Traction Media Dispensing System With Pneumatic Duct
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traction enhancing systems are ineffective in consistently delivering traction media, such as sand or gravel, to the appropriate location under vehicle tires in winter conditions due to wind interference and clogging issues, and traditional methods like salt dissolution fail to provide immediate traction on icy surfaces.
Innovation Solution
A traction enhancing system featuring a hopper and duct with a baffle that redirects airflow vertically and a valve for controlled delivery of traction media with vertices designed to contact surfaces, ensuring optimal friction enhancement, and a duct with a 90-degree angle bend to prevent moisture accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If natural media such as sand or gravel are dropped from a hopper in the vicinity of a vehicle's tires, then traction enhancement is achieved, but the media cannot be consistently delivered to the appropriate location due to vehicle speed and atmospheric winds
Solution Approach 1:
The patent uses a pneumatic delivery system where air flow generated by the vehicle's movement is channeled through a duct to transport traction media. The duct is positioned to intake air at the front and discharge it at the rear, creating a controlled air stream that carries the media directly to the tire contact patch, overcoming wind interference and ensuring reliable delivery.
Solution Approach 2:
The patent transitions from simple gravitational dropping of media to a three-dimensional air stream delivery system. The duct creates a directed airflow path that transports media through space in a controlled manner, adding the dimension of aerodynamic transport to overcome the limitations of speed and wind.
2Reliability
If air ducts are used to direct traction enhancing media into the air stream, then delivery to the road surface is improved, but the ducts routinely clog as a result of moisture caused clumping
Solution Approach 1:
The patent changes the physical state or properties of the air stream by heating it. The duct system incorporates heating elements or uses the vehicle's engine heat to warm the air stream, which prevents moisture condensation and clumping of the traction media, thereby preventing clogging while maintaining reliable delivery.
Solution Approach 2:
The patent converts the harmful effect of moisture into a beneficial one by using the vehicle's engine heat or exhaust gases to warm the air stream. This transforms the potential problem of moisture-induced clumping into an opportunity to control the thermal environment and prevent clogging.
3Duration of action of stationary object
If salt is used to melt ice, then the road surface is exposed, but salt becomes completely ineffective once fully dissolved and does not address immediate traction needs
Solution Approach 1:
The patent applies preliminary action by delivering traction media to the road surface before the vehicle reaches it. The pneumatic delivery system propels media forward through the air stream so that it is already in position on the road when the vehicle arrives, providing immediate traction enhancement rather than waiting for chemical dissolution.
Solution Approach 2:
The patent uses disposable traction media particles that provide immediate, short-term traction enhancement. These particles are designed to be consumed quickly upon contact with the road surface, providing immediate friction without relying on prolonged chemical action like salt dissolution.
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
The system effectively increases friction between tires and icy surfaces by ensuring vertices of the traction media contact the ground, providing consistent and immediate traction improvement, even in windy conditions, and preventing clogging.
Implementation Method 1
the duct redirects essentially horizontal airflow vertically toward the ground
Implementation Method 2
a baffle located between the front and rear ends that delivers the traction media into air flow entering the front end of the duct
Implementation Method 3
vertices of the traction media contact the ground, providing consistent and immediate traction improvement

AI summary
A traction media is provided that includes a plurality of axes having a distal origin point and proximal point termination surrounded by one or more faces thus forming a body capable of being delivered by hand or traction enhancing system to a lower surface such as the ground to provide an increased coefficient of friction between an upper surface such as a shoe or tire and the lower surface and a relative air movement duct is provided that includes a controlled path of flow through about a 90 degree angle having an intake, discharge and baffle capable of delivering traction media from a hopper/valve assembly by an air flow to a lower surface such as the ground to provide a controlled path of traction media between an upper surface such as a tire and a lower surface such as the ground.
