Wheel Nut Jig with Temporary Pins for Vehicle Type Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional wheel nut assembly process is time-consuming and prone to errors due to the need for manual identification and selection of correct wheel nuts for various vehicle types moving along an assembly line, leading to increased processing time and potential incorrect coupling.
Innovation Solution
A jig with temporary assembly pins and vehicle class indicators, including color bulbs, that automatically identifies vehicle types and positions corresponding wheel nuts for efficient mounting, reducing the time required for wheel nut assembly and minimizing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If workers manually identify and select wheel nuts for different vehicle types, then wheel nuts can be correctly matched to vehicles, but the processing time increases and error risk increases
Solution Approach 1:
Wheel nuts are pre-sorted and temporarily fitted onto temporary assembly pins according to different vehicle types before the actual assembly process. This preliminary preparation eliminates the need for manual selection during production, reducing both time and error risk.
Solution Approach 2:
Temporary assembly pins serve as intermediaries between different vehicle types and their corresponding wheel nuts. Each pin is designed to accommodate specific wheel nut types, acting as a mechanical selector that ensures correct matching without requiring worker intervention.
2Reliability
If workers manually select wheel nuts for each vehicle type, then correct wheel nuts can be identified, but labor intensity and time consumption increase
Solution Approach 1:
The system segments wheel nuts into different groups based on vehicle types, with each group assigned to specific temporary assembly pins. This segmentation allows for rapid identification and selection without manual intervention, improving both accuracy and speed.
Solution Approach 2:
The temporary assembly pins are designed to automatically indicate which wheel nuts correspond to which vehicle types through visual indicators. The system serves itself by providing self-evident guidance, eliminating the need for worker knowledge and decision-making.
3Ease of operation
If multiple sets of temporary assembly pins are provided for different vehicle types, then wheel nut selection is simplified, but device complexity increases
Solution Approach 1:
The temporary assembly pins are designed with universal functionality where each pin can accommodate specific wheel nut types through standardized interfaces. The pins serve multiple purposes: holding wheel nuts, indicating vehicle type compatibility, and guiding proper installation, thereby reducing overall system complexity.
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 jig automates the identification and selection of wheel nuts, reducing overall processing time and minimizing errors by enabling simultaneous mounting of wheel nuts to vehicles, thus enhancing efficiency and accuracy in the assembly process.
Implementation Method 1
a vehicle class identifying device to identify the kind of vehicle that is moved by a shuttle during a wheel assembly process
Implementation Method 2
The visibility devices are designed to be turned on or off independently of each other depending on the signal from the control unit. Preferably, such visibility devices may comprise color bulbs that are visibly distinguished from each other depending on the kind of vehicle.
