Pen Repairing TRIZ Cases
- Ball Pen Tip Spring Assembly Using Plastic Flow Ridges
Plastic flow ridges formed by rear-end punching let ball pen tip springs assemble without directional alignment, improving speed and reliability.
- Click Pen Inner Cylinder Assembly for Secure Rotor Retention
An elastically deformable inner cylinder cuts assembly friction while keeping the rotor and rear shaft securely engaged during refill replacement.
- Wooden Writing Barrel with Paper Straw for Core Pin Release
A paper straw inner layer cuts friction on the core pin, enabling distortion-free release in molded wooden writing barrels.
- Writing Instrument With Radial Flexure for Rotor Retention
Radial flexure lowers insertion friction during assembly, then restores rotor retention to prevent unintended detachment during handling.
- UVC Disinfecting Chamber with Rotating Floor and Reflective Liner
A disinfecting chamber uses UVC light and a rotating floor to deactivate contaminants on complex objects.
- Modular Marker Assembly Kit with Press Mechanism
A marker assembly kit uses a press mechanism to secure reservoirs inside barrels.
- Decoupled Display Control for Flexible Processing Systems
Decoupled display units with integrated operator software allow concurrent data entry, resolving the trade-off between device complexity and adaptability.
- Ballpoint Pen Tip Ink Groove Design for High Viscosity Flow
Segmented ink guide holes and radial grooves prevent spring jamming while sustaining reliable fluid outflow for high viscosity inks.
- Flat-Pen Assembly Line Automation with Pneumatic Pressing
Automated flat-pen assembly line uses pneumatic cylinders to press caps onto barrels via an endless loop chain.
- Ballpoint Pen Refill Thickened Press-Fit Ends
Thickened press-fit ends attach tips to cylindrical ink tubes, balancing storage capacity with mechanical strength.
- Ball Point Tip Leaf Spring Ink Flow and Leakage
A plastic ball point tip uses a leaf spring to press the writing ball against the ink conduit, resolving gel ink leakage while maintaining smooth writing.
- Spring-Biased Valve Liquid Applicator Closure
Segmented closure design reduces part count while maintaining reliable flow control through a self-service spring mechanism that prevents accidental discharge.
- Detectable Refill for Writing Implement
Infusing refill walls with detectable particles resolves the contradiction between component separability and contamination detection reliability.
