Sheet Joining TRIZ Cases

A sole recess and movable keel surface let players tune resting face angle to improve ball flight consistency and reduce hooks or slices.

A two-part fastener drives fixing arms into the sandwich core to create a robust frictional joint without adhesive bond weakness.

A deformed aluminum filler with dispersoids enables solid-state extrusion bonding that avoids hot cracking, pores, and wide heat-affected zones.

A heated mandrel expands pre-drilled bores in thermoplastic aircraft composites to fit rivets, reducing fiber damage and crack propagation.

Secondary definitive connections hold parts aligned while main holes are drilled and joined in one step, cutting assembly time and re-machining.

Built-in sensing and wireless transmission let the locking bolt report axial position, avoiding complex external checks and insecure fastening.

Shifted contact points and a Z-shaped opening let sheet metal parts align accurately despite shape variation, without enlarging the parts.

A deformable straight tongue enables compact vertical locking in 3-5 mm floor panels while lowering production cost and preserving joint strength.

Flexible receiver and coupling plate features keep coupling forces repeatable while reducing panel-to-support clearance in automotive fasteners.

A vertical seam profile seals adjacent elevator wall panels to block noise and dust while improving fire resistance and installation.

S-shaped connector shock absorbers between the shell and crown strap absorb impact energy and reduce force transferred to the wearer's head.

A nested coupler and shock absorber let a helmet harness absorb rotational forces while preserving alignment and six-degree movement.

Local heating lets thermoplastic flow into a hollow metal fastener, creating a reliable composite-to-metal joint after cooling.

A rotating locking hook presses clipped spoiler parts together to remove gaps, improve flushness, and keep fixation secure.

Fiber wraps in side grooves and resin transfer molding secure a saddle lug to a composite tube without drilling, preserving strength and load transfer.

Controlled Sn-Ag-Cu-Sb-Ni solder layers preserve the Ni back metal, reduce separation and non-wetting, and improve chip heat dissipation.

A rotatable arc adjuster and locking rod simplify arc lock maintenance while enabling precise multi-position angle setting.

Wedge guides and expansion wedges turn axial fastener force into radial clamping, creating rigid joints without distortion, slip, or rework.

A threaded reusable locking element lets overlapping tiles be tightened, removed cleanly, and adapted to varying flange heights.

Elastic wall sections let a ceiling double hook detach at a defined tensile load, protecting clips and substructure from costly damage.

A wedge-lock female and male connector enables tool-free furniture assembly while resisting pull-apart forces through elastic snap-fit retention.

Controlled Mn, Ti, and Nb composition refines the weld HAZ in 900 MPa steel sheets to prevent interface fracture and preserve cross-tensile strength.

Reinforcing ribs and matched wall depressions improve transverse strength while allowing adjustable, secure mounting in thin-wall rectangular holes.

Mechanical vibration liquefies a thermoplastic connector to pierce thin layers and lock into lightweight sandwich boards with stable anchoring.

A hanger-rod locking structure lets one worker align and secure adjacent LED modules quickly while improving joint stability and stress distribution.
