Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If solar cells are mounted on external surfaces of wings, then light collection area is maximized, but aerodynamic properties are disturbed and curved structures cannot be accommodated

Engineering Contradiction:
Improvelight collection areaVSAvoidaerodynamic profile
Core Design Contradiction:
Illumination intensityVSShape

Solution Approach 1:

The solar cell array is nested within the internal volume of the wing structure, placing one object (solar cells) inside another (wing). This allows the solar cells to be protected and integrated without disrupting the external aerodynamic shape, resolving the contradiction between maximizing light collection and preserving aerodynamic properties.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The invention transitions from two-dimensional surface mounting to three-dimensional internal integration. By utilizing the internal volume of the wing rather than external surface area, the design accommodates curved structures while maintaining light collection capability through strategic cell orientation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Shape

If solar cells are integrated into internal wing volume, then aerodynamic profile is preserved, but light collection efficiency is reduced

Engineering Contradiction:
Improveaerodynamic profileVSAvoidlight collection efficiency
Core Design Contradiction:
ShapeVSIllumination intensity

Solution Approach 1:

The solar cells are oriented at specific angles within the internal volume to optimize their local exposure to incident light. This local optimization of cell orientation compensates for the reduced overall light collection efficiency, allowing efficient energy capture while maintaining the aerodynamic profile.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention accommodates curved internal surfaces within the wing structure, allowing solar cells to be mounted on curved carriers that follow the wing's internal geometry. This enables effective light collection on non-planar surfaces while preserving the external aerodynamic shape.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Ease of manufacture

If flat solar cell designs are used on curved airfoils, then manufacturing is simplified, but aerodynamic performance is sacrificed

Engineering Contradiction:
Improvesolar cell applicationVSAvoidaerodynamic performance
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The solar cells are nested within the wing structure rather than mounted on the external curved surface. This allows the use of standard flat or slightly curved solar cells in carriers that are themselves integrated into the wing's internal volume, simplifying manufacturing while preserving aerodynamic performance.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

A carrier structure serves as an intermediary between the solar cells and the wing structure. This carrier can be shaped to optimize both solar cell mounting and aerodynamic performance, acting as a buffer that simplifies the integration process while maintaining performance requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Various aspect provide for a solar assembly. The solar assembly may be a mechanical structure that allows many small solar cells to be integrated into the wing design of an aircraft without placing them on the surface area of the wing or the vehicle. Additional aspects may provide for an adjustable solar assembly. The adjustable solar assembly may be configured to be installed into a structure having a structural profile. When installed, the solar assembly may conform to the structural profile such that the structural profile is maintained. The solar assembly may further comprise an adjustable carrier system comprising a plurality of solar cells attached thereto. The adjustable carrier system may be configured to dynamically adjust the orientation of the solar cells so as to maintain an optimal angle with respect to an external light source.
