Universal Solvent
Wednesday, August 26, 2009 7:34 PM
Situation Analysis
Once Edison asked a young man, who wanted to work for him, what he would like to invent the most. "I would like to invent the solvent, which dissolves everything"-responded the young man. "Good idea"-said Edison, "and where are you going to store your miracle?"
Where would you store this miracle?
-
1. Task
We need to find a way to store a universal solvent.
2. System
Ways to store a universal solvent
3. Main function: To be able to store a universal solvent
Additional function: To be able to store other stuff as well
4. MUST: Keep universal solvent intect while storing solvent
Desirable: Preserve it for long periods
5. Super system
Storing
6. Improvements to storing
Ways to store this universal solvent are needed
7. Can improvements to storing be done without modifying the ways to store the universal solvent?
Yes. You can change the universal solvent in some way.
8. Human factors? - No
9. -
10. Main aim for improving situation
Universal solvent can be stored.
11. Formulation of tasks
Think of ways to prevent universal solvent from dissolving its container.

Su-field Analysis
The reaction between the solvent and the container can be represented by this model:
-
Rule 1: not applicable as the solvent should not be replaced.
-
Rule 2:
| Fields | Substance used |
| Mechanical | Perform centrifugation on the solvent |
| Acoustic | Add acoustic currents to suspend the liquid |
| Thermal | Freeze to a solid/boil and obtain the gaseous state |
| Chemical | Add a chemical which can be removed to temporarily stop the dissolving of the solvent |
| Electric | Use electric currents to separate the solvent into two different liquids |
| Magnetic | Input the liquid in between two strong repelling magnets |
| Biological | Add non-competitive inhibitors which can be removed to stop the catalysis of reaction |
| Intermolecular | Expose it to radiation to temporarily stop the properties of the solvent |
Rule 3:
| Fields | Substance used |
| Mechanical | Put it into a container with strong centrifugal force |
| Acoustic | Add acoustic waves to the wall of the container |
| Thermal | Cover the inner wall of the container with a device which emits thermal energy to heat/cool the solvent |
| Chemical | Coat the container with a chemical to stop the reaction of the solvent temporarily |
| Electric | Strong electrostatic currents on the inner wall surface of the container to prevent the liquid from touching the wall |
| Magnetic | Charge the solvent with a magnetic field opposing the magnetic field of the walls of the container |
| Biological | Cover the wall with a large amount of bacteria |
| Intermolecular | Add radioactive chemicals in the wall of the container |
Rule 4:
| Fields | Substance used |
| Mechanical | Install a spinner which spins the liquid at a high speed |
| Acoustic | Charge acoustic waves to the surface of the container wall to suspend the solvent |
| Thermal | Heat the container to a high temperature or cool it to a low temperature |
| Chemical | Coat the container with a layer of chemical to stop the reaction of the solvent temporarily |
| Electric | Install wires and electric circuits on the inner container wall |
| Magnetic | Coat a strong layer of magnet which has the same magnetic poles as the solvent to repel it from the wall |
| Biological | Cover the wall with a large amount of bacteria |
| Intermolecular | Add a layer of radioactive chemicals around the wall of the container |
Rule 5:
Not applicable as the solvent cannot be exerting another field by itself.

IUR
- I wish the container can store the solvent without itself being dissolved.
- a) The properties of the solvent
b) It allows the solvent to dissolve anything.
Chemical reaction will occur between the container and the solvent and the solute will be dissolved.
c) It is necessary to:
- Stop the reaction from occurring
d) TT1: To prevent any chemical reaction between the solvent and the container
| Resources | |
| Substance | The container The solvent Air |
| Energy | Sun Wind Chemical potential Energy Electrical energy Kinetic energy |
| Field | Mechanical: Vibration, friction Acoustic: - Thermal: Heating/Cooling Chemical: Reactants, Reaction Electric: Electrical current Magnetic: - Biological: Bacteria, enzymes Intermolecular: Particles |
| Time | Time before adding solvent into container Time when solvent is in container |
| Space | Outside the container Inside the container |

| Question | Resource | Question | Idea |
| CAN | Container | prevent any chemical reaction between the solvent and the container? | 1. Put it into a container with strong centrifugal force 2. Coat the container with a chemical to stop the reaction of the solvent temporarily |
| Solvent | Add a chemical which can be removed to temporarily stop the dissolving of the solvent | ||
| Air | - | ||
| Sun | Prevent exposure to sun which may increase the rate of catalysis | ||
| Wind | - | ||
| Chemical potential energy | Ensure that the internal potential energy of the solvent is high and constant | ||
| Electrical energy | Use electrolysis to separate the solvent into two harmless chemicals | ||
| Kinetic energy | - | ||
| Vibration | Add the spinner so as to reduce the time of contact between the solvent and the container | ||
| Friction | - | ||
| Heating/Cooling | Freeze to a solid/boil and obtain the gaseous state | ||
| Reactants | - | ||
| Reaction | - | ||
| Electrical current | Refer to electrical energy above | ||
| Bacteria | In a large amount, to be dissolved gradually – only for temporary storage | ||
| Enzymes | Add inhibitors to decrease the number of successful products | ||
| Particles | Both the solvent’s and the container’s magnetic field should be similar, so as to allow repulsion to take place. | ||
