Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If exterior lighting devices are added to the vehicle, then the vehicle lighting requirements are met, but the driver's field of view is restricted and the vehicle structure becomes more complex

Engineering Contradiction:
Improveexterior lightingVSAvoiddriver's field of view
Core Design Contradiction:
Illumination intensityVSArea of stationary object

Solution Approach 1:

The lighting device is merged with the aerodynamic component into a single integrated unit. The aerodynamic component serves dual purposes: providing aerodynamic functionality and housing the lighting device, thereby eliminating the need for separate lighting housings that would obstruct the driver's view

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The aerodynamic component is made movable between retracted and extended positions. When retracted, the lighting device remains visible to other road users without obstructing the driver's forward view. This dynamic positioning resolves the contradiction between providing exterior lighting and maintaining driver visibility

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If aerodynamic components are made movable to modify aerodynamic characteristics, then driving characteristics can be optimized, but the supply line reliability and durability become compromised

Engineering Contradiction:
Improveaerodynamic characteristic modificationVSAvoidsupply line reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

A flexible variable supply line is used to connect the movable aerodynamic component to the vehicle body. The flexibility of the supply line allows it to accommodate the movement range of the aerodynamic component without compromising reliability or durability, resolving the contradiction between movability and supply line reliability

Inventive Principle:
Principle #30Flexible shells and thin films

3Volume of moving object

If lighting devices are integrated into the aerodynamic component, then compactness is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvevehicle compactnessVSAvoidmanufacturing complexity
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The aerodynamic component is designed to serve multiple functions: providing aerodynamic performance, housing the lighting device, and acting as a structural mounting element. This multi-functionality reduces the overall number of separate components needed, improving compactness while the modular integration approach keeps manufacturing complexity manageable

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