Hermetically-Sealed Casings TRIZ Cases

A high-aspect-ratio wall isolates welding heat and stress from the partition, preserving the hermetic vacuum seal and extending feedthrough life.

Anti-rotation geometry and sealing elements create a leak-tight high-current box connection that withstands thermal shock and protects the PCB.

A deformed metal panel creates a gasket-free labyrinth seal for converter boxes, blocking liquid and dust while reducing maintenance.

An elastic sealing ring bends under compression to keep lens-to-board spacing stable while blocking debris from the optical path.

An elastic seal with a bending point blocks debris between the lens module and PCB while preserving sensor alignment and image quality.

A flexible shield seals gaps between the wall plate and switch to block liquid ingress while keeping sensor functions usable.

Ultrashort-pulse laser bonding lines help glass enclosures resist shear forces while staying compact and hermetically sealed.

Power use inside a sealed HDD is tracked to infer oxygen depletion and trigger oxygen generation, preserving vibration stability and service life.

A deformation-limiting element and stepped fastener openings let the sealing bead sit closer to passage holes without over-compression.

A bent display panel edge filled and covered by sealant cuts screen border clearance while protecting the bend from force, water, and oil.

A sealed key assembly bonds the PCB between layered plates to block humidity and contamination that can corrode internal electronics.

Side walls and sealing blocks replace module housing and adhesive bonding, simplifying power module assembly while improving heat transfer.

Pressurized insulating liquid cooling and degassing suppress gas bubbles in compact high-voltage pulsed power supplies for plasma processing.

A sleeve, PCB, and potting seal with grooves maintain hermetic electrical isolation under pressure and help contain explosive forces.

A stepped wiper gasket seals the hinge against water and dust while internal mounts divert frame stress to preserve seal integrity and serviceability.

A flow-blocking frame structure redirects injection plastic to prevent sealing-surface overflow, improving bonding and thin-device sealing reliability.

Sealed electronic devices are immersed in coolant inside the housing to improve dense-system cooling without added coolant paths or circuit redesign.

A sealing groove and plate split the sealant path into inner and outer cavities, reducing exterior overflow during inverter assembly.
