摘要
以电吹风出风口原件为载体,提出创新动态设计与智慧制造的新方式。通过对原型进行采集前打磨与修复处理,对原型喷涂显像剂提高对比度,利用三维激光扫描技术采集原型点云,并进行数据修复封装得到STL数据。从已有STL数据基础上还对其进行曲面重构,参考出风口实体,提取STL的参数特征进行曲面重建,特征参数再建立。以已有的电吹风造型为依据,参考三维扫描到的STL数据,创新设计新的电吹风出风口模型。通过3D打印方式对创新的模型进行快速制造,验证新的出风口设计的可行性。动态设计与制造方式能有效解决目前市面上的产品各零件间衔接与功能失衡问题,通过对创新模型进行反复设计与试制,验证其可靠性,选取最优的创新方案,为量产产品迭代提供依据。该创新设计可以达到以数据赋能开发效果。
A new way of innovative dynamic design and intelligent manufacturing was proposed by taking the hair dryer outlet as the carrier.The prototype was polished and repaired before collection,the contrast of the prototype was improved by spraying imaging agent,the prototype point cloud was collected by 3D laser scanning technology,and the data was repaired and encapsulated to obtain STL data.Based on the existing STL data,the surface reconstruction was also carried out,and the parameter characteristics of STL were extracted for surface reconstruction by referring to the outlet entity,and the characteristic parameters were re-established.Based on the existing hairdryer model and STL data obtained from 3D scanning,a new hairdryer outlet model was innovatively designed.The innovative model was quickly manufactured by 3D printing to verify the feasibility of the new outlet design.Dynamic design and manufacturing method could effectively solve the problem of connection and functional imbalance between various parts of products on the market at present.Through repeated design and trial production of the innovation model,its reliability was verified,and the optimal innovation scheme was selected to provide the basis for mass production product iteration.The innovative design can achieve the effect of data enabled development.
