Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle compressor assemblies for tire inflation and sealant application are complex and require multiple stops, leading to increased risk of accidents and traffic jams due to the need for manual operation and energy supply during tire repair.
Innovation Solution
A motor vehicle equipped with a compressor assembly that has a rotationally fixed compression chamber connected to the vehicle wheel, a tire-sealing device with a sealant reservoir, and a pressure fluid source, allowing for automatic sealing and inflation of tires while driving, reducing the need for multiple stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate compressor assembly is used for tire inflation and sealant application, then the tire can be repaired, but the device becomes complex and requires multiple stops
Solution Approach 1:
The patent combines the compressor assembly and sealant reservoir into an integrated tire repair system. The compressor unit includes both a compression chamber for generating pressure fluid and a sealant reservoir for storing sealant, with both components working together through a common delivery mechanism to the tire, eliminating the need for separate devices and reducing operational complexity
Solution Approach 2:
The compressor assembly is designed to perform multiple functions: it can inflate tires using compressed air, apply sealant to seal leaks, and potentially perform both functions simultaneously. This multi-functional design replaces what would traditionally require separate equipment, simplifying the overall system while maintaining comprehensive tire repair capability
2Ease of operation
If the compressor assembly requires manual operation and energy supply during driving, then tire repair can be performed, but the duration of stops increases
Solution Approach 1:
The compressor assembly is designed to be self-contained with its own energy source (battery or capacitor) and control system. Once activated, the system automatically manages the compression and sealant delivery processes without requiring continuous manual intervention, allowing the driver to simply connect the device and resume driving shortly after activation
Solution Approach 2:
The sealant is pre-loaded into the reservoir and the compressor is pre-charged with energy before the tire repair is needed. When a flat tire occurs, the system is already prepared and can immediately begin operation, eliminating setup time and reducing the duration of the stop
3Adaptability or versatility
If the compressor assembly is transported along with the vehicle, then tire repair capability is available, but the device complexity and energy requirements increase
Solution Approach 1:
The sealant is contained in a disposable or replaceable reservoir that can be quickly exchanged when depleted. This approach allows the use of simpler, less expensive sealant containers that don't require complex recycling or refilling mechanisms, reducing overall system complexity and energy requirements while maintaining tire repair capability
Solution Approach 2:
The sealant reservoir is designed as a separate, extractable component from the main compressor assembly. This allows the sealant supply to be independently replaced or refilled without affecting the compressor unit, simplifying maintenance and reducing the energy required for integrated sealant management systems

AI summary
A motor vehicle with a compressor assembly for the supply of a pressure medium to a tire cavity of a tire of a motor vehicle. The compressor assembly has a compression chamber which is rotationally fixed in relation to the motor vehicle wheel, and the compression chamber and the tire cavity are connected via a fluidic connection for the conveying of a pressure medium from the compression chamber into the tire cavity. A tire sealing device has a sealant reservoir with a first connection fluidically connected to a tire cavity of a tire of the motor vehicle to be repaired, and a second connection fluidically connected to a pressure medium source secured to the motor vehicle. The sealant is conveyed out of the pressure medium source into the tire cavity of the tire to be repaired by means of the pressure medium.
