Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plumbing systems, particularly recreational vehicle water heaters, face challenges in thoroughly cleaning and flushing out sludge and deposits due to limited access and inefficiencies in existing siphon technologies, leading to fouling and odor issues when left idle for extended periods.
Innovation Solution
A siphon system with a pressurized fluid source, a divider splitting the fluid between a jet port outlet and a tank flush source conduit, a mixing chamber, and a concentric siphon return conduit, which uses kinetic energy to elevate and efficiently remove waste fluid, allowing for intuitive operation without the need for electrical or mechanical power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional siphon system is used to clean water heaters, then the system structure is simple, but it cannot effectively elevate discharge waste fluid to higher water heads and fails to thoroughly remove sludge and deposits
Solution Approach 1:
The siphon system is segmented into distinct functional components: a pressurized fluid source, a divider, a jet port outlet, a tank flush source conduit, a mixing chamber, and a concentric siphon return conduit. This segmentation allows each component to perform its specific function optimally, enabling the system to elevate waste fluid to higher water heads while maintaining manageable complexity through modular design.
Solution Approach 2:
The system employs a nested configuration where the concentric siphon return conduit is positioned within or alongside the tank flush source conduit. This nesting arrangement allows both conduits to occupy shared space efficiently, enabling the siphon to achieve higher water heads without proportionally increasing the overall device footprint or structural complexity.
2Power
If electrical or mechanical power sources are used to pump waste fluid, then the pumping capability is enhanced, but the system complexity and power requirements increase
Solution Approach 1:
The siphon system is designed to be self-priming and self-sustaining. The pressurized fluid source automatically primes the siphon through the jet port outlet, and once initiated, the siphon effect maintains continuous pumping action without requiring external electrical or mechanical power sources. The system uses its own operating fluid to generate the necessary suction and elevation capability.
Solution Approach 2:
The system utilizes hydraulic principles, specifically the siphon effect and pressure differential, to achieve pumping capability. By creating a pressure difference between the fluid source and the discharge point, the system elevates waste fluid to higher water heads using only fluid pressure and gravity, eliminating the need for motors, pumps, or other mechanical power devices.
3Productivity
If the siphon inlet is placed close to the vessel wall for effective cleaning, then cleaning coverage is improved, but the siphon vacuum may cause the inlet to become stuck against the surface
Solution Approach 1:
The system employs a counterbalancing force to offset the siphon vacuum's adhesive effect. The pressurized fluid jet directed at the vessel wall creates a reactive force that pushes the siphon inlet away from the surface, preventing it from becoming stuck. This counterforce allows the inlet to maintain close proximity to the wall for effective cleaning while remaining mobile and controllable.
4Adaptability or versatility
If water heaters are left idle for extended periods, then usage flexibility is improved, but sludge and deposits accumulate leading to fouling and odor issues
Solution Approach 1:
The system performs preliminary cleaning action by effectively removing sludge and deposits during each use cycle. The high-velocity jet port outlet and pressurized flush source conduit prevent deposit accumulation before it can cause fouling or odor problems, enabling water heaters to remain idle for extended periods without degradation in quality or performance.

AI summary
A siphon is adapted for thoroughly cleaning fluid vessels. The siphon is capable of elevating discharge waste fluid through a transfer of kinetic energy provided by a pressurized fluid source, thereby obviating any need for undesirable electrical, chemical, or other mechanical power sources. An inlet couples pressurized fluid to a divider that splits the pressurized fluid between a jet port outlet and a tank flush source conduit. A siphon return conduit is operative to carry waste fluid from the fluid vessel, with the cleaning attachment protruding from the siphon return conduit. By slightly protruding, the cleaning attachment operatively blocks the siphon return conduit from being held by siphon vacuum against a surface of the fluid vessel while developing a beneficial eddy current flow path. A drain conduit is provided, as is a mixing chamber at a junction between the jet port outlet and an outlet from the siphon return conduit.
