Wireless Warm Mug V.2 – Re-Engineered Performance Enhancement

The wireless warm mug was developed jointly by Design HMI LLC and AME Company Limited in 2015 and utility patent filed at the same time. It was successfully brought to life through Kickstarter and mugs were delivered to 1400+ supporters over a 12-month period.

Based on feedback from supporters Design HMI and AME spent the last year on developing design enhancements as well as quality improvements.

1. Double Plastic Wall and Metal Lining for improved heat insulation of mug body.
2. More effective coffee temperature control – 60^oC for 45 minutes.Ultrasonic weld and O Ring Insert on Mug Body Joint Lines to eliminate leakage.
3. USB port for charging smart phone – Android or iPhone in emergency.
4. Wireless Charging Plate – easy battery charging.
5. Type C USB Connection to Charging Plate for wireless battery charging < 30 minutes.
6. 64 GB USB Flash Memory.
7. Liquid temperature indicator.
8. Higher efficiency 3.7V 3500 mAh Battery.
9. Higher efficiency Nano Heater for warming at low power consumption of 6-8W.
10. Improved Lid Design with Upward Facing Drinking Spout for better experience.
11. Improved Lighting Style with even light rim – blue when ON and RED when battery below 25% power capacity.

Requirement:

Self-heating cup to keep coffee / tea warm at 65C for the 45 minute needed to comfortably drink the coffee / tea

Problem:

1. Hot coffee or tea gets cold very quickly in cup requiring frequent refills.
2. Reheating the coffee or tea in cup reduces taste.
3. Reheating not user friendly and cumbersome.
4. Fast cooling (< 15 minutes) limits drinking pleasure in social / office environment.
5. Heating plates require beverage drinker to stay in place.
6. Heating plates make bottom part hot white top drinking area stays lukewarm.
7. Heating plate requires and easy use power outlet – difficult in office or on road.
8. Heating plates hot touch – not kid friendly.

The Wireless Warm Cup uses patented nano heating technology. Conventional heating elements use a metal coil, energy outputs come from a high electrical resistance of the metal coils with low efficiency and high power loss. In our Wireless Warm Cup by adjusting the composition and thickness of the coating layers, the electrical resistance of the coating system can be controlled and conductivity can be increased to generate high efficiency.

 

Layers of a conformal nano thickness heating material that is coated onto a glass surface as the heating element in the base of the cup. The heating element is energy efficient and quick to heat to the desired temperature.

 

The Nano heating element is a multilayered nano thickness coating material which includes of tin, tungsten, titanium and vanadium with organometallic precursors like Monobuty l Tin Tri-chloride doped with equal quantities of donor and acceptor elements preferably antimony and Zinc at about 3 mol % deposited over the insulating coating layers and the ceramic glass from AME.

 

The material used to form the heating element is deposited onto a substrate by using a low cost spray method in an open-air environment. The material maintains a stable structure. Designed with a low risk of crack formation, and has high conductivity. The material maintains its heating performance at high temperatures for prolonged time periods. The material is deposited in multiple layers which are coated on the ceramic glass.

 

Thus nano thickness heating elements are reliable high temperature heating elements capable of performing efficient and consistent heating functions up to about 6000 C.

Cup Insulation

 

Using unique patent pending application design we reduce heat loss in conjunction with Nano Heating to reduce power requirement and increase time between charges.

 

Controller:

 

By designing circuit that is tightly packaged we have created design ideally suited for packaging and still maintaining temperature rise in PCBA within industry norms with protection from potential EMC damage.

 

USB charging connector

 

Designed to be water resistant with plunger contacts that are corrosion resistant.
