Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for hot tapping a water main and connecting a service line are complex and require multiple devices, making the process cumbersome and inefficient.
Innovation Solution
A tapper device that combines a tapping portion and a coupling portion, equipped with a cutter, allows for tapping the water main and connecting a service line without removing the tapper, simplifying the process and acting as a main stop valve after tapping, using fewer devices and potentially less expensive materials than existing solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional hot tapping method is used with separate saddle, valve, and tapping device, then the water main can be tapped and service line connected, but the process becomes complex and requires multiple devices
Solution Approach 1:
The patent combines the saddle, valve, and tapping device into a single integrated tapper assembly. The tapping device includes an outer body that forms both the saddle structure and houses the valve mechanism, eliminating the need for separate components. This merging of functions directly reduces the number of devices required while simplifying the installation process.
Solution Approach 2:
The tapper assembly performs multiple functions within a single device: it provides structural support as a saddle, controls water flow through an integrated valve, and executes the tapping operation with an embedded cutter. This multi-functionality allows one device to replace three separate devices, directly addressing the contradiction between operational simplicity and device complexity.
2Productivity
If traditional method with separate components is used, then each component can be optimized independently, but the overall process becomes more cumbersome and time-consuming
Solution Approach 1:
The cutter is pre-positioned within the integrated tapper assembly during manufacturing, eliminating the need for separate installation steps. The valve is pre-configured within the same structure, allowing immediate operation upon installation. This preliminary preparation of components within the integrated design reduces on-site assembly time and accelerates the overall process.
Solution Approach 2:
By merging the saddle, valve, and cutter into a single pre-assembled unit, the patent eliminates multiple installation steps required when using separate components. The integrated design allows the entire assembly to be installed in one operation, directly improving productivity while reducing the time loss associated with sequential installation of multiple devices.
3Device complexity
If integrated tapper design is used, then the number of devices is reduced and process is simplified, but the tapper must perform multiple functions simultaneously
Solution Approach 1:
The patent embraces multi-functionality as a core design principle, creating a tapper assembly that simultaneously serves as a saddle for structural support, a valve for flow control, and a tapping device for aperture creation. This universal design directly reduces the number of devices required while the modular internal structure maintains adaptability for different installation scenarios.
Solution Approach 2:
While the overall assembly is integrated, the internal components (cutter, valve mechanism, sealing elements) are segmented into distinct functional modules within the single device. This segmentation allows each function to be optimized independently within the integrated structure, resolving the contradiction between device consolidation and functional versatility.
