Non-Propelling Pencils TRIZ Cases
- Unpowered Crayon Shaper Using External Hot Air Melting
External hot air and a heat exchanger melt crayons for reshaping, avoiding internal power, circuitry, and added manufacturing cost.
- PLA/PBS Pencil Shaft Composition Balancing Strength and Sharpening
See how a PLA/PBS composite shaft preserves bending strength and sharpening ability while replacing less sustainable pencil materials.
- Layered Injection-Moulded Pencil Casing for Sharpening and Lead Integrity
Two plastic phases form layered zones that sharpen cleanly, protect the lead, and resist volatile component migration.
- WPC Pen Sleeves with Inner Barriers Against Component Migration
This case uses a migration barrier and adhesion promoter to preserve pen quality while retaining a polymer-bonded wood substitute sleeve.
- Active Pencil Tip for Digitizer Position Detection
An active tip module connects to a standard pencil lead to transmit signals, resolving digitizer detection limits for small diameter tips.
- Integrated Blending Stencil Pencil with Protective Sleeve
A wood-bodied pencil integrates a blending stump via a securing apparatus and protective sleeve for combined drawing and shading.
