Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bidet systems face difficulties in effectively spraying sterilizing water throughout the inner walls of toilets due to fixed nozzles and low water pressure, leading to inadequate cleaning and sanitation issues.
Innovation Solution
A sterilized water spraying device with a rotating and linearly movable nozzle unit, powered by a driving unit and gear transmission system, which includes a tubular nozzle with spray holes and a screw thread mechanism for precise positioning and thorough coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed cleaning nozzle is used to spray sterilizing water, then the device structure is simple, but it is difficult to spray sterilizing water throughout the entire toilet interior and achieve proper cleaning
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed nozzle into a movable and rotatable nozzle. The nozzle unit is equipped with a driving unit that enables it to move linearly along the inner wall and rotate around its axis, allowing the spray direction to dynamically adjust and cover the entire toilet interior surface, thereby resolving the contradiction between simple structure and comprehensive cleaning coverage.
Solution Approach 2:
The patent implements another dimension principle by adding rotational movement to the linearly moving nozzle. The nozzle not only moves forward along the inner wall but also rotates around its own axis, creating a two-dimensional motion pattern that enables comprehensive coverage of the toilet interior surface from multiple angles, effectively solving the limited coverage problem of fixed nozzles.
2Use of energy by moving object
If water pressure is kept relatively low, then energy consumption is reduced, but it becomes difficult to spray sterilizing water to the correct position for effective cleaning
Solution Approach 1:
The patent uses dynamics principle to compensate for low water pressure effects. By enabling the nozzle to rotate and move precisely along the inner wall, the system ensures that even low-pressure spray reaches the correct positions systematically, maintaining cleaning effectiveness while consuming less energy compared to high-pressure fixed spray systems.
Solution Approach 2:
The patent applies continuity principle by ensuring the nozzle continuously moves and sprays along the entire inner wall surface without interruption. This continuous action at low pressure achieves thorough coverage and proper positioning, replacing the need for high-pressure intermittent spraying and reducing overall energy consumption while maintaining cleaning precision.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device ensures even distribution of sterilizing water throughout the toilet interior, enhancing sanitation by allowing the nozzle to rotate and move linearly, ensuring effective cleaning and sterilization of the inner walls.
Implementation Method 1
a first gear configured to be coupled to the driving unit and rotate, and a gear cylinder disposed to engage with the first gear and to rotate by rotation of the first gear
Implementation Method 2
the nozzle unit is configured in such a manner that the one end of the nozzle unit provided with the spray holes passes through the second gear, to protrude outwardly of the housing... the nozzle unit rotates together with the gear cylinder as the gear cylinder rotates, and simultaneously, moves linearly as the screw thread is screwed into the thread groove
