1Use of energy by moving object
If a thermoelectric generator is integrated to harness temperature differences for power generation, then renewable energy utilization is improved, but device complexity increases
Solution Approach 1:
The TEG system utilizes the natural temperature difference between the ATM interior and exterior environment to generate electricity, making the system self-powered without requiring external power sources or complex control mechanisms. The temperature gradient that naturally exists during ATM operation is converted directly into electrical energy for powering components.
Solution Approach 2:
The patent replaces conventional mechanical power generation systems with a solid-state thermoelectric generator that has no moving parts. This substitution eliminates the need for complex mechanical components, lubrication systems, and maintenance mechanisms while directly converting thermal energy to electrical energy through the Seebeck effect.
2Power
If multiple TEGs are connected in series to enhance power output, then power generation capacity is improved, but device complexity and space requirements increase
Solution Approach 1:
Multiple TEG modules are connected in series configuration to combine their individual power outputs into a unified electrical generation system. This merging approach allows the ATM to achieve sufficient power capacity by integrating several small-scale TEG units into a single functional system that powers multiple components simultaneously.
Solution Approach 2:
The TEGs are strategically positioned on different surfaces and orientations of the ATM housing, utilizing three-dimensional space around the device. By placing TEGs on various exterior and interior surfaces that experience temperature differentials, the system maximizes power generation capacity without requiring additional interior space or complex mounting structures.

Function Achieved in This Case
The TEG system effectively generates renewable energy to power ATMs, reducing reliance on external power sources and optimizing energy consumption.
Implementation Method 1
A thermoelectric generator (TEG) converts heat into electricity using the Seebeck effect. When there is a temperature difference across a thermoelectric material, charge carriers (e.g., electrons) move from the hot side to the cold side, generating an electric current.

AI summary
A system and technique may be used to generate power via a thermoelectric generator (TEG) at a through-the-wall automated teller machine (ATM). An example system may include a thermoelectric generator (TEG) configured to harness a temperature difference between an interior portion of the through-the-wall ATM and an environment external to the through-the-wall ATM to generate energy to power small devices in the through-the-wall ATM. The TEG may include a first face exposed to the interior portion of the through-the-wall ATM and a second face opposite the first face, the second face exposed to the environment.
