Pneumatic Tire Outer Mark for Fastener Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large diameter pneumatic tires for construction vehicles require maintenance that involves identifying the installation position of mechanical fasteners on the inner surface, which is challenging due to the tire's size and orientation, making it difficult to perform safe and efficient maintenance.
Innovation Solution
A pneumatic tire with a mechanical fastener member on the inner surface and an outer surface mark indicating the corresponding position, allowing for easier identification of the fastener's location, thereby facilitating safer and more efficient maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical fastener is installed on the inner surface of a large diameter tire, then the fastener can securely hold monitoring devices, but the installation position becomes difficult to identify from the outside
Solution Approach 1:
The patent applies the copying principle by creating an external indicator that replicates the positional information of the internal fastener. The mark on the outer tire surface serves as a copy or representation of the fastener's location on the inner surface, allowing workers to identify the fastener position from the outside without directly observing the interior. This resolves the contradiction by maintaining the fastener's secure holding capability while providing external visibility of its position.
Solution Approach 2:
The patent uses an intermediary approach by introducing a mark or indicator as a mediator between the internal fastener and the external observer. This intermediary element transfers the positional information from the hidden internal fastener to the visible external surface, enabling position identification without compromising the fastener's functional reliability in securing monitoring devices.
2Ease of operation
If the tire is stood up vertically for maintenance, then the tire can be accessed for inspection, but workers cannot safely reach high positions on large diameter tires
Solution Approach 1:
The patent applies preliminary action by providing external marks that indicate fastener positions before the tire is stood up for maintenance. This allows workers to plan their approach and positioning in advance, knowing exactly where to access the fasteners, thereby improving safety by avoiding the need to climb to unsafe heights on large diameter tires.
Solution Approach 2:
The external mark serves as an intermediary that bridges the gap between the worker's external perspective and the internal fastener location. This mediator enables workers to identify and access fasteners safely from ground level or lower positions, eliminating the need to climb to dangerous heights on vertically positioned large diameter tires.
3Measurement precision
If more time is spent locating the fastener on the tire inner surface, then the fastener position can be accurately identified, but maintenance time increases
Solution Approach 1:
The copying principle is applied by creating an external visual copy of the fastener's positional information on the tire's outer surface. This eliminates the need for time-consuming internal inspection to locate the fastener, as the mark provides immediate and accurate position identification from the outside, thereby maintaining measurement precision while dramatically reducing maintenance time.
Solution Approach 2:
The tire structure itself provides the location information through the external mark, eliminating the need for additional tools or complex procedures to locate the fastener. The mark serves as a self-indicating feature that automatically guides workers to the correct position, improving both accuracy and efficiency without requiring extra time for location determination.
