Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing methods for applying uncured compound laminate to tires are used, then the laminate can be applied to the tire, but expensive and specialized equipment is required
Solution Approach 1:
The patent employs disposable adhesive tapes and simple heating elements instead of expensive, specialized laminating equipment. The adhesive tape is applied directly to the tire surface and then heated to activate bonding, eliminating the need for costly industrial laminators while achieving effective laminate attachment.
Solution Approach 2:
The patent replaces complex mechanical laminating systems with a simplified thermal activation system. Instead of using specialized mechanical pressure and bonding equipment, the invention uses heat from simple heating elements to activate adhesive tapes, substituting a complex mechanical process with a simpler thermal process.
2Productivity
If existing methods for applying laminate to tires are used, then the laminate can be affixed to the tire, but the process is costly and inefficient
Solution Approach 1:
The adhesive tape is pre-applied to the tire surface before the laminate is attached. This preliminary action prepares the bonding interface in advance, so that when the heating element is applied and the adhesive is activated, the laminate can be quickly and efficiently bonded without delays for surface preparation or equipment setup.
Solution Approach 2:
The patent divides the tire surface into multiple sections, with adhesive tapes applied to specific areas where laminates need to be attached. This segmentation allows for targeted, efficient application rather than requiring entire tires to be processed at once, improving productivity by focusing resources only on areas needing modification.

Function Achieved in This Case
This method allows for the cost-effective application of laminates to tires, altering their performance characteristics without the need for expensive equipment, by using heat and pressure to permanently adhere the laminate to the tire.
Implementation Method 1
applying heat sufficient to cure the laminate with the electrical heating element
Implementation Method 2
applying pressure to the laminate using the pneumatic pressure element, to permanently adhere the laminate to the tire

AI summary
A method of applying a laminate to a tire includes pre-treating a portion of the tire and placing the laminate on at least the pre-treated portion of the tire. The method further includes placing an electrical heating element on top of the laminate and placing a pressure element over the electrical heating element and the laminate. The method also includes applying heat and pressure to the laminate using the electrical heating element and the pressure element to permanently adhere the laminate to the tire.
