Door/Window Protective Devices TRIZ Cases
- Variable Moment Arm Counterbalance for Rollup Doors
Movable drum attachment points adjust the moment arm length to reduce initial motor load and manage torque variations during rollup door operation.
- Tension Adjustable Retractable Screen Track Assembly
A tension adjustable retractable screen track assembly uses biasing members and mechanical fasteners to maintain screen tension.
- Blind Section Distance Sensor for Vehicle Component Interference
A distance sensor with a blind section reduces sensitivity to vehicle components.
- Arrester Device Eccentric Auxiliary Worm Gear
Eccentric auxiliary worm gear cancels offset to reduce assembly complexity while enhancing operating security.
- Compact Hinge Assembly for Vertical Panel Folding
Diverging slot system in elongated hinge member connects vertical panels while preventing alignment issues during unfolding.
- Rolling Door Governor Device Prevents Gear Abrasion Stalling
Clutch mechanism locks the hub upon detecting abnormal speed changes from gear abrasion, preventing rolling door stalling while protecting the transmission.
- Awning Winding Shaft Coupling for Fine Fabric Alignment
Split hub with internal toothing bridges pinion ends on coaxial winding shafts to enable precise rotational adjustment.
- Screen-Printing Panel Corner Softening via Locking Strip Gaps
Gaps between the locking strip end and mesh edge soften corners, preventing tearing during tensioning.
- Motorized Window Treatment Control Minimizing Occupant Distractions
A load control system schedules motorized roller shade movements to limit sunlight penetration distance within a building space.
- Blind Tilt Assembly With Dual Clutch Rings
A blind tilt assembly uses dual clutch rings to rotate separate slat sets via a single drive shaft.
- Double-Layer Cord Rolling Device for Window Blinds
Stacking the driving unit above the cord rolling unit reduces horizontal length, preventing interference with adjacent window blind components.
- Actuator Power Supply Standby Energy Elimination
Series coupling means charges storage element during operation to fully disconnect actuator from mains, eliminating continuous standby current draw.
- Adjustable Hysteresis Brake for Drive Shaft Torque Control
An adjustable hysteresis brake modulates braking torque by varying the distance between a static ferromagnetic element and a rotating permanent magnet.
- Adjustable Guide Structure for Roll-Up Fabric Tension
Roll-up fabric guide structure with adjustable interlocking means to accommodate varying transverse dimensions.
- Shading Device Locking Mechanism for Adjustable Fabric Tension
A shading device locking mechanism below the fabric plane adjusts stop positions via a transmission device activated by the drop rod.
- Wireless Curtain Closure System Adaptive Channel Selection
A wireless curtain closure system dynamically selects communication channels based on detected interference to maintain signal integrity.
- Blind Motor Control Unit Integrated Housing
Integrating the control unit into the blind motor housing eliminates on-site assembly time and reduces material costs.
- Built-in Blind Assembly Side Access Cord Driving Unit
Segmented top rail seat and repositioned cavity open side allow cord-driving unit installation without blocking user vision or requiring extra fasteners.
- Venetian Blind Slats with Airflow-Forming Structural Elements
Airflow-forming slats direct air upwards, resolving insufficient airflow management while improving solar heat utilization for heating.
- Motorized Sliding Gate Leaf with Internal Actuator
Nests actuating mechanisms within the gate leaf structure to eliminate rack complexity and reduce exposure to environmental damage.
