Conveying Record Carriers TRIZ Cases

Movable contact part electrically couples to chassis ground, enhancing electromagnetic compatibility and shock resistance for storage system plug-in cards.

A processing unit dynamically switches stepper motor step driving modes based on available computing power.

A locking connector uses a fixed elastic arm to maintain stable electrical contact between a card and circuit board.

Capacitance sensor detects skimming devices in card passage, preventing unauthorized magnetic data access.

Segmented cleaning elements on a handled substrate remove contaminants from rollers and sensors, reducing manual labor time.

A card reader insertion part uses a flexible wiring member to connect a ground pattern to the main body for static discharge.

A resilient element moves a door relative to a tray, solving accessibility issues caused by rear-mounted battery designs.

Stationary magazines flank a clocked conveyor belt, allowing sequential feeding of varied card types without mechanical repositioning or cycle time penalties.

Cover members seal optical sensors to prevent dust accumulation on detection elements.

Foot and protrusions on the card reader body prevent accidental button presses while the face plate stops rotation.

Color-coded slots and asymmetric flanges resolve rotation issues in compact mobile card readers.

A card handling device uses a movable floor member to slide cards via gravity.

Inclined deformation-suppressing portions on the card holder frame prevent contact damage during insertion and extraction cycles.

Transverse flock strips on a PVC substrate absorb contaminants without redistribution, preventing machine failures in card readers.

An obliquely angled card receptacle directs liquid away from the reading and writing device to prevent ingress.
