Sealant Dispenser Pivoting Control Element for Tire Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealant dispensers are not operated effectively, conveniently, and reliably for repairing punctured tires, as they require complex mechanisms and lack efficient control over air and sealant flow.
Innovation Solution
A sealant dispenser with a cap and serving element that uses a pivotally mounted elongated rod to actuate a control element, allowing compressed air to flow into the bottle and force chemical sealant out through a sealant passage to a punctured tire, featuring a compression spring and inner passages in the cap to facilitate efficient sealant delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional sealant dispensers use complex mechanisms for controlling air and sealant flow, then the device can deliver sealant to the tire, but the operation becomes less convenient and less reliable
Solution Approach 1:
The patent extracts the control function from a complex multi-component mechanism and consolidates it into a single serving element that performs multiple functions (opening air passage, opening sealant passage, and controlling flow) through one pivotal motion, thereby improving ease of operation while reducing device complexity
Solution Approach 2:
The serving element is designed as a multi-functional component that simultaneously controls both the air passage and sealant passage, replacing multiple separate control mechanisms with a single universal control element that improves operational convenience
2Reliability
If conventional sealant dispensers lack efficient control over air and sealant flow, then the structure can be simpler, but the sealant delivery becomes less consistent and less reliable
Solution Approach 1:
The control element is pre-positioned to automatically open the air passage first, followed by the sealant passage, ensuring proper sequencing of operations. This preliminary arrangement of control actions ensures reliable and consistent sealant delivery without requiring complex real-time control mechanisms
Solution Approach 2:
The control element acts as an intermediary component that mediates between the serving element (user input) and the passages (air and sealant), providing efficient and reliable flow control through a simple mechanical linkage that translates pivotal motion into passage opening actions
3Reliability
If the control element remains open after use, then the structure is simpler, but the sealant dispenser becomes less reliable for subsequent uses and may leak
Solution Approach 1:
The control element is designed to automatically return to its closed position after the serving element is released, using its own mounting structure and elastic restoring forces to self-close both passages. This self-service mechanism ensures the dispenser is ready for subsequent uses without requiring manual resetting, while maintaining operational convenience through automatic reset functionality
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
Enables effective and reliable inflation and repair of tires by allowing easy operation and efficient control of air and sealant flow, ensuring consistent delivery of the chemical sealant to the tire.
Implementation Method 1
a compression spring (8) fitted into the upper pipe (31)... the compression spring (8) fitted around the elongated rod (7), between the top end (72) of the elongated rod (7) and the step (37) of the lower pipe (36)
Implementation Method 2
the compressed air of the air compressor can flow into the bottle to force the chemical sealant contained in the bottle to flow out of the sealant output connection tube (34) to be delivered to the punctured tire

AI summary
A sealant dispenser is disclosed, which can cooperate with an air compressor for repairing punctured tires. The sealant dispenser generally includes a bottle (2) with a top opening (21) being filled with a chemical sealant (26), a cap (3) capable of covering the top opening of the bottle, a control element (5) that normally closes an air input connection tube (33) and a sealant output connection tube (35) provided at the cap, and a swing element (4). In use, the air input connection tube is connected to an air compressor, and the sealant output connection tube is connected to a punctured tire. The serving element is operated to conduct a semicircle swing to allow the compressed air of the air compressor to flow into the bottle to force the chemical sealant to flow into the interior of the punctured tire for repairing the tire.
