Core Design Contradiction:
Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The tensioning system is designed with adjustable components that can dynamically modify fabric tension based on the operational state. During folding operations, the tension is relaxed to allow natural fabric wrinkling and movement, while in the extended operational state, tension is increased to maintain fabric tautness for optimal solar panel positioning

Inventive Principle:
Principle #15Dynamics
