Pros,cons and modifications- 4 configurations of the IRS tank

Concept	Advantages	Disadvantages	Modification
Shoulder mounted tank	-Quick to take off and on. -Able to use in confined spaces -Able to agitate the tank when needed.	-All the weight is distributed onto one shoulder. -Pump in awkward position. -Have to take tank off shoulder every few minutes to agitate the tank. -Unable to tell how much liquid is left. -Unable to tell exactly how much water to put in. -Foot stand is inefficient.	- Tank attached to some kind of lever mechanism that allows the user to tip the tank back and forth without taking it off and on. -Add pump to spray gun instead of on tank. - Add transparent panel so user can estimate the amount of liquid left. -Add a foot stand on either side.
Back mounted tank	-Weight better distributed -Able to use in confined spaces. -Possibly able to carry 2 tanks, or larger capacity. -The user has more use of both their hands.	-Harder to agitate the tank. -Have to take off to see how much liquid it in the tank. -Still have to take off to use pump. -May case back strain.	-Add pump to spray gun instead of on tank.
Head mounted tank	-Able to carry a larger capacity. -Better weight distribution. - The user has more use of both their hands. -Ingrained in culture/society.	-Difficult to use in low and confined spaces. -Extra training may be needed. -Have to take tank off and on to constantly agitate tank.	-Add a spinning mechanism so tank can be agitated.
Rolling sphere tank	-Able to hold a larger capacity. -Weight problems are no longer an issue. -Less strain on the user. - Constantly being agitated, no need to stop spraying every few minutes. -Able to walk longer distances.	-Could be more prone to damage. -Product prone to becoming dirty, added time to clean equipment. -May be difficult to transport over certain terrains. -May take up one of the users hands. -Can’t see how much liquid is in the tank.	-Attach orb to user with harness to free up hands. - Add transparent panel so user can estimate the amount of liquid left.
