Solution Overview

Problem

Existing mobile solar power-generating systems require significant manual effort to deploy photovoltaic panels due to their design, which hinders ease of use and efficiency.

Innovation Solution

A solar panel assembly that utilizes gravitational force to assist in the deployment of panels by connecting them through a deployment mechanism, reducing manual effort, where one panel's gravitational force is converted into a deployment force to rotate another panel into position, and includes a buffer member to facilitate smooth rotation and prevent uncontrolled movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If photovoltaic panels are deployed by manual folding out with consecutive upward rotations, then the panels can be positioned for power generation, but significant manual effort is required

Engineering Contradiction:
Improveease of deploymentVSAvoidmanual effort
Core Design Contradiction:
Ease of operationVSForce

Solution Approach 1:

The first solar panel acts as a counterweight to the second solar panel through the deployment mechanism. As the first panel rotates downward under gravity, its weight generates a moment that lifts the second panel upward, reducing the manual force needed to overcome gravity during deployment.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The gravitational force acting on the first solar panel, which would normally cause it to fall uncontrollably, is converted into a useful deployment force. The deployment mechanism captures this gravitational energy and transforms it into the lifting force needed to raise the second panel, turning a potentially harmful uncontrolled motion into a beneficial assisted deployment.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Power

If multiple photovoltaic panels are deployed simultaneously to increase power generation capacity, then the system output increases, but the deployment complexity and manual effort increase proportionally

Engineering Contradiction:
Improvepower generation capacityVSAvoiddeployment complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The deployment mechanism merges the deployment of two solar panels into a single integrated system. The connecting member couples the motion of both panels, allowing them to be deployed simultaneously through one rotational action rather than requiring separate manual operations for each panel.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The deployment mechanism serves multiple functions: it acts as a hinge for rotation, a force transmission system, a gravitational energy converter, and a synchronization device for coordinating the motion of multiple panels. This multi-functionality reduces the need for separate mechanisms for each panel.

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

3Ease of operation

If the deployment mechanism uses the gravitational force of one panel to lift another panel, then manual effort is reduced, but the mechanism requires additional connecting components

Engineering Contradiction:
Improvemanual effort reductionVSAvoidmechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connecting member acts as an intermediary element that transmits the gravitational force from the first solar panel to the second solar panel. This single intermediate component enables the force transfer and coordinated motion without requiring complex multi-component mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system uses the weight of the first solar panel itself to provide the lifting force for the second panel. The panels serve their own deployment needs through their mutual gravitational interaction, eliminating the need for external motors, actuators, or additional power sources.

Inventive Principle:
Principle #25Self-service
