1.2Methodical Design: The Wright Brothers’ Success in Manned Flight – Lift, Control, Power, questions
1.3Nth Generation Design: Refining the Typewriter – QWERTY, why still use it
1.4Single Use Cameras – redesigned for Japan, Germany, other
Chapter 2
Establishing need, (Safety and quality of life, Improve existing product or system, commercial incentives, personal experiences, opportunities from scientific advancements), Service to Humanity, Types of problems: prediction, explanation, invention, Focusing upon others: A key to Success, The design proposal.

2.9Bhopal: Simultaneous Failures Lead to Disaster
2.10Rushing to Fill the Teton Dam Leads to Its Collapse
Chapter 3:
Structuring the Search for the Problem. Focus on function, Formulating the real problem, techniques---statement-restatement, determine the source and cause, revision method, PS-DS, Duncker diagrams, K-T situation analysis, K-T problem analysis
3.1The Tylenol Case – problem is to prevent tampering with capsules, not bottles, new type using solid
3.2Blowing in the Wind: Boston’s JohnHancockTower – note K-T analysis, solder/reflective coating, too flexible on long edge, wind added
3.3Apollo 13: Preventing a Tragedy – ground crew connected heater to wrong power supply
Chapter 4:
Structuring the search for solutions. Eliminate impossible paths, extract useful information, evaluate final solution state. General goals: safety, environmental protection, public acceptance, reliability, performance, ease of operation, durability, min maintenance, std parts, min cost. Ergonomics.
4.1Improper Waste Disposal at LoveCanal and TimesBeach – missed goal of safe efficient disposal
4.2The Collapse of the Baldwin Dam – design error, invalid assumptions, missed secondary effects and activities that interacted with system
4.3Perrier Water – not concerned with public perception, when product was faulty
4.4The Pentium Computer Chip – must retain public’s trust and confidence
4.5Two Routes to Simplicity: Camcorder Redesigns – two companies made products easier to use, response, even if lost some capabilities
4.6O-Rings and the Challenger Disaster – design flaw, engineers need to understand interactions of components and system, plus unwillingness to be the scapegoat, manufacturing tolerances of parts
4.7Fax Machines – reduction in price, improved performance, becomes popular
4.8The Development of Band-Aids – cotton buyer, personal needs, goals
4.9The Ergonomically Designed Lounge Chair – look at functions needed
