Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a tank is used to store water for heating, then water can be heated and stored for later use, but heat loss from the tank increases and thermal efficiency decreases
Solution Approach 1:
The invention extracts the water storage function from the heating system by using a separate water tank that is not directly heated. Only a small amount of water in the heating chamber is heated at a time, while the bulk water remains in the tank at ambient temperature, eliminating continuous heat loss from storing large volumes of heated water.
Solution Approach 2:
The system uses periodic heating action where water is heated only when needed and for short durations. The heating element operates intermittently to heat water in the heating chamber, rather than continuously heating large volumes of water in the tank, thereby reducing total heat loss.
2Power
If a heater with large contact area is used to heat water, then heating capacity increases, but the time required to heat larger volume of water increases
Solution Approach 1:
The heating system is segmented into a small heating chamber with high-power heating element and a separate large water tank. The heating chamber processes small volumes of water rapidly, while the tank stores larger volumes at ambient temperature. This segmentation allows rapid heating of needed water without the time penalty of heating entire tank volumes.
Solution Approach 2:
The system changes the temperature parameter dynamically - maintaining ambient temperature for stored water in the tank and rapidly increasing temperature only for the small volume in the heating chamber when hot water is needed. This parameter change strategy enables fast heating response without proportionally increasing heating time for larger volumes.
3Productivity
If raw water is introduced at high flow rate into the tank, then water supply speed increases, but disturbance occurs due to collision with heated water
Solution Approach 1:
The water system is segmented into separate flow paths: raw water enters the heating chamber through dedicated inlet pipes, gets heated, then discharged through separate outlet pipes. This segmentation prevents direct collision between high-speed raw water and heated water, maintaining flow stability while allowing high supply speeds.
Solution Approach 2:
The heating chamber acts as an intermediary between the raw water supply and the water distribution system. Raw water is heated in this intermediate chamber before being discharged, preventing direct interaction/collision with other water flows and maintaining overall system stability.

AI summary
The present invention relates to an instantaneous water heater corresponding to a water heater for sequentially heating water directly and indirectly to provide hot water while instantaneously heating the water to a required temperature, wherein the instantaneous water heater minimizes heat loss while enabling instantaneous hot water generation by increasing a heat exchange area. The present invention comprises: a body having a water introduction pipe through which raw water is introduced and a water discharge pipe through which hot water is discharged; a coil pipe connected to the water introduction pipe to allow the raw water to be introduced therethrough and having a lower pipeline for discharging the raw water introduced in the body; a heater for indirectly heating the water introduced in the coil pipe primarily and directly heating the water discharged from the body secondarily to generate hot water; and a steam module in which when the hot water is discharged, the steam of the hot water generated by the heater is introduced to discharge the hot water through the water discharge pipe while filling the steam pressure therein, and when the hot water is not discharged, the steam pressure is lowered.
