Bows/Crossbows TRIZ Cases

A compound bow uses a rigid frame with pulleys and cams to store energy efficiently.

Asymmetric cable positioning with offset rollers balances lateral forces on rotatable members, reducing lean and improving crossbow stability.

Rotatable launcher arm moves away from arrow path upon string release, ensuring consistent trajectory across temperature extremes.

Correlated distance markers eliminate electronic complexity by matching pin colors to external targets for accurate range finding.

Asymmetric rail apertures guide accessories into precise orientations while a single wedge fastener secures the component to the bow riser.

An archery trainer uses an elastic member and adjustable weight to simulate bow tension for muscle strengthening.

Elastomeric ring in pulley groove prevents bowstring slippage, improving arrow speed and energy transfer efficiency.

A crossbow track assembly integrates a string dampener with thermoplastic elastomer members to absorb vibration energy.

A bowstring release wrist strap uses a ratcheting spool and cable to cinch securely around the archer's wrist.

Bowstring guides push the string toward barrel sides to resolve reliability and complexity trade-offs.

A projectile launcher encloses vertically spaced bow arms within a protective housing structure.

Segmented bow press connects to pulley axles to manage torsional forces and prevent limb damage during field maintenance.

Servicing cable rotates rotatable members past brace condition to unload tension, eliminating the need for a specialized bow press during maintenance.
