No-Tie Lace System Design Proposal

CONFIDENTIAL DOCUMENT | Ryan McMahon | (971) 219-5555 | [email protected] | ryanmcmahon.org

Needs Addressed

•  Laces hard to tie when under high tension

•  Difficult to get correct lace tension

•  Cold hands make tying even harder

•  Frequent adjustment not practical with tied laces – especially when using double-knots CONFIDENTIAL DOCUMENT | Ryan McMahon | (971) 219-5555 | [email protected] | ryanmcmahon.org

System Description

Left lace in bottom groove

Right lace in top groove

Laces slide freely in one direction and lock in groove when released


Usage

•  Start day—loose laces for increased comfort

•  Top of run—tighten laces to optimum riding tension (with gloves on!)

•  When needed—release laces and adjust tension

•  Bottom of run—loosen laces for chair ride or hiking


Component Design


Robust Design

•  Intuitive design

•  Easy to use

•  Laces pull in opposing directions in equal force to minimize stress placed on joint between component and boot tongue


Intellectual Property

•  Apply proven sailing technology to apparel

•  Unique design—different from other patents –  Simple design, fewer parts –  Multiple mfg and assy options

•  Related patents –  Lace system for footwear, Burton, #7392602 –  Locking system for elastic laces, #5029371 –  Lace fastening cleat and shoe, #5333398 –  Laced garment closure (not issued)


Competition

•  Burton has 9 models with patented cable and cleat system

•  Salomon has cable cleat system •  Vans has cable cleat system •  K2 has ‘speedlace’ system


Low Risk enhancement

•  No impact on core sole and boot construction or assembly

•  Low cost component and assembly costs

•  Customer can still tie laces if preferred


Mfg & Assy Options

•  Molded plastic component – Rivet to boot tongue – Sew to boot tongue – Glue to boot tongue

•  Molded into boot tongue


Estimates mfg & assy Costs

•  Component costs – No Tie Lace Component (2x) ~ $0.50 – Rivets (4x) ~ $0.04

•  Labor time < 60 sec

•  Est. incremental costs <$1.00 (per pair of boots)
