Domestic Articles TRIZ Cases
- Bottle Blowing Mold Opening Linkage Replacing High-Wear Spatial Cams
A four-bar and crank-slider mechanism replaces precision-heavy spatial cams to reduce vibration, impact, and component wear.
- Foamed Resin Pallet with Selective Resin-Sheet Reinforcement
A vacuum-formed resin sheet reinforces pallet surfaces while the uncovered loading face preserves foamed-resin insulation and cushioning.
- Three-Injector PET Injection for Stable Bottle Preform Flow
A third injector buffers valve switching in PET preform molding, maintaining pressure and limiting hydraulic shocks and plastic degradation.
- Mold Sliding Surfaces With Embedded Solid Lubricants for Galling Prevention
This case embeds solid lubricants in neck-mold sliding surfaces to prevent galling, reduce upkeep, and preserve precise positioning.
- Bottle Preform Grip Interface for Rigid Sliding Handle Attachment
This case uses preform guide ribs and grooves for secure, oriented handle attachment after blow molding.
- Multi-Layer Plastic Components from One Tool with Variable Foam Contours
A removable spacer layer varies foam thickness and contour stability, producing soft, accurate multi-layer plastic variants with one tool.
- Plastic Tub Forming With Nestable Frames for Uniform Thickness
A two-frame forming device reduces friction during plastic tub bending, improving thickness uniformity without manual polishing.
- Sewn Positioning Body for Semifinished Fiber Products
A sewn, low-cost positioning body supports transport and processing alignment while reducing scrap from oversized fiber-product recesses.
- Two-Color Injection Mold with Rotating Slide Cores
Rotating slide cores support high-volume two-color molding without enlarging the mold.
- Thermoplastic Welded Joint Characterization with Fluorescent Visualization
Fluorescent agents make welded boundaries visible under light, supporting qualitative and quantitative assessment of thermoplastic joints.
- Blow Molding Preform Thermal Imaging to Reduce Blowouts
This case uses infrared imaging and feedback to adjust preform heating, preserving continuous blow molding while reducing blowouts.
- Closed-Loop Oven Heating for Blow Molding Temperature Control
A closed-loop oven measures preform temperatures along and around each preform, then adjusts heating to limit blowouts.
- Hybrid Molded-Pultruded Structural Members for Lightweight Vehicle Support
This case combines dissimilar pultruded and molded materials with ribs to deliver customizable structural support at lower vehicle weight.
- Wave-Shaped TPU Golf Ball Mold for Dimple-Safe Gate Placement
Wave-shaped mold layouts place more gates while protecting golf ball dimples.
- Golf Club Head Ceramic Hosel Insert for Center-of-Gravity Alignment
This case uses a low-density ceramic insert in the hosel to shift the center of gravity and improve off-center forgiveness.
- Blow Molding Split Mold Sliding Mechanism to Prevent Gnawing
A harder, detachable sliding member enables perpendicular mold movement while protecting split-mold boundaries from wear.
- Mold Unit with Protrusion Crushing to Prevent Recessed Defects
Preformed protrusions are crushed during blow molding to prevent recessed defects.
- Aeronautical Engine Thermoplastic Skin Lay-Up for Crystallinity Control
A depositing tool combines pressure, heating, and cooling during lay-up to control crystallinity, adhesion, cost, and cycle time.
- Laser-Patterned Polymer Vehicle Components Without Paint Layers
This case uses laser-sensitive pigments in polymer components to create stone-like surfaces while improving recyclability.
- Vapour Provision Component Boundary Wall for Rigid Aperture Control
Adjacent rigid bodies keep fluid apertures consistent, limiting leakage and protecting aerosol quality in vapour provision systems.
