Straightedges TRIZ Cases

Linked T-shaped templates pivot to lay out straight or curved seat rows with consistent fastening-point alignment and fewer installation errors.

Dynamic slot allocation and local ID matching let multiple styluses communicate with a sensor controller faster with lower uplink overhead.

Eccentric pins and magnetic blade retention let a combination square be squared faster while maintaining accurate head-to-blade angles.

Slot-based communication lets the sensor controller assign stylus transmission intervals below a frame, reducing uplink size and power use.

Telescopic side bodies and hinged sliding members adapt the ruler to complex stair contours, improving cutting precision and storage.

A star-shaped aperture merges locking functions into one part, reducing manufacturing complexity while maintaining adjustable angle precision.

A stepwise adjustable square with a blade rotating up to 270 degrees relative to the stock.

A two-part angle measurement tool integrates a laser projector to determine and project angles in one continuous operation.

A slidable writing guide with transverse edges constrains pen movement to produce straight, evenly spaced lines on paper.

Rotatable transparent blades with linear slits capture spatial relationships, eliminating iterative guessing errors in perspective drawing.

A combination square uses a spring-loaded dovetail detent to lock the blade position relative to the body.

A self-extending measuring device uses resilient convex members housed in a flexible sleeve to automatically deploy and collapse.

A tool with a leg and recessed support engages irregular workpiece surfaces to maintain precise alignment during customizing operations.

An integrated encoder and display on a sliding T-bevel provide direct numerical angle readouts, eliminating the need for separate protractors.

Segmented base design extends beyond corner radius to resolve measurement accuracy versus device complexity trade-offs.

Segmented finger guard protects hands from knife jumps while leaving the lower blade exposed for foot stabilization and indicia visibility.

A footer square apparatus uses guide lines and angle markings to align strings for precise foundation corner positioning.

A measuring device integrates an ergonomic module with a thumb depression for handling.

An adjustable square combines indexing plates with a friction clutch to resolve the trade-off between fixed precision and arbitrary versatility.

An insert member positions an LED opposite the vial to resolve low-light visibility issues while maintaining compact device complexity.

A magnetic device secures reference tools to metal workpieces, eliminating the need for extra personnel during construction.

Segmenting the level vial into a blade viewing notch resolves poor visibility caused by thick heels, enabling easy bubble confirmation without side viewing.

Integrated transparent ruler with pre-configured apertures reduces manual measurement time while maintaining high drawing precision.

A composite I-beam level adds a plastic insert to an aluminum extrusion, preventing twist and bend under impact.

Multiple angled reference faces around one spirit vial enable multi-angle measurement without increasing device volume.

A speed square features a hinged extension element that continues measurement markings along the tool edge.

A multi-function level integrates deburring and chamfering tools directly into its web structure for precise orientation indication.

A multi-planar measurement kit captures physical evidence in x and y planes without moving elements.
