Tire Balancing System with Perforated Dispensing Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire-balancing systems face issues with complex processing, premature aging of tire rubber, and safety concerns due to the use of additional materials for maintaining shape and packaging requirements for compensating materials, as well as the risk of damage during impact-based container opening.
Innovation Solution
A tire-balancing system with a container having a sealed cavity for balancing material and a perforation for controlled dispensation, combined with a second portion containing a tire accessory, such as a valve core, to ensure easy and safe application of balancing material within the tire, preventing material loss and incorrect accessory usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If compensating material is shaped into pellets or briquettes to facilitate insertion and distribution, then ease of operation is improved, but device complexity increases due to required processing and auxiliary materials
Solution Approach 1:
The compensating material is divided into many small individual particles rather than large pellets or briquettes. This segmentation allows the material to be easily inserted as a flowable substance and automatically distribute itself throughout the tire interior without requiring complex shaping or breaking processes.
Solution Approach 2:
The invention uses simple, inexpensive packaging (such as a tear-open envelope or bag) that is discarded after single use. The packaging is designed to be easily opened and disposed of, eliminating the need for complex reusable containers or sophisticated dispensing mechanisms.
2Stability of the object's composition
If auxiliary materials are added to maintain shape of compensating material, then shape stability is improved, but reliability deteriorates due to premature aging of tire rubber
Solution Approach 1:
The invention removes auxiliary shape-maintaining materials from the compensating material composition entirely. By using small particles that naturally flow and distribute without requiring binding agents or structural supports, the harmful effect of auxiliary materials on tire rubber aging is eliminated.
Solution Approach 2:
The compensating material consists of homogeneous small particles of uniform size and composition, eliminating the need for complex multi-component formulations with auxiliary materials. This homogeneous structure provides sufficient flowability and distribution characteristics without compromising tire rubber integrity.
3Reliability
If container is made robust to withstand shipment, then reliability is improved, but ease of operation worsens due to difficulty in opening
Solution Approach 1:
The container is designed with a segmented opening mechanism, such as a perforated tear line or scored envelope structure. This allows the container to maintain structural integrity during shipment while providing a clear, easy-to-follow path for opening by applying minimal force in the correct direction.
Solution Approach 2:
The container is pre-prepared with weakened lines, perforations, or tear notches that guide the opening process. These preliminary structural modifications allow the container to be easily opened by simple tearing or pulling actions without requiring complex tools or excessive force, while still providing sufficient protection during transport.
4Ease of operation
If impact method is used to open container, then ease of operation is improved, but reliability deteriorates due to risk of tire damage
Solution Approach 1:
Instead of using impact force to open the container (which risks tire damage), the invention inverts the approach by designing the container to open through gentle tearing or pulling actions. The container structure is intentionally weakened along opening lines so that minimal force applied in the correct direction suffices to open it safely.
Solution Approach 2:
The container is pre-equipped with tear lines, perforations, or scored sections that guide the opening process. These preliminary structural features allow the container to be opened by simple manual manipulation without requiring impact forces, thereby eliminating the risk of tire damage while maintaining ease of operation.

AI summary
A tire-balancing including a tire-balancing material in a first pocket of the system and at least one tire accessory such as a tire-valve core in the second pocket of the system. The first and second pockets are spatially separated from one another with a seal and a line of perforation. The first pocket has a duct dimensioned to release the particles, oriented towards the second container, and sealed from the second container. The methods for fabrication of the tire-balancing system and balancing a tire with the use of such system. Before use, the first pocket is opened by separating the second pocket along the perforation, and placed in a tire let a flow of the particles from inside the first container into the tire through the duct. The tire-valve core is removed from the second container and applied to the wheel.
