Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional fuel dispensing units use a large number of components for the outer structure, then the structural integrity and functionality are maintained, but the production and assembling costs increase significantly

Engineering Contradiction:
Improveproduction and assembling costsVSAvoidnumber of components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The outer structure is divided into modular components (base module, column module, top module, nozzle module) that can be manufactured separately and assembled vertically. This segmentation reduces the overall complexity by breaking down the complex outer structure into manageable modules while maintaining structural integrity through standardized connection interfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple functional components are merged into integrated modules. For example, the base module combines support functions, the column module integrates structural support and housing, and the top module consolidates various operational components. This merging reduces the total number of separate components while preserving all necessary functionalities.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If traditional horizontal assembly methods are used for fuel dispensing units, then all components can be connected, but complex horizontal connections requiring clean surfaces are needed

Engineering Contradiction:
Improveassembling easeVSAvoidconnection requirements
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The assembly direction is inverted from traditional horizontal assembly to vertical assembly. Modules are stacked one on top of another in the vertical direction, eliminating the need for complex horizontal connections that require clean surfaces. This inversion simplifies the connection requirements while maintaining structural stability.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The assembly approach transitions from two-dimensional horizontal connections to three-dimensional vertical stacking. By utilizing the vertical dimension for module arrangement, the patent eliminates the need for precise horizontal alignment and clean surface connections, thereby simplifying the assembly process and reducing connection complexity.

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

3Reliability

If modules are arranged horizontally in traditional configurations, then space is utilized, but joints between modules are difficult to weather proof

Engineering Contradiction:
Improveweatherproofing capabilityVSAvoidjoint protection complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

By arranging modules vertically instead of horizontally, the joints between modules become horizontally extending interfaces that are easier to weather proof. The vertical stacking allows for overlapping configurations where upper modules can protect joints from environmental exposure, reducing the complexity of joint protection while improving weatherproofing reliability.

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