Thermal energy harvesting for dispensing system
Among other things, one or more systems and/or techniques for harvesting thermal energy for utilization by a dispensing system are provided herein. The dispensing system may comprise one or more thermal scavenging devices configured to collect thermal energy from a user. For example, a first thermal scavenging device, coupled to a top housing portion of the dispensing system, may collect thermal energy from a palm of a user hand; a second thermal scavenging device, coupled to a bottom housing portion of the dispensing system, may collect thermal energy from a top portion of the user hand; and/or other thermal scavenging devices may be operatively coupled to the dispensing system. In this way, the collected thermal energy is transformed into electrical energy for powering the dispensing system (e.g., powering a current dispense event, stored for a subsequent dispense event, validation of a refill container, detection of a user, etc.).
1. A system for harvesting thermal energy for utilization by a dispensing system, comprising:
a thermal scavenging device configured to:
collect thermal energy from a portion of a human user responsive to the portion of the human user entering a material dispense zone at a first time; and
transform the thermal energy into electrical energy; and
a utilization device configured to:
utilize the electrical energy to cause the dispensing system to dispense material into the material dispense zone, wherein the portion of the human user is removed from the material dispense zone at a second time after the first time.
2. The system of claim 1 , wherein the collecting the thermal energy is performed while the portion of the human user is a distance away from the dispensing system.
3. The system of claim 1 , wherein the thermal scavenging device is configured to collect second thermal energy and transform the second thermal energy into second electrical energy, and the utilization device is configured to store the second electrical energy.
4. The system of claim 3 , wherein the utilization device is configured to store the second electrical energy within at least one of a battery, a capacitor or a super capacitor.
5. The system of claim 1 , wherein the utilization device is configured to:
modify a dispenser nozzle from a first shape to a second shape based upon the portion of the human user entering the material dispense zone at the first time; and
modify the dispenser nozzle from the second shape to the first shape based upon the portion of the human user being removed from the material dispense zone at the second time.
6. The system of claim 1 , wherein the dispensing system is configured to dispense at least one of a liquid material, a powder material or an aerosol material.
7. The system of claim 1 , wherein the dispensing system is configured to dispense at least one of a soap, an anti-bacterial gel, a cleanser, a disinfectant or a lotion.
8. A method for initiating a dispense event of a dispensing system, comprising:
collecting, via a thermal scavenging device of the dispensing system, thermal energy from a portion of a human user responsive to the portion of the human user entering a material dispense zone at a first time; and
initiating the dispense event of the dispensing system by transforming the thermal energy, comprising transferred heat, into electrical energy and using the electrical energy to cause the dispensing system to dispense material, wherein the portion of the human user is removed from the material dispense zone at a second time after the first time.
9. The method of claim 8 , wherein the collecting the thermal energy is performed while the portion of the human user is a distance away from the dispensing system.
10. The method of claim 8 , comprising:
collecting, via the thermal scavenging device, second thermal energy;
transforming the second thermal energy into second electrical energy; and
storing the second electrical energy.
11. The method of claim 10 , wherein the storing comprises storing the second electrical energy within at least one of a battery, a capacitor or a super capacitor.
12. The method of claim 8 , comprising:
collecting, via the thermal scavenging device, second thermal energy;
transforming the second thermal energy into second electrical energy; and
modifying a shape of a dispenser nozzle based upon the second electrical energy.
13. The method of claim 8 , wherein the dispensing system is configured to dispense at least one of a liquid material, a powder material, an aerosol material, a soap, an anti-bacterial gel, a cleanser, a disinfectant or a lotion.
14. A system for harvesting thermal energy for utilization by a dispensing system, comprising:
a thermal scavenging device configured to:
collect thermal energy from a portion of a human user responsive to the portion of the human user entering a material dispense zone at a first time; and
transform the thermal energy into electrical energy; and
a utilization device configured to:
utilize the electrical energy to cause the dispensing system to perform one or more tasks, wherein the portion of the human user is removed from the material dispense zone at a second time after the first time.
15. The system of claim 14 , wherein the collecting the thermal energy is performed while the portion of the human user is a distance away from the dispensing system.
16. The system of claim 14 , wherein the thermal scavenging device is configured to collect second thermal energy and transform the second thermal energy into second electrical energy, and the utilization device is configured to store the second electrical energy.
17. The system of claim 16 , wherein the utilization device is configured to store the second electrical energy within at least one of a battery, a capacitor or a super capacitor.
