Orthogonal upper and lower brackets let a crib mobile shift vertically and sideways for adjustment, emergency access, and disinfection without loose parts.

A modular container uses an inner bin, label-retaining cover, and airflow lid to save space, separate old and new products, and keep food fresh.

A pivoting crib mobile arm folds into a recessed sidewall or leg to stay attached, reduce detachment risk, and simplify storage.

A modified triangular inflatable support cuts plastic use and inflation time while improving infant lateral support and frame-based stimulation.

Interlocking tongue-and-groove housings let solar-powered decorative units join into flexible display combinations without complex assembly.

Removable canopy panels deliver age-appropriate visual stimulation across child carriers while preserving shade and weather protection.

A tuned silicone elastomer balances stain resistance with skin-like flexibility and touch by controlling loss tangent and hardness.

A fabric-covered embedded track and sliding clip secure toys on a pillow while avoiding zipper-like edges that can cut or scrape infant skin.

Dedicated label pockets, sub-containers, and lid stand-offs improve pantry space use while keeping product info accessible and food fresher.

A backlash-tolerant disc coupling isolates encoder sensing from asymmetric loads, improving rotational position accuracy in modular motor units.

A backlash-tolerant encoder coupling isolates asymmetric load effects, preserving precise rotational position sensing in modular motor units.

Distributed rotary coupling points with convex-concave fits cut assembly time and enable tool-free shape-changing rigid member structures.

Convex-concave multi-point joints replace central shaft insertion, speeding assembly of rotatable rigid members for extendable 3D structures.

A plastic expansion-clamp plug locks into a wood block socket to replace adhesives with durable, detachable joints that simplify recycling.

Cam-based locking replaces threads in a modular joint assembly, enabling tool-less structural connections and integrated paths for power, water, or data.

Standard square-tube blocks and unified fasteners create rigid or movable corner joints from 0° to 180° while keeping structures strong.

A rivet and insertion tool align pre-punched paper holes to create a secure permanent joint without glue, staples, or tape.

Standardized square-tube blocks and auxiliary pivot parts create rigid or movable corner joints from 0° to 180° for strong, flexible assemblies.

Hinged wall panels and a self-expanding gable roof let the playhouse fold flat for shipping while reducing assembly time and loose parts.

Retained fasteners and hinged accordion panels cut setup time and storage bulk while keeping the play structure secure and decorative.

Guide grooves and an elastic recessed joint let straight assembly blocks self-align, couple easily, and resist wear through repeated use.

Male and female interlocking members plus three-axis bore holes secure toy block creations to walls while preventing movement and breakage.

A snap-fit rivet and guide tool secure paper through aligned holes, improving fastening accuracy without glue, tape, or staples.

Segmented plate-like pieces with integral bendable connectors and coupling portions form flexible sheet structures such as bags.

Conic bead-and-groove joints keep blocks secure during play, then release smoothly by twisting to reduce separation force for children.

Retained fasteners in corner hinges let accordion-fold panels unfold and lock quickly, reducing storage space and one-person assembly effort.

A keyed insert spreads mating engagement portions to create strong, easy-to-install joints that resist compression and rotational loads.

An accordion-fold panel structure cuts playhouse assembly time while shrinking shipping and storage volume without losing roof and shelf features.

A central pivot with sliding bushings and integrated locking lets modular bars form rigid 3D structures that collapse without disconnecting.

A central-pivot joint lets orthogonal bars rotate and lock, so 3D modular frames assemble fast and collapse into one plane without disconnection.

Embedded metallic foil and a coil sensor grid identify the open page and page-turn motion without bulky hinges, cameras, or rigid page holes.

Conductive snap-together blocks replace tangled wires, making circuit paths visible and enabling triggerable actions without separate data lines.
