Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional devices use complex connecting mechanisms with valves and mechanical devices to connect the compressor to the container, then the container can be charged with pressure to pump tire sealant, but the device complexity and ease of operation deteriorate significantly
Solution Approach 1:
The device is divided into functionally independent modules: a simple closure element that connects to the container, a separate compressor connection system, and an automated pressure-sensitive opening mechanism. This segmentation allows each component to perform its function independently, reducing overall system complexity while maintaining reliability.
Solution Approach 2:
The closure element incorporates an automated pressure-sensitive opening mechanism that automatically opens the sealant discharge path when a predetermined pressure is reached. This self-service feature eliminates the need for complex manual control systems, multiple valves, and mechanical switching devices, thereby reducing device complexity while ensuring reliable pressure charging and sealant discharge.
2Stress or pressure
If conventional devices require multiple valves and mechanical devices for connection, then pressure control is achieved, but the ease of operation and installation deteriorate
Solution Approach 1:
The invention extracts and eliminates unnecessary intermediate components (multiple valves, complex mechanical switching devices) from the conventional system. The pressure control function is achieved through a simplified mechanism where the pressure-sensitive opening mechanism directly responds to pressure changes, removing the need for complex valve assemblies and improving ease of operation and installation.
Solution Approach 2:
The system uses pressure as a direct control parameter that automatically triggers the opening of the sealant discharge path. By changing from a complex multi-valve control system to a direct pressure-sensitive opening mechanism, the system achieves effective pressure control with significantly improved ease of operation and installation.
3Reliability
If conventional puncture kits include complex connecting mechanisms and multiple components, then complete functionality is achieved, but the weight and production cost increase
Solution Approach 1:
The invention merges the closure element, pressure sensing function, and sealant discharge control into a single integrated component. This consolidation eliminates the need for separate valves, mechanical devices, and control mechanisms found in conventional puncture kits, significantly reducing weight while maintaining complete puncture repair functionality.
Solution Approach 2:
The closure element serves multiple functions simultaneously: it seals the container, senses pressure changes, controls the opening of the discharge path, and connects to the compressor. This multi-functionality eliminates the need for multiple separate components, reducing both weight and production cost while ensuring reliable puncture repair functionality.
4Reliability
If conventional devices require complex connecting operations and precise handling, then complete connection is achieved, but the ease of operation and user-friendliness deteriorate
Solution Approach 1:
The closure element is pre-configured with the pressure-sensitive opening mechanism and sealing components in the correct positions. This preliminary preparation ensures that when the user connects the device to the container and compressor, the system automatically functions as intended without requiring the user to perform complex connecting operations or precise handling, thereby improving ease of operation while maintaining connection reliability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simple, cost-effective, and precise discharge of tire sealant into a tire without complex operations, reducing weight and production costs, and ensuring reliable operation without the need for additional support or vertical orientation.
Implementation Method 1
when a positive pressure is produced in the container, a removal opening can be released in order to discharge tire sealant from the container into a tire
Implementation Method 2
via the connecting tube of short design the device or the closure element with the container hangs on the tire or on the valve of the tire and, because of gravity, automatically always hangs downward
