Modular Tire Mounting Rig With Guide Rails for Multi-Wheel Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire mounting and dismounting devices are designed for specific tire types, requiring separate devices for different vehicles such as scooters, touring motorcycles, and cars, leading to inefficiency and inconvenience.
Innovation Solution
A versatile tire mounting and dismounting device with a base body featuring lockable guide rails, bead breaker elements, and supports adaptable to multiple tire types, including markings for specific tire types and diameters, and adjustable centering rods and supports for precise alignment and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device is designed for a specific type of tire, then it can perform the mounting and dismounting function reliably, but it cannot be used with different types of wheels (scooters, motorcycles, cars)
Solution Approach 1:
The device is divided into modular components: a base body and detachable supports. Each support can be independently attached or removed from the guide rails, allowing the user to configure the device for different wheel types by selecting appropriate supports rather than designing entirely separate devices.
Solution Approach 2:
The base body with guide rails is designed as a universal platform that can accommodate multiple types of supports. The guide rails accept supports with different configurations (e.g., different bead breaker positions, different support geometries) enabling a single base device to serve multiple wheel types including scooters, motorcycles, and cars.
2Reliability
If multiple specialized devices are used for different wheel types, then each device can be optimized for its specific function, but the overall system complexity and number of tools required increases
Solution Approach 1:
Multiple specialized functions are merged into a single device by combining a universal base body with interchangeable supports. Instead of having separate devices for scooters, motorcycles, and cars, the user can attach different supports to the same base body, reducing the total number of devices from three to one.
Solution Approach 2:
The device transitions from a static, fixed-configuration design to a dynamic, reconfigurable system. The supports can be detached and reattached in different configurations, allowing the device to adapt its structure and function based on the specific wheel type being serviced.
3Strength
If the supports are made of hard materials for durability, then they can withstand the forces during assembly, but they may scratch the rim
Solution Approach 1:
The supports exhibit local quality differentiation: the main body can be made of durable materials for structural strength, while the contact surfaces that touch the rim are made of softer materials (rubber coating or softer metal alloy) to prevent scratching. This localized material property change allows the support to simultaneously achieve durability and rim protection.
Solution Approach 2:
The supports utilize composite material construction, combining a strong structural core material with a softer protective outer layer. This could be a metal core with rubber coating or a composite material that provides both structural integrity and rim-friendly contact surfaces, allowing the support to withstand assembly forces without damaging the rim.
