Positioning
Not a single-product seller. A practical engineering team for new hardware programs.
The XL-001 massager is shown as proof of full-machine development capability. The broader service is helping overseas customers define, design, prototype, debug, and prepare new healthcare, wellness, wearable, personal-care, and connected hardware products for production.
Extended Scope
Small and medium consumer hardware involving sensors, motors, batteries, Bluetooth, firmware, housings, ergonomics, and production engineering.
Best-Fit Customers
Founders, product teams, overseas brands, sourcing teams, and engineering managers who need a Shenzhen-based partner to move from concept to manufacturable product.
What We Can Do
Engineering support across the full hardware development path.
Product Definition
Clarify target users, core functions, product architecture, cost targets, manufacturability risks, and development priorities before detailed design starts.
Mechanical & Industrial Design
Full-machine structure, ergonomics, air/liquid paths, sealing, thermal paths, moving parts, enclosure design, tooling direction, and assembly logic.
Electronics & Firmware Coordination
Sensors, motors, pumps, batteries, PCBA layout constraints, Bluetooth modules, embedded firmware logic, debugging, and system integration.
AI-Enabled Hardware
AI-assisted functions for connected devices, intelligent monitoring, user feedback loops, data-driven product logic, and smart wellness systems.
Prototype & Testing
Prototype planning, fit and function review, user experience checks, pressure/temperature/audio/control debugging, and design iteration.
DFM & Cost Control
BOM review, supplier communication, production documentation, assembly risk reduction, quality checkpoints, and practical cost reduction.
Case Studies
Real products, real engineering constraints, real production thinking.
These cases are not just product photos. They show how Xianglong handles structure, electronics, firmware, control logic, user experience, and manufacturability as one complete system.
Own Product Development
XL-001 Smart Eye & Head Massager
A complete wellness hardware product combining pneumatic pressure, heating, Bluetooth audio, voice prompts, detachable lining, adjustable wearing structure, and multiple operating modes. This project demonstrates full-machine development from concept through mechanical structure, control logic, user experience, and production preparation.

Four industry-exclusive functions · patent applied
- Near-silent massage, close to the feel of human hands. The piezoelectric ceramic pump itself produces virtually no noise, and the pump sits outside the mask connected by a slim, long air tube that further blocks noise. The design is modular: plug in the external pump for pneumatic massage, unplug it when not needed — the mask still works with music and heating.
- Position-adjustable temple & Fengchi (GB20) air bladders. The two bladder pads for the temples and the Fengchi points slide to fit the user's head size, so the massage reaches the right acupoints precisely for every customer.
- Dual pressure sensors for precise 20–200 mmHg control. Two pressure sensors independently detect and control the two bladder groups across 20 to 200 mmHg, precisely matching different users' pressure preferences.
- Open-and-close eye cover. Flip it open to massage while working; close it for complete light-blocking rest.

NICNOL Nitinol Silent Heating Massage Belt & Leg Sleeves
A self-developed wearable heat-care line built on nitinol (nickel–titanium shape-memory alloy) wires. When powered, the wires heat up and contract; when powered off, they cool and release. This contraction–release cycle delivers a rhythmic compression massage with no motor and no pump — completely silent. The fabric also outputs gentle heat together with strong near-infrared and far-infrared energy, well suited to elderly users and people living in cold, damp regions.

Utility model patent granted
Prototype stage — tooling not yet started
- Nitinol shape-memory wires drive the massage: heated contraction and cooled release form a silent squeeze-and-release cycle that replaces motors and air pumps.
- No motor, no pump, no vibration noise — suitable for night use and quiet environments.
- Warming care with strong near-infrared and far-infrared output for a comfortable thermal-therapy feeling.
- Soft, light belt and leg-sleeve forms designed for elderly users and for everyday wear in cold and damp climates.
Distribution, agency & private label welcome
All three of our own products — the XL-001 smart eye & head massager, the patented NICNOL nitinol belt & leg sleeves, and the dragon atomizing pendant — are open for sales agency / distribution, private-label (your brand) and OEM/ODM cooperation. All terms negotiable — contact us to discuss.

Phase 2 Product Development
Phase 2: Smart Refill, Storage & Charging Case
The pendant is currently refilled with perfume manually. In Phase 2, a dedicated smart case will store the fragrance pendant, automatically refill it, and stop automatically when the liquid level reaches full. The case will also provide voice announcements and automatic charging. The overall concept is now largely designed and will be presented publicly in Phase 2.
Automatic refill
Auto-stop at full
Voice announcements
Automatic charging
- Phase 1: refill the pendant manually with perfume.
- Phase 2: the smart case combines storage, automatic refill, and charging.
- Liquid-level detection stops the refill automatically when full, with a voice announcement for the user.
The Phase 2 concept is largely designed; final functions and engineering parameters remain subject to validation.

AI & Machine Learning
From embedded engineering to applied AI that actually ships.
I completed the full Machine Learning and Deep Learning Specializations taught by Professor Andrew Ng (Coursera · DeepLearning.AI) and earned 10 course certificates. Combined with 29 years of embedded and hardware experience, this means I can help customers train small models and put AI into real products: visual inspection, sensor data analysis, predictive maintenance, edge deployment on MCUs, and more.
