Solution Overview

Problem

Existing vehicles with solar panel roofs face issues such as bulkiness, increased weight, difficulty in handling, compromised occupant space, poor visibility, and high cost due to complex mechanisms, making them impractical for personal transportation vehicles.

Innovation Solution

A split hybrid design of solar panels with fixed and flexible portions integrated into the vehicle's canopy structure, allowing maximum exposure when needed and minimal exposure when not in use, using lightweight materials and automated folding mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a roof structure with solar panels is added to the vehicle, then solar energy capture is improved, but vehicle weight and bulkiness increase

Engineering Contradiction:
Improvesolar energy captureVSAvoidvehicle weight
Core Design Contradiction:
Use of energy by moving objectVSWeight of moving object

Solution Approach 1:

The solar panel canopy is designed to be movable rather than fixed, allowing it to be positioned in different configurations (extended, retracted, folded) based on operational needs. This dynamic design enables the canopy to capture solar energy when extended while reducing weight and bulkiness when retracted or folded, resolving the contradiction between energy capture and vehicle weight.

Inventive Principle:
Principle #15Dynamics

2Use of energy by moving object

If a fixed solar panel canopy is installed, then solar energy capture is maximized, but vehicle handling and maneuverability deteriorate

Engineering Contradiction:
Improvesolar energy captureVSAvoidvehicle handling
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The canopy is designed with movable components that can be adjusted or repositioned based on operational requirements. When solar energy capture is prioritized, the canopy can be extended; when vehicle handling is prioritized, the canopy can be retracted or folded, thus resolving the contradiction between energy capture and ease of operation.

Inventive Principle:
Principle #15Dynamics

3Use of energy by moving object

If a large solar panel array is installed, then energy generation is improved, but occupant space and visibility are compromised

Engineering Contradiction:
Improveenergy generationVSAvoidoccupant space
Core Design Contradiction:
Use of energy by moving objectVSArea of stationary object

Solution Approach 1:

The solar panel canopy is designed to be movable and adjustable, allowing it to be positioned to maximize solar exposure when energy generation is prioritized, while being retractable or foldable to restore occupant space and visibility when these are prioritized, thus resolving the contradiction between energy generation and occupant space.

Inventive Principle:
Principle #15Dynamics

4Use of energy by moving object

If a complex mechanism is used for solar panel deployment, then solar energy capture efficiency is improved, but device complexity and cost increase

Engineering Contradiction:
Improvesolar energy capture efficiencyVSAvoidmechanism complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The solar panel canopy utilizes self-service mechanisms such as spring-loaded retractable systems or gravity-assisted folding that require minimal external control or power input. These mechanisms automatically deploy or retract the canopy based on simple triggers or environmental conditions, achieving efficient solar energy capture without complex control systems or high costs.

Inventive Principle:
Principle #25Self-service
