August 19, 2025, China - As smart homes become increasingly integrated into daily life, safety and reliability have become paramount considerations for consumers choosing smart locks and smart doors. As an innovation leader in the high-end smart security sector, Tenon today officially unveiled its "Four-Pillar Quality Assurance System," comprehensively revealing its full lifecycle quality control standards from product design and supply chain management to manufacturing and market feedback. This system redefines the quality benchmark for smart locks and smart doors through exceptionally rigorous standards.
Pillar One: New Product Introduction (NPI) – Eliminating Risks at the Design Stage
Tenon believes that exceptional quality begins at the source. Even before a new smart lock or smart door is conceived, Tenon employs Design Failure Mode and Effects Analysis (FMEA) to proactively identify and assess over 200 potential design failure modes, eliminating risks from the outset.
To ensure product stability under all extreme conditions, Tenon conducts Design Verification (DV) testing that far exceeds national standards, encompassing over 180 rigorous environmental tests, including:
- Salt Spray Test: 96 consecutive hours of testing to verify anti-corrosion performance;
- High and Low Temperature Test: Simulating extreme environments from -40°C to 80°C;
- Water Spray Test: Comprehensive evaluation of the waterproof and moisture-proof capabilities of the smart lock mechanism and door structure;
- Door Opening and Closing Durability Test: Accumulating 200,000 cycles of operation, simulating over 10 years of high-frequency usage.
Pillar Two: Production Validation (PV) – The Ultimate Pre-Mass-Production Test
Only products that pass the most stringent screening proceed to mass production. Tenon mandates that all new products must pass the Production Validation (PV) assessment, requiring a comprehensive pass rate of 98% or higher before entering large-scale manufacturing, ensuring every product brought to market withstands the test of time and environment.
Pillar Three: Supplier Quality Management (SQM) – Controlling Quality at the Source
Tenon understands that exceptional products depend on an exceptional supply chain. The company has established a four-dimensional evaluation system (Quality, Cost, Delivery, Service) for rigorous supplier screening and dynamic management. Through a monthly QCDS dynamic scoring mechanism, the supply chain ecosystem is continuously optimized.
All critical components undergo 100% Incoming Quality Control (IQC) inspection before being admitted into inventory, ensuring every chip and circuit board meets Tenon's high standards.
Pillar Four: In-Process & Dispatch Quality Control (IPQC & DQC) – Intelligent Manufacturing, Full Process Control
Tenon utilizes a fully automated SMT dust-free workshop, creating a "dust-free hatching ground" for high-precision chips, eliminating contamination risks during production. The production line achieves 100% online full inspection, ensuring no product is overlooked.
Prior to shipment, Tenon implements Dispatch Quality Control (DQC), conducting 100% comprehensive inspections on sampled products and re-performing over 180 extreme environmental tests to guarantee every product shipped is a premium product.
Pillar Five: Market Quality Management (MQM) – Driving Continuous Improvement with User Feedback
The ultimate test of quality lies with the user. Tenon has established a Customer Satisfaction Index (CSI) system, collecting genuine user feedback through multiple channels including e-commerce platforms, distribution networks, and engineering projects. The company has built an information-sharing database, enabling joint improvement initiatives with R&D, production, and service teams, supported by a professional service team offering 24-hour rapid response, truly embodying a "user-centric" philosophy.
Conclusion: Because of Your Trust, We Never Take Chances
From design to delivery, from core components to complete door systems, Tenon consistently upholds the principle of "Reliability Forged in Rigor." The company has accumulated over 100 technical patents and multiple international authoritative certifications. Every Tenon smart lock and smart door is a testament to its commitment to safety.
A Tenon executive stated, "We deeply understand that users entrust us with their home security. Therefore, we cannot afford even the slightest complacency. It is this sense of reverence and persistence that drives us to continuously push the limits of quality, creating truly trustworthy smart security solutions for users worldwide."
