When a product or service has a significant “A” or “I” scenario, it is less important to rank the scenarios on the basis of tension in the supporting cable.
The “I” and “A” scenarios are more important than the other two on the chart. Instead of focusing on those two, we can focus on all four scenarios to create our cable design.
The remaining three scenarios do not have a very large difference in tension between their cables, so doing those three together will give us a full set of four cables.
This is important to know because if you only rank one out of four things, then you would be giving less attention to each thing. You would have to make assumptions about what things are like before making the cable connection.
Design scenario B: two cables supporting a light fixture
This is a possibility in which two cables support a fixture. One cable goes to the source of power, the second connects to the fixture.
This scenario has two possible tensions in the supporting cables. The first is between power and design, the second is between design and safety, the second being between safety and aesthetic concerns.
Power cables can be hard or soft. If they are hard, they can create heavy-handed aesthetics or strict rules for how wires should be arranged. If they are soft, you have more room for creativity and innovation.
Aesthetic issues may arise in whether or not this scenario accepts dual power cords, if one cord is thicker than the other, or if one cord has a cover over it to protect it from damage. Safety issues may arise in whether or not someone must have both eyes open to use this scenario with children running around as well asî|ⶩü¬»ü¬»ü¬»ü¬»ü¬> .
Design scenario C: three cables supporting a light fixture
This is the most tensioning of the cable scenarios. A supporting cable is connected to a light fixture, and the tension in the cables holds the fixture in place.
This scenario has three cables, each holding a portion of the support. Two of these cables are short and one is long. The short-and-long combination only makes sense if there are two sides to the support, right?
The combination of short and long Cable 1 holds a dimmer or puck switch for the light fixture. The combination of short and long Cable 2 holds an input wire for powering it down. The combination of short and long Cable 3 holds an output wire to send electricity to it or away from it to power other electronics.
Design scenario D: four cables supporting a light fixture
This is the most tensioning of the cable scenarios. It asks whether there should be four cables supporting a light fixture.
Many people would say no, two is enough. You have to move into housing with at least two basic cables (Internet, electrical, & TV) & two exterior walls to install a light fixture.
But if you did not have a light fixture, what would you do? Where could you put a shelf or display case? How could you make this scenario more inviting & cohesive with other scenarios?
In this scenario, one side of the light fixture is higher than the other. This creates an appealing contrast between dark and bright and gives this scenario some tension. If someone were to move in with this person, they might notice these details making them feel more comfortable & wanting them to enjoy their space.
Design scenario E: five cables supporting a light fixture
This is the most tension-filled scenario for a cable. There are five cables, each supporting a different amount of weight. These five cables must be placed in exactly the right order to create tension in the supporting cable.
This scenario is the most challenging as there are many ways to design this support cable. Some solutions include: Using two or more identical cables supporting the same weight, using an irregularly shaped cable supporting a single weight, or using no cable at all to support nothing.
Design scenario F: six or more cables supporting a light fixture
In scenario F, there are six or more cables supporting a light fixture. This can be a scenario for a power strip, six-foot power cord, or six-foot HDMI cord.
A is for interior or central air conditioning unit; B is for evaporative water coolers; C is for split-system watercoolers; and D is for roof-mounted watercoolers.
A is for interior or central air conditioning unit; B is for evaporative water coolers; and C is for split-system watercoolers.
In this scenario, two of the six cables support a light fixture, which creates significant tension in the supporting cables. This can be from the pull of the light fixture on its cable, or from the stress of being on top of an extended system with multiple components.
The other four cables do not appear to be under any significant stress, but are still recommended products such as power cords or HDMI cords.
Ranking of design scenarios based on tension in the cable
There are five possible scenarios for your cable to be in: A, B, C, D, and F. These scenarios differ in the tension in the cable between the two leads.
A is the softest scenario, where there is no tension in the cable. B and C are somewhat hardier, where there is a slight tension in the cable. D is the toughest scenario, where there is an excess of tension in the cable.
It can be difficult to tell which scenario your cable comes in, as they all look similar and most people would probably not notice them apart. However, if you were to take it out, then these differences could prevent a hazard from occurring or being prevented.
If you have a flat or sharp edge that could cause harm to someone if they were to step on it with their finger or toe, then this is one of the scenarios that should be avoided.
