Finger Joining Apparatus TRIZ Cases
- Finger-Jointed Workpieces With Transverse Grooves for Crack Reduction
Transverse grooves in hardwood finger joints improve adhesive filling and stress distribution, increasing tensile and bending strength while reducing cracking.
- Angled Finger Joint Geometry for Wood Strength
Oblique finger joint geometry expands contact surface area to boost bending strength without adding manufacturing complexity.
