Electrographic Process TRIZ Cases
- Movable Image Forming Unit with Automatic Locking Mechanism
An automatic locking mechanism secures the moving unit during cartridge changes, preventing unintended movement while maintaining operational simplicity.
- Developer Cartridge Stacking via Engagement Protrusions
Developer cartridges use wall engagement parts to enable stable vertical stacking, reducing storage space requirements.
- Cable U-Curve Diverts Liquid in Image Scanner
A retaining portion shapes a cable into a downward U-curve, causing spilled liquid to drop at the lowest point and preventing damage to internal electronics.
- Process Cartridge Shaft Opening for Developing Unit Pressure Stability
A process cartridge shaft and opening mechanism allow developing unit movement to maintain consistent pressure on the photosensitive drum.
- Movable Force Receiving Portion for Jam-Free Cartridge Mounting
A process cartridge uses a movable force receiving portion to rotate components during insertion.
- Cover Maneuver Lever Locking Mechanism for Reduced Opening Force
Independent locking members rotate about perpendicular axes to minimize space and force required for cover operation.
- Waste Toner Transport Unit Inclined Surface Compaction
An inclined transport path restricts waste toner movement to increase bulk density, eliminating the need for manual container shaking.
- Urethane Cleaning Blade for Electrophotography
A cleaning blade uses a cured urethane composition to achieve high hardness and low warping.
- Resin Supporting Frame for Exposure Unit in Image Forming Apparatus
A resin supporting frame holds a grounded metal wire to stabilize the exposure unit, preventing interference between positioning portions during cover movement.
- Ink Cartridge Heating Element Modification for Printer Compatibility
A recycling system detects mismatched heating elements in ink cartridges and burns them out to restore printer compatibility.
- Fan Casing Air Inlet Offset for Noise Leakage Reduction
Offset air inlet port blocks rotation noise leakage, suppressing housing sound levels.
- Process Cartridge Developing Unit Movable Linkage
Movable developing unit links to photosensitive drum via lower connecting portion to stabilize contact force and prevent deformation during image formation.
- Dual Limit Portions for Covering Deformation in Image Formers
Segmented limit portions constrain interior and covering angles to prevent deformation and user pinching risks.
- Rotating Operating Portion for Compact Image Forming Component Access
A rotatable operating portion retracts from the opening-closing portion trajectory to create a clear exit path.
- Process Cartridge Light Guide Positioning for Shutter Interference
A process cartridge positions a light guide incident portion outside the shutter rotation locus to enable reliable drum exposure.
- Modular External Cover for Image Forming Apparatus Coupling Mechanism
Identical cover members adapt to various post-processing device configurations, eliminating model-specific molds while maintaining exterior design integrity.
