(STRAP) System of Thermal Regulation and Preference 

Patent Number: PH-1-2019-000448

Patent Title: (STRAP) System of Thermal Regulation and Preference 

Description

A very low-energy consuming device intended to be worn around the wrist (default placement) which is powered by a rechargeable lithium-ion battery to provide soothing waves of alternating pulses of cooling to the patch of the skin.

This device, which is called “STRAP”, harnesses thermoelectric effect to cool down the contacted skin by means of dynamic wave from neutral, to slightly cool, to cool, and up to cold cycles. The STRAP acclimatizes the entire body by means of taking advantage of the body’s pulse points to experience coolness when the temperature within the environment is high. Since the device is worn on the wrist wherein the blood flow is rich, the cool sensation will circulate faster all throughout the body.

Innovative Features and Benefits:

The STRAP works using a semiconductor chilling plate, thermally conductive member, copper alloy-based heat sink, temperature sensors, lithium-ion battery, dehumidification cooling exhaust fan and temperature control bar. It is designed to work for eight (8) hours straight. 

​The following are competitive advantages of STRAP: 

• Low-power consuming device, with rechargeable battery ready; 
• Wearable and compact design; 
• Economically efficient (based on electric bill expenses and energy consumption by kW); 
• Dynamic cooling system (pre-programmed dynamic wave from neutral, to slightly cool, to cool, up to cold cycles); and 
• Quick and instant effect at the moment of wearing (surface temperature difference of the contacted skin is lower relative to the other parts of the body). 

​The thermal relief is experienced by a person using a STRAP anytime and anywhere with just a press of the button.

Business Potential

The existing cooling technologies used by buildings and homes are expensive since they use an incredible amount of energy just by cooling the area. In fact, said cooling technologies utilize about 67% of all major energy consumption. The STRAP’s economic advantage comes into place by means of reducing said statistics, while maintaining individual thermal comfort, through localized cooling of the body’s pulse points

The respective average monthly electricity bill of commercial air conditioning unit, residential air conditioning unit, residential electric fan and the STRAP is Php 8,522.00, Php 2,435.00, Php 487.00, and Php 205.45. On the other hand, the monthly energy consumption in kWh of commercial air conditioning unit, residential air conditioning unit, residential electric fan and the STRAP is 240kWh, 840kWh, 48kWh, and 20.25 kWh, respectively.

​In terms of marketability, the STRAP has a huge consumer potential ranging from commuters to household members, including professionals and office workers. Basically, this device is for everyone who wants to have a personalized thermal preference and cooling comfort.
