Personalization for Massive Product Innovation Using Open Architecture

Product innovation is creation of new concepts to plan and realize technological and functional details in the product to satisfy market and customer needs. One of the key drivers to product innovation is reactions of the product to users’ needs. Product innovation needs a cognitive design method based on needs of variant users for the product personalization. In this paper, an open concept is introduced to provide ways to meet user’s individual need in product lifespan. It is for industries to propose product concepts based on open sources, develop and support the product on the public capability. Using the open concept in the product architecture, called open?architecture product(OAP), can improve the product personalization leading to massive product innovation. To promote this promise of the OAP, effective methods are discussed for the OAP development. This paper introduces research on OAPs using adaptable design methods to meet product personalization. Adaptable design is based on the modular structure for product adaptability using function modules and adaptable interfaces. The proposed method provides solutions for planning modules and implementation of OAPs. Methods of OAP module planning, detail and interface design are described for transformation of product concepts into physical structures. A multiple?purpose electrical car is developed in a case study to show effectiveness of the proposed method.

Optimal Design of Bionic Flexible Fixation System for MRI-Guided Breast Biopsy

In Magnetic Resonance Imaging(MRI)guided intervention procedures,the flexibility and reliability of the mammary gland fixation device are important indicators for cnsuring the quality of surgery.This paper presents a bionic flexible fixation system for MRI-guided breast biopsy,and establishes a mathematical model of the palm-type curved plate and a breast compression model.The bending angle,eccentricity,and tightening stroke of the palm-type curved plate are considered the main influencing factors.The bending angle and eccentricity of the bionic palm-type curved plate and flexible fingers are optimized,and a prototype of the breast fixation system is developed.The experimental results show that when the external force is 10 N,the average repetitive accuracy of four lesion points is 0.71 mm,0.60 mm,0.63 mm,and 0.68 mm,respectively.When the pressures are 8 N,10 N,and 12 N,the thickness of the compressed tissue is 76.27 mm,72.8 mm and 68.73 mm,respectively.It has good repetitive accuracy and is compatible with the concept of flexible fixation that reduces the uncomfortable feeling of the human body.We propose that by optimizing the flexible tightening mechanism,it is feasible to properly control the external compression force to effectively reduce the compression pain for patients while guaranteeing the tightening reliability in breast biopsy.
