时装秀场在建筑学角度，是一种时间与空间密集相互感知的四维设计。好似飞行建筑事务所第三次为YINGPEI STUDIO设计的秀场，进化为一场经过计算的极简短剧，分为五段式。

From the perspective of architecture, fashion show is a four-dimensional design that time and space interact closely. The third time House Fiction designed fashion show for YINGPEI STUDIO, has evolved into a minimal drama with physical calculation. It was divided into five stages.

底座是个充满机关的大黑匣子，8米长的指针支在其1/4处，初始状态向入场观众展现通过电机维持着的平衡假象。

The base of the installation was a big black box with mechanism. The 8-meter-long needle was supported by the box at a quarter of its length . The initial state showed the audience the illusion of balance maintained by the motor.

悬挑6米的细长直线杆，需避免过大悬挑杆端的重力变形。为确定细长悬挑杆的变形状态，采用SAP2000有限元计算分析软件对截面为P60x1.5的钢管变形予以分析，结果表明钢管因材质密度大导致悬挑杆端的挠度变形过于明显，而不满足外观设计要求。为实现长悬挑细长杆较理想的直线外观，改为采用弹性模量与钢材接近，但密度仅是钢材的1/5，强度是钢材10倍的航空器材用碳纤维管，经计算同截面的碳纤维管悬挑端的挠度变形明显小于钢管，其自重变形后的外观可以接受。单根8米长的杆造价超支，故采用4根2米长的现成品用套管连接。装置体量结合所处空间尺寸、模特高度、观众视线和其自身的部件对比达到最优表现。

It was necessary to avoid deformation at the end of the 6-meter cantiliver rod (referred to needle).  In order to determine the deformation degree of the rod, the SAP2000 software was used to analyse the deformation of the steel rod with a cross-section of P60x1.5. The results showed that its high density caused thedeformation of the deflection at the end of the rod to be too obvious (see the first row of the diagram below),which did not meet the design requirements. In order to achieve the ideal linear appearance of the rod, carbon fiber rod was chosen because it used for aviation equipment with elastic modulus close to steel but its density is only 1/5 of steel, and the strength is 10 times that of it. After calculation, the deformation of the deflection at the end of the carbon fiber rod with the same cross-section is significantly smaller than that of the steel one (see the second row of the diagram below), which was acceptable on the appearance. The cost of an single 8-meter-long rod exceeded the budget, so four 2-meter-long ready-made rods connected by jacket tube became the solution. The volume of the installation achieved the best performance based on the space size, the height of the model, the line of sight of the audience and the comparison of its own components.

全场暗下来，走秀音乐起，灯光随着第一个模特出场的脚步渐亮，至形成一个C型秀道。指针被模特开启旋转，或说引领着模特，随分秒流逝在圆形空间中环绕。 一线带两点的运动便撑起直径28米的油罐空间。圆中心的黑匣子隐匿于黑暗中，光线随针头流动。人们在十多分钟内将对这平淡的重复转动习以为常。
