Forestry TRIZ Cases
- Small Diameter Stainless Steel Maple Spile with Dual O-Rings
Dual o-rings on a small diameter stainless steel spile prevent leaks and improve visibility while minimizing tree wound size.
- Timber-Working Device Hazard Zone Control via Orientation Sensors
Orientation sensors monitor timber-working head angles to preemptively disable chainsaws when operators enter hazard zones, preventing chain shot injuries.
- Maple Tap Sleeve for Sap Yield and Bacterial Control
Disposable inner liner prevents bacterial buildup in reusable taps, increasing sap yield through reduced flow resistance.
- Stump Grinder Spindle Confinement via Boom Opening
A stump grinder spindle rotates freely within a boom opening to accommodate eccentric motion without constant bearing contact.
- Delimb Arm Cam Stop for Variable Closure
Cam stops constrain independent delimb arm movement to accommodate tree sweep while preventing contact with length-measurement wheels.
- Adsorber Support for Oleoresin Exudation
Porous clay carriers holding citric acid increase oleoresin yield threefold while preventing tree degradation and environmental harm.
- Sap Lifter Vacuum System for Maple Collection
Segmented lifters with sealed connections prevent vacuum leaks and venturi-induced icing in uphill maple sap collection networks.
- Flexible Sap Spout with Slide Clamp for Secure Tubing Connection
A flexible sap spout uses a slide clamp to constrict tubing ends, creating a secure frictional connection.
- Rotating Disc Assembly With Multi-Directional Cutting Bits
Multi-directional cutting bits and shock-absorbing shields resolve the trade-off between cutting access and bit durability in stump grinders.
