Obstacles constantly come up in the way of comprehensively analyzing design, and various paradoxes may be posed by making research from all angles. New ideas and novel concept descriptions will be presented by different people at different times. But that doesn't affect at all the many possibilities and uncertainties that we know about it as well as its weaknesses. What we do is to correctly convey design information, avoid unnecessary repetition of misunderstanding and waste of resources, establish an effective medium between designers and viewers in terms of visual perception, and conduct effective communication and judgment. Design itself is not a debate, similarly, there is no perfect thing in the world, for everything has its two sides. Design is assigned, possessed, and used by different civilizations. Designers should be confident in that they have the ability of logical analysis and interpretation of real objects, are able to perceive things and phenomena consciously to the greatest extent, shape them intuitively and clearly, and better grasp the evolution of the times.
