Bicycle Tire Installation Tool Using Traveling Inclined Plane
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for mounting a bicycle tire onto its rim, particularly using tire irons, face challenges such as high tension requiring additional tools, slippage issues, and potential damage to the inner tube due to improper levering, making the process impractical and unsafe.
Innovation Solution
A tool employing a traveling inclined plane to lift the tire bead above the rim's edge and a downwardly sloped surface for the bead to slide into place, guided by the rim flange, eliminating the need for levering and reducing slippage, with optional enhancements for ease of use, stability, and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tire irons are used to force the bead into the rim, then the tire can be mounted, but the high tension requires multiple tools and assistants making the process impractical
Solution Approach 1:
The tool is divided into two distinct functional components: an elevating ramp section that lifts the bead, and a downward slope section that guides it into the rim. This segmentation allows each part to perform its specific function efficiently, eliminating the need for multiple separate tire irons and assistants.
Solution Approach 2:
The tool acts as an intermediary device between the bead and the rim, providing a controlled path for the bead to follow. Instead of directly forcing the bead into the rim with multiple irons, the intermediary tool with its specific slope geometry guides the bead smoothly into place, reducing the complexity of the operation.
2Ease of operation
If tire irons are used to leverage the bead, then mounting is achieved, but slippage issues occur reducing reliability
Solution Approach 1:
The tool incorporates curved and rounded surfaces, particularly on the elevating ramp and downward slope sections, which provide better contact with the bead and prevent slippage. The curved geometry allows the tool to conform to the bead's shape, ensuring consistent contact and reliable performance throughout the mounting process.
3Ease of operation
If improper levering is used with tire irons, then the bead can be forced in, but inner tube damage occurs creating harmful effects
Solution Approach 1:
The tool serves as a protective intermediary between the mounting process and the inner tube. By providing a controlled elevating and guiding mechanism, it prevents the need for aggressive levering actions that could puncture or damage the inner tube, thereby eliminating the harmful effects associated with improper tire iron usage.
Solution Approach 2:
The tool converts the potentially harmful force required to mount the bead into a beneficial controlled process. Instead of using forceful levering that risks damage, the elevating ramp and downward slope design channel the necessary force through a safe path that protects the inner tube while still achieving successful bead installation.

AI summary
A tool for completing the mounting of a bicycle tire onto its rim that is superior to those provided by the tools of the prior tire irons. The use of a tool is usually required to complete the job of mounting a bicycle tire to its rim due to the high tension developed in the bead of the tire at that stage. The present invention does not rely on a levering arrangement at all, but instead employs a traveling inclined plane to progressively lift the tire bead to a height above the rim's edge, and a downwardly sloped incline to allow the so lifted bead to then slide down into the rim's interior. The invention utilizes the flange, or rim sidewall, of the wheel rim for both support and guidance as it is impelled forward on the rim by impacts on its trailing surface from an object suitable for the function, such as a hammer. A slot is incorporated into the invention to receive the wheel's flange.
