Elevators presentation (altacit template)

  1. 1. A Brief Exposé on Elevators <ul><li>An oft neglected requirement of our modern society, the elevator gives structure for our modern urban pursuits and represents a technological leap forward for vertical transportation. </li></ul>
  2. 2. History of the elevator <ul><li>Early BC origins of elevator systems </li></ul><ul><li>Hydraulic elevators were popular in the mid-1800s and are still the norm for low-rise buildings; problematically, they require hydraulic oil and are inefficient </li></ul><ul><li>“ Standing rope control” for elevators invented in 1850 </li></ul><ul><li>Credit goes to Elisha Otis for having invented the first safety passenger (brake) elevator in 1852 </li></ul><ul><ul><li>This elevator featured a lock-spring which would engage should the elevator descend too quickly ie if the cable were to break </li></ul></ul>
  3. 3. (Cont) <ul><li>1857: Otis showcases the first passenger elevator (for a department store) </li></ul><ul><li>1874: JW Meaker patents safety method for elevator doors </li></ul><ul><li>1880: World’s first electric elevator </li></ul><ul><li>1889: Direct-connected geared electric elevator </li></ul><ul><li>1903: Gearless traction elevator </li></ul><ul><li>1940’s: push-button elevators (not requiring human dispatchers) </li></ul><ul><li>1950’s: pre-programmed elevators responding to peak hours </li></ul><ul><li>1960’s: introduction of microcomputers to create a more efficient elevator </li></ul><ul><li>1996: Machine room-less elevators by Kone save space and energy (1/3 the energy use of hydraulic elevators) </li></ul>
  4. 4. Patent information: total US patents granted <ul><li>Elevator – 24,800 hits </li></ul><ul><li>A refined inspection of the patents reveals that 2796 (approx.) have been filed in the US which are pertinent to elevator technology </li></ul><ul><ul><li>Includes inventive steps to elevator systems, safety features, physical design, electronic monitoring, control systems and ancillary features </li></ul></ul><ul><ul><li>374 patents for induction motors </li></ul></ul><ul><ul><li>13 patents for machine room-less </li></ul></ul>
  5. 5. Major patent-holders <ul><li>1139 </li></ul><ul><li>42 (with Westinghouse, 289) </li></ul><ul><li>Inventio – 350 </li></ul><ul><li>31 </li></ul><ul><li>164 </li></ul><ul><li>72 </li></ul><ul><li>51 </li></ul><ul><li>2 (American office) </li></ul>
  6. 6. Examples of Patents and *Published Applications Serial Number Invention Title Serial Number Invention Title 1 (2010) Elevator 6 (1980) Floor selector system for elevator 2 (2005) Elevator System *7 Method for determining replacement state of wear of elevator means 3 (2003) Elevator belt assembly with noise reducing groove arrangement *8 Elevator system (speed) 4 (2000) Interactive elevator communication system *9 Elevator guide-rail system 5 (2002) Method for preventing an inadmissibly high speed of the load *10 Security-based elevator control
  7. 8. Patents observed in situ Earthquake-setting control system Machine room-less elevator Elevator system Gap-sealing technology Elevator group control system Safety equipment for preventing an elevator car collision with an object Method for preventing unnatural high-speed Interactive elevator communication system
  8. 9. Notable patent infringement cases <ul><li>Schindler v Otis (2010) – for an elevator feature capable of recognizing a user upon walking into a monitored area and sending an elevator to bring the user to the relevant floor, no infringement was found. </li></ul><ul><li>Kone v Zheijiang (China) – elevator driving device attached to the wall instead of the ceiling was found to infringe under the “doctrine of equivalents”. </li></ul>
  9. 10. (cont) <ul><li>Inventio AG v ThyssenKrupp – defendant prevails in this suit alleging infringement for temporary overlay patent providing controls with dispatch functionality; plaintiff’s patents revoked. </li></ul><ul><li>Advanced Hydraulics v Otis – “hydraulic elevator” patent of 1951 assigned to plaintiff and was likely infringed; however, estoppel due to delay and laches prohibited the claim </li></ul><ul><li>Kone v ThyssenKrupp (2009) – pending suit </li></ul>
  10. 11. Future of the industry <ul><li>Looking at environmentally-friendly technology and efficient use of shaft space </li></ul><ul><li>Passenger comfort and smarter technologies to recognize passengers for security purposes, with emphasized research into computerized innovations </li></ul><ul><li>Economic downturn has been reducing sales and stymied high-rise development </li></ul><ul><ul><li>Replacements for outdated and irreparable elevator systems less in demand than previously predicted </li></ul></ul><ul><li>Competitiveness of the field set to increase following the immense fines (nearly $1 billion USD) levied against the largest elevator companies by the EU Competition Commission for price fixing and illicit collusion </li></ul>
  11. 12. Bizarre and logical tech improvements <ul><li>“ Vacuum” elevators of science fiction, using air pressure to transport tenants and workers </li></ul><ul><li>“ Smell sensors” to determine whether or not the tenant is actually whom he presents himself to be </li></ul><ul><li>Magnetic suspension system – Mitsubishi – in trial stage </li></ul><ul><li>More efficient hydraulic systems for cities with blackouts and electrical precariousness </li></ul>
