“…This type of tool typically loosens the connectors whose faces were crumpled. Earlier, it was certainly assumed that this connector was problematic in terms of ease of loosening [12][13][14]. The connector was cleaned with a metal brush, filled with «WD 40», a liquid to facilitate the loosening, and hammered with a hand hammer to transmit vibration loads.…”

This paper addresses the issue of difficulties in servicing the brake pipe connectors for passenger cars, the service life of which exceeds 8‒10 years, which is associated with the deteriorated loosening of connectors. The existing ways to loosen the connectors of brake pipes have been investigated, especially those whose dismantling is complicated due to the corrosion and contamination of mated surfaces as a result of their wetting when driving a car. A conventional structure of the connector has been analyzed, which is installed in that place of the car that is the most unprotected from moisture and dirt – on the brake cylinder. The conditions that do not contribute to its failure-free loosening have been examined. The design of a specialized split clamping ring wrench has been considered, which can transmit the greatest value of the torque to the connector when loosening it; sometimes, however, its predefined value would not suffice. A computer-based finite-element simulation was employed to derive the models of the deformation state for the node «connector ‒ wrench». Based on the analysis of the models of different deformation state of a specialized split clamping ring wrench, the required profile of the geometrically balanced locked hexagonal profile of the wrench was defined. The analysis of the efficiency of the tightening and loosening level is determined by comparing the numerical values of the torque, which is applied to the connectors of the brake pipes. The torque values are measured by a specially devised technique. The introduction of the developed measurement technique makes it possible to compare the efficiency of wrenches of different designs by analyzing the maximum values of torques, which the wrenches can transmit to the connectors. Taking into consideration the identified shortcomings in the structure of the brake pipe connectors, the shape of the connector has been designed that is free from the specified drawbacks. The new structure provides for the possibility of using a conventional carob wrench for loosening when the mated surfaces are exposed to contamination and corrosion

“…Broadly, reliability reflects user confidence in a product`s usability by ensuring satisfaction with its capability, readiness for on-demand service, and minimizing the cost of acquisition and ownership throughout its lifecycle. Moreover, the aforementioned approach would not succeed without a continuous improvement strategy and tools properly implemented at all stages of manufacturing (Mazur, 2019;Kozeń, 2019).…”

Customer satisfaction has long been an important concern for most organizations aiming to provide and ensure excellent quality products. To offer an appropriate level of quality assurance, it is necessary to have implemented a robust quality assurance system. Nowadays, mere customer satisfaction is not sufficient for organizations to sustain a mutually beneficial relationship. There has arisen a necessary requirement to go beyond customer satisfaction, aiming primarily to achieve a level of socalled cus-tomer delight. To attain sustainable product and process quality assurance and, consequently, customer delight, we must address process capability. This includes gauges, machines, and the overall process and product capability, with a specific emphasis on the design and development process, product reali-zation, and the initial flow. This also includes data gathering from the utilization stage of product opera-tion. This article deals with the capability study during the industrialization process of a new product into serial production, using chosen Key Performance Indicators (KPIs), particularly Capability indices and their sequence, to ensure the appropriate level of quality guarantee and customer delight. The article aims to broaden the existing set of Key Performance Indicators (KPIs) by incorporating crucial metrics from the quality domain, with a particular emphasis on Capability indices.

“…Social awareness and responsibility is of particular importance in the case of the service enterprises. It should be remembered that in case of services, the customer has direct contact with the enterprise and affects the characteristics of the ordered service (Klimecka-Tatar and Ingaldi, 2020;Rosak-Szyrocka, 2018;Mazur, 2019). Due to the customer's participation, the proper quality of the service, which he should accept, is created (Knop, 2019;Pilarz and Kot, 2018;(Ulewicz, 2016).…”

The enrichment of the society and the consumptive lifestyle caused that customers buy more and more, having different, often very high requirements as to the purchased products and services. They often do not realize that production of such products requires more and more materials, energy and other means of production. All this leads to high exploitation of the environment. Even if the resources of the natural environment are not exhaustible, they do not keep up with their rebuilding at this pace of exploitation. That is why social awareness and responsibility both of producers and customers play such an important role. They are one of the instruments needed to operate in accordance with the concept of sustainable development. The aim of the research was to examine social awareness and responsibility among customers of service enterprises. The research was conducted with the use of an online survey, which allowed to show whether the customers of such enterprises are interested in the concept of the sustainable development, if they take it into account when using various services. The need for environmental education was indicated, which could strengthen the social awareness and responsibility among Polish customers.
