Query/Challenge why NOT mod?

This is a type of Airpot (sic) sold by the millions throughout Eurasia cheaply made, most last a few years then go in the trash because they aren't worth fixing. This particular one cost me nothing 15 years ago being a 'freebie' when I purchased a monitor. For the past 6 months or so the diaphragm switches have become unresponsive to light touch, and a few weeks ago it seems the electric pump motor ceased to function. I took it apart and believe I can find replacement parts. I am prepared to spend a reasonable amount in fixing it, but for most people here in Thailand it isn't even a consideration, the cost of repair is not enough lower than replacement cost. Now, I've been sitting here looking at the puppy and thinking, "What might change that?" and keep these out of the landfill... I think it might make a difference if the 'repair' made it work better, cost less to use and made it last longer. My first thought was just to add insulation hopefully reducing energy consumption. Me, I'm weird so I also started thinking about not just replacing the membrane switches with better ones but also how can it be made more efficient and longer lasting? Some of my ideas might not be feasible or economically viable. I m not any kind of engineer. So I want to ask those of you who maybe are to consider what it would take to make these worth keeping around instead of tossing, or buying and fixing for resale by anyone wanting to make a few baht, rubles, yen, or what have you. For example, could a junk notebook cooling solution be repurposed as a heat pump to keep it warm? Would it be more energy efficient than the heating element, or add to the cost and represent another failure point? Solid state heat pump thingy? What if the readily available nitrogen gas people fill their tires with here were to replace the usual atmospheric air? Would the pump last longer? (Told you I'm weird) its cheap. But these are popular throughout most of the world, and seldom repaired. Thus the challenge how would YOU improve it, Cheaply. So people consider upgrading not just fixing, or am I off the mark?
