Tracing Power Lines with the Pylon Appreciation Society
Pylons
Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
A haunting, syncopated music
"Rappers" on the roof of the electrostatic precipitator knock the accumulated dust free, letting it fall into the storage hopper. Each rapper is the size and shape of a baseball bat. Inside is an electromagnet that pulls a steel plunger upward, then allows it to fall again, producing a sharp knock. The rappers are energized at seemingly random intervals, producing a haunting, syncopated music. (The rhythm seemed more modern jazz than rap.)
Safety cut rope axe man
In the first nuclear reactor, constructed by Enrico Fermi in 1942 under the bleachers of the University of Chicago football stadium, the control rods were held up by a manila rope. A man with an axe was told to cut the rope if the reactor got out of hand. This "safety cut rope axe man" is supposedly the origin of the term SCRAM for an emergency shutdown procedure.
Color coding
Telephone wires erupt in a multicolor cascade in a ground-level, pedestal-type splice case on a city street.
Dividing the set of 10 colors into two contrasting groups of 5 allows for exactly 25 combinations with one color from each group; thus, each pair in a bundle can be uniquely colored. A similar color code is applied to the ribbons that bind together all the pairs in a bundle, and to those of the superbundles. The result is highly festive! A specific wire might be identified as the blue-red conductor within the orange-black bundle within the brown-yellow superbundle.
Pair Design: Better Together
Pair design is the counterintuitive practice of getting more and better UX design done by putting two designers together as thought partners to solve design problems. It’s counterintuitive because you might expect that you could split them up to work in parallel to get double the design done, but for many situations, you’d be wrong. This document will help explain what pair design is, how it works, and tour through the practicalities of implementing it in your practice.
It involves two brains
It involves two brains on a project at the same time. This doesn’t mean part time, checking in with each other on work that’s been accomplished separately.
Pair design really means being in the same room, working on the same problem, with both brains focused on the problem simultaneously for the duration of the project.
A distinct and complementary stance
Each person in the pair takes a distinct and complementary stance toward the design problem as they work together. One generates solutions. That is, one individual materializes solutions to the problem at hand for discussion and iteration. The other synthesizes the proposed solutions.
Gens and synths
Gens are generally comfortable drawing and drawing in front of their partner. Additionally, the generator needs to have “fearless generativity,” to be able to come up with a dozen pretty good solutions to a problem even with incomplete information.
Designers in the synthesizer role need to be skilled at describing designs and explaining rationale in writing. The role requires the designer to be detail oriented and have a strong memory, to keep the big picture of the system, stakeholders, and users in mind as a reference for designs on the table.
We come as a team
There is a legend at Cooper of one team who found pairing with each other so powerful and fruitful that when they left that company, they sought out opportunities and even interviewed at other organizations as a pair.
Starting off with pair design
It’s better to start small. Find the “genniest” designer you can and pair her with the “synthiest,” have them work through a few projects as a pair to see how it goes, evolve a process that works for your organization, smooth out the wrinkles, and become resident experts. Then, split them up, assign them with new pairs, and begin to spread.
What are the benefits of pair design?
It Makes for Better Design
- Pairing forces constant iteration: idea testing and course-correction.
- It brings to bear two brains and two stances.
It Makes for Better Designers and Better Design Organizations
- They are happier.
- Pair design makes it easier to focus on core aptitudes.
- They cross-pollinate: a mechanism for a learning organization.
Pair Design Makes for a More Effective Process
- Pairing avoids the problem of dueling whiteboards.
- It encourages designers to materialize ideas early.
- It encourages designers to vocalize their rationale.
- It encourages constant course-correction.
