Innovation Solution
A system comprising a robot, a dismount stand, and assemblies that automate the disassembly process, including a pick and place system for securing wheels and tires, a bead-breaker system for separating tires from wheels with lubrication, and a dismount stand for separating the tire from the wheel, all controlled by a controller for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional specialized equipment is used for disassembling tire-wheel assemblies, then the disassembly task can be completed, but the equipment has limited versatility and cannot handle certain types of tire-wheel assemblies
Solution Approach 1:
The robotic system is designed with interchangeable end-effectors and programmable control that enable it to handle multiple types of tire-wheel assemblies. The robot can be equipped with different tools such as bead breakers, tire irons, and impact wrenches depending on the specific disassembly task, making a single system capable of performing various disassembly operations on different tire and wheel configurations.
2Productivity
If manual labor is used for disassembling tire-wheel assemblies, then flexibility is maintained, but the process becomes time-consuming and physically demanding leading to worker fatigue or injury
Solution Approach 1:
The patent replaces manual mechanical operations with an automated robotic system that performs disassembly tasks. The robot executes programmed sequences of operations including breaking beads, separating tires from wheels, and handling components, thereby eliminating the need for manual labor while significantly increasing disassembly speed and consistency.
3Productivity
If automated systems are implemented for disassembling tire-wheel assemblies, then productivity increases and manual labor decreases, but the system complexity and initial investment increase
Solution Approach 1:
The automated disassembly system is divided into modular functional units including a robotic manipulator, bead-breaking mechanism, tire separation device, and control system. Each module performs a specific function and can be independently maintained or replaced. This segmentation reduces overall system complexity by making the system more manageable and easier to program compared to a fully integrated monolithic system.

AI summary
A system for disassembling a tire-wheel assembly includes a dismount stand, a robot, a first assembly, and a second assembly. The robot is disposed adjacent to the dismount stand. The first assembly is configured to detachably connect to the robot and engage the tire-wheel assembly. The first assembly and the robot are configured to retrieve the tire-wheel assembly from an initial location and position the tire-wheel assembly on the dismount stand. The second assembly is detachably coupled to the robot and is configured to disengage a tire of the tire-wheel assembly from a wheel of the tire-wheel assembly.
