Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional tire repair kits cause secondary damage to broken tires and are inconvenient to store due to their size and design, leading to increased air loss and incomplete sealing of tire holes.

Innovation Solution

A tire repair kit with a guiding tip end having a decreasing diameter, a connection end, and a receiving space to hold a tire patch, allowing for insertion and expansion without over-damaging the tire hole, and compatibility with various tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional tire repair needle with a branch structure is used to insert a tire patch, then the tire patch can be inserted into the broken hole, but the branch structure causes secondary damage or multiple damages to the broken hole, increasing air loss and preventing complete sealing

Engineering Contradiction:

Improvesealing effectivenessVSAvoidsecondary damage to broken hole

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The tire repair kit is divided into separate components: a needle-less insertion tool for creating the initial opening, and a separate patch application mechanism. This segmentation eliminates the damaging branch structure while maintaining the ability to insert and secure the patch effectively.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The harmful branch structure is completely removed from the design. The patent extracts only the essential function of patch insertion without the damaging elements, using a smooth bore needle-less tool that creates minimal additional damage to the broken hole.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If a conventional tire repair kit with larger size components is used, then the tools are functional for repair, but the kit is inconvenient to carry and store

Engineering Contradiction:

Improveconvenience of storage and carryingVSAvoidstorage space requirement

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The tire patch is nested within the body of the insertion tool during storage. The tool acts as a container for the patch, and both components nest together compactly. This nesting approach dramatically reduces the storage volume while maintaining full functionality of both components.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The insertion tool and patch holder functions are merged into a single integrated device. The tool body simultaneously serves as the insertion mechanism and the storage container for the patch, eliminating the need for separate carrying cases or multiple components.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A tire repair kit has two ends including a guiding tip end having a diameter gradually decreasing to form a tip head and a connection end adapted to connect with a tool and capable of being axially detaching from the tool, wherein a receiving space defined between the guiding tip end and the connection end adapted to hold a tire patch inside.
