Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Water storage tanks face issues with bacterial growth due to prolonged water stagnation, leading to compromised sanitary conditions and microbiological risks, especially when water usage is low.
Innovation Solution
A water storage tank with a control unit that adjusts the full water level based on discharge amount or user selection, utilizing multiple water level sensors and a flow sensor to prevent water stagnation and ensure clean water supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water is stored in a water storage tank for a long period to maintain full level, then water supply reliability is improved, but bacterial growth occurs and sanitary conditions deteriorate
Solution Approach 1:
The patent applies the dynamics principle by making the full water level adjustable rather than fixed. The control unit dynamically changes the full water level height based on water discharge amount or user selection, allowing the system to adapt to different usage conditions. This prevents water from remaining stagnant for prolonged periods, thereby inhibiting bacterial growth while maintaining reliable water supply.
Solution Approach 2:
The patent implements parameter changes by varying the full water level height parameter. The control unit adjusts this parameter based on discharge amount measurements or user inputs, changing the operational state of the water storage tank. This parameter adjustment prevents stagnant water conditions that lead to bacterial proliferation while ensuring adequate water supply.
2Loss of substance
If water discharge amount is low, then water consumption is reduced, but water remains in the tank for a long time causing sanitary issues
Solution Approach 1:
The patent applies feedback by using the control unit to monitor water discharge amount and adjust the full water level height accordingly. When discharge amount is low, the control unit reduces the full water level, preventing excessive water accumulation and stagnation. This feedback mechanism maintains sanitary conditions while allowing reduced water consumption during periods of low usage.
3Stability of the object's composition
If full water level is maintained at a fixed height, then water supply stability is ensured, but water stagnation occurs when usage is low
Solution Approach 1:
The patent transforms the fixed full water level into a dynamic parameter that can be adjusted by the control unit. Based on water discharge amount or user selection, the full water level height changes, preventing water stagnation during low usage periods while maintaining supply stability when needed. This dynamic adjustment resolves the contradiction between stability and stagnation prevention.
