Wheel Rim Blocking Device for Controlled Tire Depressurization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for disassembling two-piece wheel assemblies with tubeless tires fail to safely relieve pressure, leading to potential catastrophic failures and injuries due to the increased strength and stiffness of wheels under higher loads or pressures, especially in industrial applications.
Innovation Solution
A blocking device, such as a safety ring, is introduced that prevents the loosening or removal of assembly nuts until it is removed, which opens a pressure relief channel in the rim to safely depressurize the tire, ensuring the safety of the disassembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the wheel assembly is made stronger and stiffer to carry higher loads or higher inflation pressures, then the load-bearing capacity increases, but the wheel components cannot deflect sufficiently to release trapped air when assembly nuts are removed
Solution Approach 1:
The patent introduces a blocking device that must be removed before disassembly can proceed. This blocking device includes a pressure relief mechanism that automatically depressurizes the tire cavity before the wheel assembly is taken apart, preventing catastrophic failure while allowing the use of stronger, stiffer wheel components
2Ease of operation
If assembly nuts are removed without a blocking device to prevent loosening, then the disassembly process is simpler, but explosive decompression and catastrophic failures may occur
Solution Approach 1:
The blocking device serves as an intermediary component between the assembly nuts and the tire cavity. It includes a blocking member that prevents nut loosening and a pressure relief mechanism that safely depressurizes the system, mediating between the need for simple disassembly and the need to prevent harmful explosive decompression
Solution Approach 2:
The blocking device applies preliminary anti-action by preventing the loosening of assembly nuts until the pressure relief mechanism has safely depressurized the tire cavity. This counteracts the potential harmful effect of explosive decompression before disassembly begins
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
The solution effectively prevents explosive decompression and catastrophic failures by ensuring controlled depressurization, making the disassembly process safer and more reliable, even for stronger and stiffer wheel assemblies.
Implementation Method 1
fastening elements comprising mechanical holding apparatus such as nuts and bolts used to hold together two parts to seal the vessel comprised of the rim and a tubeless tire mounted thereon are provided with a blocking device that prevents loosening and/or removal of said nuts, bolts and/or other mechanical holding apparatus
Implementation Method 2
Removal directly or indirectly causes or requires the opening of a pressure relief channel or channels, which is/are advantageously formed by an air passageway in the rim, allowing, enabling and/or effecting depressurization of the sealed pressure vessel

AI summary
The instant invention is a pressure release safety system for a multi-piece wheel rim and tubeless tire combination, teaching designs for automatically relieving/releasing pressure as part of its disassembly. In this invention, fastening elements used to hold together portions of a wheel rim are provided with a blocking device or devices that prevents loosening and/or removal of fastening elements until said blocking device is first moved from a blocking position, where movement of the blocking device from its blocking position directly or indirectly opens or requires the opening of a pressure relief channel or channels—allowing, enabling and effecting depressurization of the sealed pressure vessel. When applied in the context of a tubeless two-piece wheel/tire assembly, the invention advantageously may include a blocking or safety device (typically in the form of a ring) that covers all or a critical portion of the nuts/studs that hold the two piece wheel together. The act of removing the safety ring so as to access and remove the nuts from the studs to disassemble the wheel, opens an air channel in communication with the tire interior so as to allow pressure to escape from the tire interior.
