Aerodynamics Improvement TRIZ Cases

A rigid bumper baffle with a controlled partition gap redirects air to the heat exchanger while reducing flapping noise and build complexity.

Aluminum composite panels with a polyethylene core cut vehicle accessory weight while improving impact resistance, aerodynamics, and fuel efficiency.

Bonded composite preforms and molded channels strengthen a liftgate inner panel while cutting steel use, weight, and manufacturing cost.

Cellular sidewall reinforcements stiffen the underbody fairing against lifting loads and lateral impacts while protecting conduits and batteries.

Using aluminum composite material, this case shows how vehicle accessories cut weight while preserving damage resistance, aerodynamics, and appearance.

A rear bumper shield hides the silencer from rear view while guiding underfloor air downward to reduce entrainment and improve aerodynamics.

Molded-in bulkhead ribs reinforce liftgate panels without extra steel or plastic parts, cutting mass, assembly time, and build variation.

Bonded composite reinforcements and structural channels cut liftgate weight while meeting load requirements with less steel and lower tooling cost.

Horizontal and vertical bumper tabs hold and align the rear air deflector panel, cutting assembly time and avoiding misalignment.

Molded-in bulkhead ribs reinforce liftgate panels to meet structural targets without extra steel or plastic parts, weight, or assembly steps.

Widened fastening tab bases screen the bumper skirt-deflector clearance, limiting air infiltration and improving vehicle aerodynamics.

By extracting air from beneath the vehicle, this duct preserves ground-effect downforce and handling even with increased ride height.

L-shaped hooks and openings keep the under-engine protection panel retained during vehicle assembly, reducing drop risk and line disruption.

Real-time drag measurement lets a vehicle platoon adjust spacing and guidance to cut energy use under changing aerodynamic conditions.

An angled rear air guide and uneven flow separation edge cut underbody drag, stabilize airflow, and preserve ground clearance.

A rear fairing kick-out reshapes trailer airflow to cut drag while preserving tire movement clearance under the trailer.

A reusable mechanical measuring device sets the roof-mounted air deflector for different trailer heights, reducing drag and fuel consumption.

A composite spring in the strut assembly resists inward deflection during side impacts, helping preserve trailer side-skirt airflow and reduce wear.

A multi-panel flatbed trailer skirt uses gaps and profiles to redirect airflow, reduce drag, and limit impact damage.

Aerodynamic wheel skirts redirect headwinds away from upper wheel surfaces, reducing drag while preserving axle-level mechanical advantage.

This case uses ramped air channels, an uneven separation edge, and ribs to reduce drag while preserving clearance and rigidity.

An extruded airdam with a J-shaped cross-section and dual-durometer body deflects upon obstacle contact while maintaining aerodynamic profile.

Intermediary support members lock overlapping underbody fairings, resolving vibration noise without increasing vertical bulk.

Flat undertray air inlet with eddy structures directs cool airflow to engine components, resolving packaging space constraints in the engine compartment.
