Lids TRIZ Cases

Torque springs bias the buckle and connector to secure the closure while simplifying assembly.

Segmentation and merging principles simplify manufacturing while maintaining child-resistant functionality through simultaneous actuator depression.

Segmented side panels feature disruption-formed access flaps that provide lateral entry points, resolving finger-insertion bottlenecks in enclosed cartons.

Extending a desiccant insert beyond the container wall increases moisture absorption capacity while eliminating ingestion hazards from loose bags.

A moisture tight container uses an integrated desiccant insert and dual seal system to preserve sensitive products.

A hinge segment integrates a security tab that engages a container shoulder undercut to secure the lid pivotably.

A storage container door lid uses a detachable coupling portion to rotate and open a take-out port from multiple directions.

A lid uses a spring mechanism to push an activator lever that lifts a flow stopper.

Tapered V-shaped grooves reinforce thin-walled plastic food containers, reducing manufacturing complexity while maintaining product visibility.

A paperboard tray assembly uses upper and lower hinge portions to transition between closed and open configurations.

A pivotable cover section engages an aperture via a projection to secure the wiper blade within the receiving channel.

An asymmetric lid design reduces bulk and manufacturing costs while maintaining child-resistant security through a resilient member engaging an abutment.

Parallel passageways straighten rising air flow, forcing water-laden air into an absorbent pad via inertia to prevent condensation on hot food.

Fracturable elements with non-uniform breaking resistance allow easy one-handed opening while maintaining a hermetic seal.

A plastic container hinge uses a tangent pivot line and asymmetric flange extension to create a smooth, uninterrupted perimeter when closed.

A display packaging box uses a tear-openable front plate to reveal stacked product packages while maintaining structural integrity.

Weakened portions on the puller create irreversible curvature upon lifting, resolving the trade-off between secure sealing and tamper detection.

Modular harvesting equipment associates motion-triggered images with GPS timestamps to secure origin certification and reduce fraud.

Flexible elastomeric lip seals single multifunctional opening, preventing gas exchange and leakage in reclosable beverage containers.

Segmented lid parts and vertical side extensions resolve the contradiction between low manufacturing cost and high structural durability.

An elastic middle ring deforms under a press block to disengage from the bottle interface, preventing leakage caused by loose caps during transport.
