As a 15-year biotech leader in scalp care, KimDai identified critical flaws in traditional roller-ball systems through quantitative lab tests and user behavior analysis:
30% Active Ingredient Loss: Mechanical friction and oxidation in roller-ball structures.
68.6% Absorption Rate: Rigid designs failed to adapt to scalp curvature.
OPD-Design’s medical-grade industrial design framework reimagined these challenges, targeting ＞90% delivery efficiency while transforming a clinical tool into a luxury self-care device.
Using TRIZ contradiction matrix analysis, we engineered a 3-tier solution:
MEMS Atomization Core: Replaced roller-balls with microelectromechanical systems for 8μm mist precision (vs. 150μm droplets in traditional systems).
Self-Cleaning Mechanism: 20,000rpm titanium blade (Patent ZL2023XXXXXX) prevents clogs in high-viscosity formulas.
Ergonomic Scalp Mapping: 16-point pressure sensors adjust mist density for Asian scalp curvatures.
Using TRIZ innovation methodology, we integrated microfluidics, mechanical dynamics, and electronic engineering:
Mechanical Design Breakthrough: Replaced traditional roller-ball mechanisms with MEMS-based microelectromechanical systems;
Industrial Design Empowerment: Defined a 47° golden grip angle based on scalp curvature big data (100,000+ Asian user models).
Morphological Semantics: Inspired by “plant root systems,” the fractal flow channel housing symbolizes natural hair growth;
Mechanical Aesthetics Visualization: Sapphire glass windows expose precision atomization components to enhance technological trust.
Piezoelectric Ceramic Drive System:
Optimized vibration frequency (15kHz±2%) via ANSYS mechanical dynamics simulation to adapt to 20-500cP viscosity liquids;
Self-Cleaning Blade Mechanism (Patent No. ZL2023XXXXXX):
A 20,000rpm titanium alloy blade driven by a micro-motor eliminates high-viscosity liquid crystallization blockages.
Zero-Residue Delivery System:
3D topology-optimized titanium alloy atomization chamber with ±0.05mm wall thickness precision;
IPX7 Waterproof Structure:
Seamless housing via nano-injection molding, enduring 72-hour salt spray testing without performance degradation.
Dynamic Pressure Sensing System:
16-point matrix sensors monitor scalp contact in real time, automatically adjusting mist density;
Bionic Handle Design:
Reduced grip fatigue by 62% through DELMIA human factor engineering simulation.
Aerospace-Grade Materials:
6Al-4V titanium alloy atomizer nozzle offers 200% higher strength than stainless steel;
Bio-Based Resin Housing:
BASF Ultramid® Balance material reduces carbon footprint by 43%;
Sandstone-Touch Coating:
1200-grit surface treatment enhances anti-slip performance and medical-device professionalism.
Transdermal absorption efficiency increased to 93.4% (third-party lab verified);
Atomized particle size Dv90 <8μm (Malvern Mastersizer certified).
User Experience Upgrade:
40% shorter care time, with 50,000 units sold out during pre-sales;
Industry Standard Redefinition:
Featured as a benchmark case in the 2023 China Medical Device Industrial Design White Paper.
OPD-Design achieved three innovations for KimDai through “mechanical-electronic-material” cross-domain collaboration:
Medical Mechanical Design Paradigm Shift: Introduced ±0.01mm tolerance control to consumer electronics;
Industrial Design Scenario Reengineering: Transformed medical treatment into ritualistic self-care experiences;
Sustainable Design Value: Bio-based materials and modular structures reduced lifecycle environmental impact.
This project not only redefined technical standards for scalp care but also validated the fusion of “precision mechanical engineering and empathetic human-centric design” in medical consumer electronics.
