C&G Unit 204: Installation of wiring systems and enclosures
Published in Trevor Linsley, Basic Electrical Installation Work, 2018
Tools and equipment that are left lying about in the workplace can become damaged or stolen and may also be the cause of people slipping, tripping or falling. Tidy up regularly and put power tools back in their boxes (called ‘good housekeeping’). You personally may have no control over the condition of the workplace in general, but keeping your own work area clean and tidy is the mark of a skilled and conscientious craftsman.
Tapboost - the design for manufacture of a low voltage water pump to boost the poor domestic water flow rate
Published in Australian Journal of Mechanical Engineering, 2023
The following future works are recommended: A computational Fluid Dynamics (CFD) modelling software could be used to simulate liquid and gas flows quickly and easily to calculate product performance and capabilities. This would have been greatly useful in the design review stage of the project to determine how the design of the pump housing could be most efficient in creating the boosted flow required in the design specification.For future development of TapBoost, a way of changing the power source to a more environmentally friendly solution would be explored. This could be developed using a renewable energy source, like solar, to power the pump rather than using mains electricity.Work had begun on developing TapBoost to be battery powered. However, the product would need to be redesigned to accommodate a battery like a size used on a cordless drill or power tool. This would give the product an extended run time where it would not need to be constantly charged to achieve the necessary performance consistently.

The aim of the company developing a powder-actuated power tool was to increase its robustness. As very high amounts of energy are released (600 J, an impact drill generates about 5–10 J) when using this power tool, the safety requirements for such a system are very high. For the design engineers, this means that all potential functional and failure cases should be considered in the design. Initially, the analysis was performed using the Failure Mode and Effects Analysis (FMEA) (Stamatis 2003) which is required by law in the company’s development location. Due to the high degree of functional integration of the components in the system, it was difficult to identify and describe the embodiment involved in the functions that ensure functional safety. For supporting the analysis, the C&C2-Approach was used.

Why this more significant inaccuracy in the sagittal plane in the tibia? We do not have an answer. We have only unproven conjectures, such as the greater ease with which minor errors in the rotational placement of the tibial guide can go unnoticed, leading to alterations in the sagittal tibial osteotomy plane, the angular variability of the saw blade allowing the cutting groove of the jig and the influence of upward or downward movements of the saw surgical power tool by the surgeon or certain difficulty for homogeneous tibial cementation that may condition different cement thicknesses in the anterior and posterior parts of the tibial component.
