![]() ![]() The problem with this thinking is that we now guarantee risk. The compromise "solution" for the vehicle would be to make the volume larger but not “too large”. This is a standard approach taught in most engineering schools and widely adopted throughout industry for resolving problems of all genre. ![]() For this text, we will not discount either conflicting property as invalid but rather assume that we are only dealing with situations where the requirements for both properties are valid because we have thoroughly analyzed the situation.Ģ) Compromise somewhere between both conflicting properties. As mentioned, this approach is less common in the world of physics, but it can happen in many other fields. In the case of the vehicle we would either deny that the drag existed or we would deny that the volume was too small. Either we do not face the problem or we force someone else to deal with the problem. This approach can be referred to as the "ostrich burying its head" approach or throwing the hand grenade back over the wall. This is a common approach used in theological, political, negotiation or historical settings. There are several approaches to dealing with contradictions:ġ) Discount one or both of the conflicting properties. The knob (volume) must have settings (small and large).Ĭommon Approaches for Dealing with Contradictions This appears to be physically impossible, yet we will try very hard to make this happen. For instance, let us consider a vehicle that needs to have a small volume in order to create low drag and a large volume to carry lots of cargo. To describe the level of the attribute or variable, we will use the word "setting". In this text, we will use the word "knob" extensively to mean variables or attributes. At the heart of most contradictions is attribute or variable that must have two different levels to satisfy all requirements. It allows us to improve offering features without making other features worse. The skill of resolving contradictions is one of the most useful and fundamental aspects of TRIZ because it greatly expands the solution space for the problem solver.
