In my last article (CFN November 2012), I described an industrial design class at the Rhode Island School of Design (RISD) in which students were asked to innovate gear for the lobster industry that would be both serviceable and reduce the risk of injury.\u00a0 This process, called \u201cprevention through design\u201d in the industrial hygiene field, involves consideration of how the body moves and how it interacts with tools, clothes, and other elements in the environment.<\/p>\n

Early in the academic term, instructor Thomas J. Weis from Rockland, ME divided the class into four groups:\u00a0 \u201cwearables,\u201d tools, accessories, and workstation.<\/p>\n

In the wearables group, the students discussed the disadvantages of the current yellow oilskins that most lobstermen wear, noting that the shoulder straps of the overalls bear all the weight, the material is bulky at the waist and ankles, and the bib front gets a lot of wear and tear.\u00a0 The hood of the rain jacket, they noticed, reduced deckhands\u2019 ability to see to the side when the head was turned.\u00a0 Furthermore, in cold weather, lobstermen often had to wear a cap under the hood.<\/p>\n

This team designed three different wearable items.\u00a0 The first was a one-piece suit, the overalls of which were made of thermoplastic polyolefin (TPO) coated polypropylene with an attached Polartek\u2122 fleece shirt.\u00a0 Both of these materials allowed the suit to fit close to the body.\u00a0 Velcro\u2122 straps at the ankles provided a snug fit, and optional closed-cell padding was available to insert into pockets on the thigh to cushion contact with the trap.<\/p>\n

The second was a bibbed pant built for durability, comfort, and longevity with a reinforced leather-like vinyl chest piece.\u00a0 The pants were lightweight and water-resistant with waterproof zippers.\u00a0 Zippers were added at the ankle to reduce bulk.\u00a0 The optional thigh padding was made of the same dense plastic material used in ice hockey suits.<\/p>\n

The third wearable was a lightweight hat made of a new material called \u201ceVent\u2122\u201d that lets sweat through and never becomes wet.\u00a0 This hat cleverly snaps on to the inside of a Grundens\u2122 hood and stays in place.\u00a0 The Grundens\u2122 hood was redesigned with clear plastic panels to permit easy viewing when the head is turned and, when the lightweight hat was properly snapped inside the hood, the hood movement was controlled, allowing improved peripheral vision.\u00a0 The students also designed a summer version with snap-on flaps to protect the back of the neck from sunburn.<\/p>\n

These three wearables clearly addressed some of the downside issues of oilskins and were attractive and very well made.<\/p>\n

Tools, accessories<\/b><\/p>\n

The two students in the \u201ctool\u201d group worked on knives and banders, items I had the chance to try out.\u00a0 I preferred a \u201chollow\u201d knife design, which allowed me to put my hand through the open handle and grip it tightly.\u00a0 The design seemed to reduce the chances that the knife would fly out of my hand if I had to forcefully cut myself free from a rope entanglement.<\/p>\n

The bander featured an angled design that reduced wrist \u201cflexion,\u201d the bending down of the wrist, when picking up a band.<\/p>\n

Additionally, the handle was slightly longer than normal so that the little finger could be put to use, thus distributing the force of the squeeze across the whole hand.\u00a0 A comfortable covering on the handles eliminated the bite of the current bander\u2019s metal edge against the hand.<\/p>\n

One of the two students in the \u201caccessories\u201d group designed a ridged plastic strap for the thigh to help stabilize the trap against the thigh when lifting and carrying traps.<\/p>\n

This thigh pad accessory was accompanied by a demonstration of proper lifting technique, which involves keeping the trap close to the body and using the knees, not the back.<\/p>\n

The other student designed gloves that featured padded fingers inside and a reinforced leather pad outside in the thumb-palm area.\u00a0 A slight indentation in the palm padding cushioned the handle of the bander.\u00a0 These were great improvements, but probably not practical for various reasons.<\/p>\n

 <\/p>\n

Workstation<\/b><\/p>\n

Finally, the three-student workstation group presented some \u201cway-out\u201d designs.\u00a0 One was an upright banding board with multiple built-in mechanical banders that allowed bands to be preloaded onto the board.\u00a0 During banding, the lobster claw would be inserted into a mechanical device that opened to expand the band and closed when the claw was removed.<\/p>\n

I appreciated how the student was concerned about painful repetitive motion injuries to the wrist that so many lobstermen experience.<\/p>\n

Another student designed a \u201cquick-on, quick off\u201d set of wheels to be installed between the openings in the trap, enabling a lobsterman to roll his traps to reduce the risk of back injury.<\/p>\n

The third student, who noticed that lobstermen are always leaning on the rail or the bait box for stability, designed a C-shaped, padded support that slid onto the bait box.\u00a0 When standing in the \u201cC\u201d at the bait box, the lobsterman is surrounded at the front by a padded \u201chug.\u201d\u00a0 If the lobstermen turns around, he can rest his elbows on the ears of the \u201cC\u201d and get a relaxing back rub from the padded form.<\/p>\n

Throughout this delightful design exposition afternoon, the students demonstrated how they researched, designed, and redesigned until they had a viable product.\u00a0 It was a pleasure to see how carefully they sketched and built these items.\u00a0 Now, we\u2019ll see if anyone is interested in manufacturing any of them for the industry.<\/p>\n
