Main deficiencies

The use of a soldering iron in manufacturing plants to solder connections and small components is accompanied by several challenges or problems. First, the tool is used to conduct work in a standing position, and in the process, workers lean forward leading to complaints of back and net pain from them. Second, most workers use the tool in a diagonal position, and this makes it difficult for the electrical connection to be contacted perpendicularly. This way, the workers use the side of the point of the iron instead of the tip of the iron’s point, and this leads to an undesired quality of work. Moreover, many a times, the workers hold the soldering iron with a strong grip making its handle be driven in the palm of the hand, an aspect that is highly discouraged. Complaints about palm irritation as well as pain are owed to the act of holding the tool’s handle too tightly or with a strong grip. The tool’s electrical cord also causes small accidents when it causes the frequent entangling of the tool that causes jerking of the hot iron on the hand of the person operating it. The other deficiency accompanying the tool is that it leads to complaints of shoulder and wrist pains as well as numbness in the hand for those who use it in their places of work (Skipp, 2010).

Redesigning the soldering iron such that it has a bent handle would be one of the best ways of helping eliminate the problems accompanying its use as mentioned above (Skipp & Heydn, 1997). The redesigning of the soldering iron handle is as shown below.

As shown above, the bending of the handle of the soldering iron is a special feature that would eliminate the challenge of having to bend the wrist as well as having to hold the handle with a strong grip that would end up interfering with the palm of the hand.

Moreover, the elimination of the above-mentioned challenges and deficiencies would be accomplished by lowering the work surface where the electronic wiring panel is placed. This is as shown below.  The work surface should be shifted from A to B to eliminate the deficiencies.

 

A                                              B

As seen above, the lowering of the work surface is a special feature incorporated in the solution, which would help eliminate the challenge of having to bend the elbow, the wrist, and having to position the neck and shoulders in an awkward manner(Skipp & Heydn, 1997).

Redesigning the handle to give it a bent handle would help solve problems and deficiencies accompanying the use of the tool.Such problems include the difficulty to contact the desired electrical connection perpendicularly, holding it too tightly causing it to be driven in the palm of the hand and the frequent entangling of the electrical cord that causes its jerking into the palms of the hand. A bent handle for the tool would also reduce the chances of the worker bending their wrists and instead work with their wrists in straight positions, and this would help eliminate complaints of wrist pains from the workers (Centers for Disease Control and Prevention, 2004). On the other hand, lowering the work surface would help eliminate the challenges accompanying the use of the tool. First, lowering the surface would allow the worker to position his shoulder and neck appropriately, and this would help eliminate the complaints of neck and shoulder pains from the workers (Centers for Disease Control and Prevention, 2004). Second, lowering the work surface would help reduce the frequency of the entangling of the electrical cord, and thus, the possibility of the tool’s hot iron jerking back into the hand of the operator would have been minimized.
