Introduction

Today's consumer goods are changing with each passing day, with rapid upgrades and iterations, and the structures and functions of some consumer goods are becoming more and more complex. Reliability is responsive consumer goods One of the important indicators of quality characteristics, especially in the safe operation of durable consumer goods, long-term use and easy maintenance. consumer goods in During use, product failure or failure will affect the use of consumer products and reduce customer satisfaction. Reliability improvement is the improvement of consumer product quality. core. With the fierce market competition and consumers' requirements for product quality improvement, the improvement of consumer product reliability will become a product for enterprises to improve. The inevitable way out for quality and market competitiveness.

In some complex product manufacturing fields, such as defense and military industry, the improvement of product quality and reliability has accumulated rich experience. That The core is to use the "planning-implementing-checking-handling" of quality improvement with the help of the Failure Reporting, Analysis and Corrective Action System (FRACAS).

(PDCA) cycle to drive reliability improvements. Relevant experience started in recent years in more complex consumer products containing electronic and/or mechanical components It has been popularized and applied in reliability improvement and achieved good results.

The reliability improvement of consumer products takes failure as the core, and starts with the import, analysis and utilization of quality assurance data in the use stage, and in the existing quality management In the system, FRACAS and the corresponding operation and management mechanism are established to apply the fault information from the quality feedback from the market to the equipment.

In the planning, production and other stages, realize the reliability improvement of batch products, modified products and new products, and make the reliability improvement form an effective closed loop. Consumer Product Reliability Improvement Guidelines Based on Warranty Data
