Introduction

In the world of dentistry, dental caries is a common problem caused by demineralization due to bacterial interaction. This problem can result in the emergence of cavities that must be corrected using composite resin material and dental devices. However, the use of these tools repeatedly can cause damage to the equipment, including Light Cure products. Based on a survey conducted at the dental clinic in Medan Selayang District, it was found that 5 out of 10 clinics experienced complaints related to light cure products. These complaints include a decrease in battery capacity, lamp age, material quality, hook button mechanism, and battery lock mechanism.

The use of Light Cure products is a crucial aspect of dental care, and any damage or malfunction can lead to significant financial losses and decreased patient satisfaction. Therefore, it is essential to design and develop Light Cure products that are durable, efficient, and meet customer quality expectations. In this article, we will discuss the design of Light Cure product repair using the Quality Function Deployment (QFD) and Value Engineering methods.

Understanding Customer Needs with Quality Function Deployment (QFD)

Quality Function Deployment (QFD) is a method used to understand and translate customer needs into relevant technical requirements. This method is essential in identifying the most critical customer needs and prioritizing them for improvement. In the context of Light Cure products, QFD can help identify the most critical technical requirements that need to be addressed to improve product performance and customer satisfaction.

The QFD method involves several steps, including:

Customer Needs Identification: Identifying the customer needs and expectations from the Light Cure product.
Technical Requirements Identification: Identifying the technical requirements that need to be addressed to meet customer needs.
Prioritization: Prioritizing the technical requirements based on their importance and feasibility.
Deployment: Deploying the technical requirements into the product design and development process.

Value Engineering for Cost Savings and Improved Performance

Value Engineering is a method used to analyze and check the design of components with a reference to its functional value. The aim is to get the same or better performance at a lower cost. In the context of Light Cure products, Value Engineering can help identify areas where costs can be reduced without compromising product performance.

The Value Engineering method involves several steps, including:

Functional Analysis: Analyzing the functional requirements of the Light Cure product.
Value Analysis: Identifying areas where costs can be reduced without compromising product performance.
Redesign: Redesigning the product components to improve functional value and reduce costs.
Implementation: Implementing the redesigned components into the product design and development process.

Case Study: Design of Light Cure Product Repair

A case study was conducted at a dental clinic in Medan Selayang District to design and develop a Light Cure product repair using the QFD and Value Engineering methods. The study involved several steps, including:

Customer Needs Identification: Identifying the customer needs and expectations from the Light Cure product.
Technical Requirements Identification: Identifying the technical requirements that need to be addressed to meet customer needs.
Prioritization: Prioritizing the technical requirements based on their importance and feasibility.
Deployment: Deploying the technical requirements into the product design and development process.
Value Engineering: Analyzing and checking the design of components with a reference to its functional value.
Redesign: Redesigning the product components to improve functional value and reduce costs.
Implementation: Implementing the redesigned components into the product design and development process.

The results of the study showed that the technical characteristics that are prioritized for improvement are product resistance and durability. Furthermore, the components that are considered to be immediately repaired are removable battery mechanisms and the main ingredients of the Light Cure product tube. The findings of value engineering analysis showed a significant potential cost savings. By replacing the battery component from Li-ion to NIMH and converting QTH lamps to LED lights, the total cost savings obtained reached 467%.

Conclusion

The design of Light Cure product repair using the Quality Function Deployment (QFD) and Value Engineering methods is a crucial aspect of improving product performance and customer satisfaction. The QFD method helps identify the most critical customer needs and prioritizes them for improvement, while the Value Engineering method helps identify areas where costs can be reduced without compromising product performance. By combining these two methods, companies can redesign Light Cure products that are not only more efficient in cost but also meet customer quality expectations. The end result is a product that is more durable, efficient, and ultimately provides higher satisfaction to the user.
