Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle designs that improve steering stability often compromise vehicle aesthetics, as fins or other visible structures are used, which affect the design.
Innovation Solution
A vehicle lower structure featuring rectifying members disposed behind the rear tire, composed of first and second rectifying members with specific tilted surfaces and orientations, which rectify wind flow to enhance steering stability without being visibly intrusive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fins are provided on combination lamps or side mirrors to improve steering stability, then steering stability is improved, but the vehicle design is affected
Solution Approach 1:
The patent moves the rectifying members from visible upper portions (combination lamps, side mirrors) to the lower surface of the vehicle body, changing the spatial dimension where the stability-improving structure is located. This dimensional relocation makes the structure invisible from above while maintaining its aerodynamic function.
Solution Approach 2:
The patent extracts the rectifying function from visible vehicle components (combination lamps, side mirrors) and relocates it to the lower surface of the vehicle body. This separation removes the visual impact from the vehicle's aesthetic design while preserving the steering stability benefit.
2Reliability
If fins are provided on side visors to improve steering stability, then steering stability is improved, but the influence on vehicle design increases
Solution Approach 1:
The patent relocates the rectifying members from the upper side mirror area to the lower surface of the vehicle body, utilizing the vertical dimension to hide the structure from view while maintaining its aerodynamic function for improving steering stability.
Solution Approach 2:
The patent extracts the stability-improving fin structure from the visible side mirror region and places it on the lower vehicle surface, separating the functional requirement from the aesthetic constraint.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves steering stability by reducing wind turbulence and maintaining vehicle design aesthetics by positioning rectifying members on the lower surface, ensuring stable straight travel and responsive turning.
Implementation Method 1
wind from the outer side in the width direction of the rear tire and wind from the inner side in the width direction of the rear tire are rectified by the rectifying members disposed behind the rear tire

AI summary
The vehicle lower structure includes a plurality of rectifying members disposed on the lower surface of the vehicle body behind the rear tire. Each of the plurality of rectifying members has a flat plate shape, and protrudes downward from the lower surface of the vehicle body and extends in the vehicle front-rear direction. The plurality of rectifying members is arranged at intervals in the vehicle width direction.
