Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire replacement methods require significant manual labor, expertise, and external tools, making it inconvenient and sometimes impossible for motorists to replace a tire quickly and efficiently, especially in situations where tools or expertise are lacking.
Innovation Solution
An automatic tire replacement apparatus featuring a hydraulic fluid line system with pistons and power rods, connected to a hydraulic fluid reservoir and retainer, which uses hydraulic fluid pressure to lift the vehicle and automatically loosen/tighten lug nuts via a touch-screen controlled power bolt system, eliminating the need for manual tools and labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual tire replacement methods are used, then the process can be performed with simple tools, but significant manual labor and expertise are required
Solution Approach 1:
The patent replaces manual mechanical operations with an automated mechanical system. A power bolt is automatically inserted through the lug nut and engaged with the wheel hub, eliminating the need for manual wrench operation. The system uses a combination of spring-loaded mechanisms and cam actuators to automatically tighten and secure the lug nuts after wheel replacement, substituting complex manual procedures with an automated mechanical sequence.
Solution Approach 2:
The apparatus is designed to be self-operating once activated. The spring-loaded power bolt mechanism automatically engages and secures the wheel without requiring continuous manual intervention. The system performs the entire sequence of wheel removal and replacement automatically, allowing the device to service itself through its own mechanical mechanisms rather than requiring external manual tools.
2Device complexity
If traditional tire replacement tools are used, then the equipment is simple and portable, but multiple separate tools must be carried and assembled
Solution Approach 1:
The patent combines multiple separate tire replacement tools into a single integrated apparatus. The device merges the functions of a jack, wheel holder, power bolt inserter, and lug nut tightener into one unified system. This consolidation eliminates the need to carry and coordinate multiple separate tools, as all functions are integrated within the single apparatus structure.
Solution Approach 2:
The apparatus is designed to perform multiple functions within a single device. It can lift the vehicle, hold the wheel, insert power bolts, and tighten lug nuts - essentially replacing an entire toolset with one multi-functional apparatus. This universal design allows the same device to handle all aspects of tire replacement without requiring additional specialized tools.
3Ease of operation
If manual wheel replacement is performed, then the motorist can control the process, but the motorist must exit the vehicle for extended periods and perform physically demanding tasks
Solution Approach 1:
The patent replaces manual physical operations with an automated mechanical system. The power bolt mechanism automatically inserts and secures the wheel without requiring the operator to manually tighten lug nuts with a wrench. This mechanical automation eliminates the physically demanding aspects of wheel replacement, allowing the motorist to initiate the process from inside the vehicle and then exit immediately after activation.
