Filament Handling TRIZ Cases
- Hands-Free Toilet Paper Dispenser Cover for Hygienic Wall Rollers
A sensor-triggered motorized cover fits over existing wall-mounted toilet paper rollers to cut hand contact, improve hygiene, and reduce waste.
- Rolled Product Dispenser With Elastomeric Fins for Rotation Control
Elastomeric fins frictionally engage the roll tube to prevent uncontrolled rotation and unraveling without complex braking parts.
- Two-Roll Toilet Paper Dispenser With Automatic Roll Transfer
A sensor plate and pivoting mandrel shift the standby roll into place automatically while retaining spent cores and simplifying reloading.
- Integrated Toilet Paper Holder With Parallel Fluid Dispenser
A parallel pump-and-container layout combines toilet paper holding with fluid dispensing to simplify construction, lower cost, and improve reliability.
- Dispenser Retention Slot Geometry for Wrong Roll Rejection
A narrowed insertion slot and rejecting slot admit only correctly sized bearing pins, blocking wrong rolls without moving parts.
- Rack Cable Guide With Offset Stays for Easy Secure Routing
Offset brackets and overlapping guard members let rack cables slip in and out easily while staying securely routed with less manual effort.
- Paper Dispenser Roll Sensing for Easier Front Paper Access
A gravity-return sensing element frees paper outlet placement from the rear wall, improving access and roll-change design flexibility.
- Paper Dispenser End Sensor Placement for Accurate Reel Switching
Positioning the end sensor after the roller nip keeps the paper web taut, avoids false empty alerts, and enables automatic reserve reel change.
- Paper Dispenser Spare Roll Transfer in a Narrow Housing
A diameter-sensing blocker lets a spare roll drop only after it shrinks, saving housing space and preventing dispenser jams.
- Center Pull Dispenser Roll Support for Low-Material Indication
A stepped roll support lets the center pull roll drop under gravity as material runs low, giving a simple visual refill cue without linkages.
- Roll Core Insert Identification for Authorized Web Dispensing
A conductive roll-core insert shifts coil frequency to verify approved web rolls, block unauthorized use, and reduce dispensing waste.
- Wiping Material Dispenser Hatch for Safe Jam Clearance
A removable hatch gives direct access to the dispenser feeding unit, clearing paper jams faster while keeping moving parts shielded.
- Paper Dispenser End Detection Behind Transport Rollers
Positioning the paper-end sensor behind the roller nip prevents false low-paper signals, cuts waste, and enables automatic reserve reel change.
- Tissue Dispenser Carousel With Reserve Roll Transfer
A rotatable carousel and self-actuating transfer mechanism keep low-basis-weight tissue dispensing reliable when the primary roll is depleted.
