Doors/Windows TRIZ Cases

A segmented sash guide assembly enables smooth vertical movement of the window sash within the jamb channel.

Adjustable jaw spacing eliminates tool changes, enabling high-rate production of frames with consistent corner thickness.

A double-glazing panel uses transparent plastic profiles glued to glass sheets via methacrylic urethane adhesive.

Powered vehicle doors use sensor feedback to prevent collisions with obstacles, enhancing safety while maintaining a simple handle-less design.

A single central catch slows door motion while a self-attaching mounting arm eliminates discrete fasteners, reducing design complexity.

An integrated elastic seal replaces adhesive injection in corner joints, eliminating material waste and contamination risks while ensuring uniform sealing.

Metal reinforcement embedded in a polymer spacer matches glass thermal expansion while the barrier film ensures moisture tightness, preventing fogging.

A chromium steel connector joins a silver conductive track using a tin-silver-copper solder alloy.

A concealed drive device for sliding leaves uses spring-loaded adapter elements to vertically adjust the motor housing relative to the guide rail.

A polymeric spacer incorporates embedded metal reinforcement strips to provide structural stability and bendability without acting as a thermal bridge.

Segmenting the rebate area hides hardware elements that compromise aesthetics, while protruding webs reinforce rigidity and reduce air gap height.

A plug-in connector uses diagonal elastic stop elements to yield during insertion, maintaining alignment of hollow profiled spacer frames.
