Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire mounting apparatuses cannot universally accommodate different tire and wheel types due to fixed pressure application, leading to potential damage such as chipping and scratching from mismatched elasticity and hardness properties.
Innovation Solution
A tire mounting apparatus with a center cone, housing, horizontal and vertical movable bodies, distance adjusting units, a pressure roller, expansion rollers, and a control unit that adjusts pressure and positioning based on tire and wheel properties to ensure proper assembly without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed pressure is applied by conventional tire mounting apparatus, then the structure is simple, but the apparatus cannot accommodate different tire types and causes damage to the tire bead
Solution Approach 1:
The pressure roller is made movable in the vertical direction through a vertical movable body and vertical distance adjusting unit, allowing the pressing position and pressure to be dynamically adjusted according to different tire types and their elasticity characteristics, thereby resolving the contradiction between adaptability and structural simplicity
Solution Approach 2:
The system changes the pressing parameter (vertical position of pressure roller) based on different tire types and their elasticity properties. The control unit adjusts the vertical distance adjusting unit to set appropriate pressing depths for different tire hardness and elasticity, enabling universal application without causing bead damage
2Reliability
If pressure is not adjusted according to tire elasticity, then the operation is simple, but damage such as chip and scratch occurs on the bead of the tire
Solution Approach 1:
The control unit receives input about tire type and elasticity characteristics, then automatically controls the vertical distance adjusting unit to set the appropriate pressing depth. This feedback-based automatic control prevents bead damage while maintaining ease of operation, as the system self-adjusts based on the tire properties
Solution Approach 2:
The system performs preliminary adjustment of the vertical distance adjusting unit based on pre-input tire type information before the actual mounting process begins. This preliminary positioning ensures that the correct pressing depth is set in advance, preventing damage during operation

Function Achieved in This Case
Enables the assembly of various tire and wheel types by adjusting pressure and positioning, preventing damage and allowing for universal use of a single apparatus, thereby ensuring safe and effective mounting.
Implementation Method 1
The pressure roller is disposed on the vertical movable body and presses a sidewall of a tire during assembly of the tire
Implementation Method 2
The expansion rollers are disposed on the horizontal movable body and guide the bead of the tire such that it enters a rim of the wheel during the assembly of the tire

AI summary
An adjustable tire mounting apparatus can be universally used to assemble various types of wheels and tires to each other. The apparatus includes a cone restricting movement of a wheel, a housing rotatable about the cone, a horizontal distance adjusting unit that adjusts a position of a horizontal movable body with respect to the housing in the radial direction, a vertical distance adjusting unit that adjusts a position of a vertical movable body with respect to the horizontal movable body in the vertical direction, a pressure roller disposed on the vertical movable body that presses a sidewall of a tire, expansion rollers that are disposed on the horizontal movable body and guide the bead of the tire to enter a rim of the wheel, and a control unit that controls operation of the horizontal and vertical distance adjusting units, depending on the types of the tire and wheel.
