A simplified, low-cost bicycle tire pressure cap with a metal case, anti-leak washer, ventilation disc, rubber gasket, floating holder, warning plug, spring, and transparent cover, which uses color-coded visual cues and a durable design to indicate tire pressure status through the exposure of a warning plug, ensuring easy assembly and low failure rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional mechanical structure is used to actuate the float gage stably, then the tire pressure indication is reliable, but the device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent changes the physical parameters of the floating holder, including its weight, volume, and material composition, to achieve stable indication without complex mechanical structures. The floating holder is designed with specific buoyancy characteristics that allow it to respond reliably to pressure changes while maintaining simplicity.
Solution Approach 2:
The patent applies local quality by designing the floating holder with non-uniform density distribution and specific geometric features in critical areas. The holder has a weighted bottom portion for stability and a lighter upper portion for responsive movement, achieving reliable indication through localized structural optimization rather than overall complexity.
2Reliability
If a complex mechanical structure is used for the tire pressure warning cap, then the float gage can be actuated stably, but the manufacturing cost increases
Solution Approach 1:
The patent merges multiple functions into the floating holder component, which simultaneously serves as the pressure-sensing element, the indication mechanism, and the sealing surface. This integration eliminates the need for separate mechanical actuation components, reducing manufacturing complexity and cost while maintaining stable operation.
Solution Approach 2:
The floating holder is designed to self-regulate its position based on pressure changes without requiring external mechanical actuation. The component uses its own buoyancy and weight characteristics to automatically indicate pressure status, eliminating the need for complex external control mechanisms and simplifying manufacturing.
3Loss of information
If traditional tire pressure warning caps are used, then pressure indication is provided, but the failure rate increases after long-term usage
Solution Approach 1:
The patent designs the floating holder and related components as simple, replaceable parts that can be easily manufactured and replaced if needed. The simplicity of the design means that even if components wear over time, they can be quickly replaced without affecting the overall system, effectively managing long-term reliability through ease of replacement rather than extreme durability.
4Ease of manufacture
If a simplified structure is used for the tire pressure cap, then the manufacturing cost decreases, but the assembly ease may be affected
Solution Approach 1:
The patent segments the tire pressure cap into distinct modular components including the floating holder, warning plug, sealing elements, and housing. This segmentation allows each component to be manufactured independently using simple, cost-effective processes while enabling easy assembly by simply connecting the pre-manufactured modules together in sequence.
