Bows/Crossbows TRIZ Cases

Segmented contact points distribute pressure along the limb curvature to prevent distortion and slipping during compression of preloaded past parallel limbs.

Rotating spool moves trigger latch via tensile member to disengage string catch, preventing dry fire damage during de-cocking.

An inclined plane hook stop prevents accidental withdrawal, replacing electrical locking systems prone to failure.

Pulley blocks mounted on a sliding carriage multiply pulling force by two to four times, reducing manual effort and preventing finger injury during operation.

Four pulleys synchronize cam rotation and increase cable payout, resolving limited limb travel in traditional designs.

A crossbow trigger latch holds the reciprocating subassembly in place without rope tension.

Elongated crossbow sighter projects a laser beam along the groove axis, eliminating trial bolt firings and reducing calibration time.

A compound bow cam module adjusts draw length via a movable fixing unit and compensating projection.

Independent dual limb adjustments correct cam lean to reduce string wear and improve arrow launch performance.

A bowfishing reel lever locks open to free the line during arrow flight then engages a pinch roller against a reel wheel to retrieve the line.

Stationary axis pulleys allow cams to rotate beyond 270 degrees, resolving the trade-off between extended power stroke and compact bow size.

An integrated winch system lifts weapons via a reel and tightening bolt, allowing hunters to use both hands for climbing safety.

A single mainframe barrel merges AR butt stock mounting with crossbow extrusion features for direct assembly.

Stacked bowl-shaped parts holding granular solid material absorb low-frequency vibrations while maintaining aiming stability.

A rotary cam release mechanism prevents dry-fire accidents by engaging an arrow shaft to block the cam pivot, ensuring safe trigger actuation.

Pneumatic cylinders and worm gears amplify limb draw force, reducing assembly weight and noise for hunters with limited strength.

A pivotable limb mounting system allows bow limbs to flex naturally during drawing.

Dual ratchet pawls prevent catastrophic failure while a silent ratchet eliminates noise that scares game.

Segmented grip adapters customize contact surfaces to reduce recoil and improve accuracy across user sizes.

A fluid-filled tubular device mounted to a bow sight indicates target distance by correlating fluid levels with known ranges.

Segmented elastomeric ribs with irregular profiles dampen high and low frequencies, resolving wide-spectrum vibration issues in archery bows.

Contact pins and indicators on pulley assemblies verify identical cam rotation angles, resolving measurement difficulties during cable length adjustments.

Circular bowstring tracks maintain constant moment arms to eliminate timing errors between rotating limbs for smoother draw.

UV-blocking sheaths protect elastic bow strings from degradation while internal LEDs provide illumination without harmful wavelengths.

A pendulum bow sight uses a pivoting lens assembly to maintain alignment regardless of elevation angle.

A guided clamp and rolling jig attach fletched tape to arrow shafts, resolving the contradiction between manual ease of operation and manufacturing precision.

Threaded rod mechanism shifts internal weight position for on-the-fly balance tuning, resolving fixed stabilizer limitations.

Adjustable bowstring release mechanism with pivotally connected jaws and trigger section for precise retention control.

A crossbow cocking device with retractable Allen wrenches stored in the handles.

Collapsible limbs and an electrical energizer reduce arm fatigue by lowering cocking force while maintaining structural integrity.

Optical fiber transmits ambient light to a lens with alignment indicia, resolving body orientation measurement precision issues.

A cord engager moves between inward and outward positions to manage the bow cable.

Universal receiving sections accept interchangeable adapters to resolve the trade-off between connection versatility and device complexity.

A pivoting arrow rest retracts into a bow riser via spring bias to shield the mechanism from external impacts.

A coupler links an archery bow to a firearm shooting support via a pivot linkage and actuator lever.

Offset cable anchors on rotatable members enable self-alignment, reducing vibration and friction while maintaining arrow launch speed.

An archery bow riser block with multiple offset mounting holes allows precise elevation angle adjustments for varying archer heights.
