Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If aerosol sealant dispenser is used for tire repair, then tire puncture can be sealed, but user is exposed to hazardous chemicals and roadside dangers

Engineering Contradiction:

Improvetire repair effectivenessVSAvoiduser exposure to hazardous chemicals

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a valve assembly as an intermediary component between the sealant canister and the tire. This valve assembly includes a valve body with a valve seat and valve stem that controls the release of sealant. The intermediary valve mechanism allows controlled sealant delivery while isolating the user from direct exposure to hazardous chemicals, as the sealant is delivered through a closed system rather than direct aerosol discharge.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the traditional aerosol dispensing mechanism with a valve-controlled delivery system. Instead of using aerosol propellants that discharge chemicals directly onto the user, the system uses a mechanical valve assembly that controls sealant flow through a regulated pathway. This substitution eliminates the harmful aerosol discharge while maintaining the sealant delivery function.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If aerosol sealant dispenser is used for tire repair, then tire puncture can be sealed, but device becomes cumbersome and complex

Engineering Contradiction:

Improvetire repair effectivenessVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into a single integrated valve assembly. The valve body combines the sealant delivery function, pressure control function, and tire inflation function into one component. The valve stem integrates both sealant release control and air valve operation. This merging reduces the number of separate parts and simplifies the overall system structure while maintaining repair effectiveness.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The valve assembly serves multiple functions: it controls sealant release, regulates compressed air flow, and provides tire inflation capability. By making the valve assembly multi-functional, the patent eliminates the need for separate control mechanisms for each function, thereby reducing device complexity while maintaining reliable tire repair and inflation capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If manual handling of sealant is required, then sealant can be applied to tire, but user safety is compromised during roadside repair

Engineering Contradiction:

Improvesealant applicationVSAvoiduser safety exposure

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The valve assembly enables self-service operation where the system automatically controls sealant delivery without requiring manual handling. The user simply activates the valve mechanism, and the system autonomously regulates sealant flow through the valve body and valve stem to the tire puncture site. This eliminates the need for users to manually handle hazardous sealant containers or spray sealant directly, thereby improving safety while maintaining ease of operation.

Inventive Principle:

Principle #25Self-service

AI summary

A tire repair system for inflating or repairing a tire. The tire repair system includes a housing, a compressor to provide compressed air, a sealant delivery system to supply a mix of a tire sealant and the compressed air, and a hose to engage the tire and to deliver the tire sealant and the compressed air to the tire. The sealant delivery system includes an aerosol canister and a compressor-actuated valve assembly to automatically depress a valve stem of the aerosol canister using pressurized air from the compressor.
