Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle wheel systems lack an efficient and secure method for enabling emergency running with a flat tire, as current solutions are either cumbersome or insufficient for ensuring safe and stable operation.
Innovation Solution
A device with a circular or annular base body featuring a positioning device for accurate placement and a fastening mechanism, including clamping elements and a locking mechanism, that can be independently operated to securely attach the device to the vehicle wheel, ensuring centered and firm attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a positioning device and fastening device are used independently, then the attachment can be easily and securely attached to the vehicle wheel, but the device complexity increases
Solution Approach 1:
The attachment device is divided into two independent functional components: a positioning device for centering the attachment on the rim, and a fastening device for securing the attachment. This segmentation allows each component to perform its specific function efficiently without interfering with the other, making the overall attachment process easier while managing complexity through functional separation.
Solution Approach 2:
The positioning device is designed to work independently of the fastening device, allowing the positioning function to be performed without requiring the fastening mechanism to be activated. This multi-functionality enables the system to handle both positioning and fastening operations separately, improving ease of operation while keeping each subsystem relatively simple.
2Reliability
If the fastening device is actuated independently of the positioning device, then the attachment can be firmly fastened to the vehicle wheel, but the manufacturing precision requirements increase
Solution Approach 1:
The positioning device performs the centering and preliminary positioning of the attachment on the rim before the fastening device is activated. This preliminary action ensures that the attachment is correctly positioned in advance, allowing the fastening device to simply secure the already-positioned attachment without requiring high precision during the fastening operation itself.
Solution Approach 2:
The positioning device acts as an intermediary between the attachment and the fastening device. It first establishes the correct positional relationship between the attachment and the rim, then the fastening device secures this pre-established position. This intermediary step separates the positioning and fastening functions, reducing the precision requirements for each individual component.
3Ease of operation
If the positioning device remains unclamped after final attachment, then the fastening device can be actuated independently, but the stability of the attachment decreases
Solution Approach 1:
The positioning function is extracted from the fastening mechanism, allowing the positioning device to remain unclamped and independent after the attachment is secured. This extraction enables the fastening device to be actuated independently without being constrained by the positioning device, while the positioning device continues to provide guidance and centering functionality without interfering with the fastening operation or compromising stability.
