【摘要】：以智能手机、平板电脑为代表的移动通信终端，带给使用者沟通和获取信息方式的深刻变革。现有的移动通信终端产品，普遍采用内置锂电池供电。由于锂电池能量密度有限，以及功耗日益提升，移动终端设备待机/使用时间往往不尽人意，，需要频繁使用外置电源进行电能补充。除了作为移动设备标准附件的充电器，现有的移动终端外置电源解决方案，还有备用电池、充电底座、无线充电、移动电源等产品。本文在简要介绍上述解决方案的技术原理，发展沿革，未来趋势的基础上，引入需求与效用概念，根据用户使用行为习惯，将移动终端产品使用情境细分为基础情境、桌面情境和户外情境；对于移动终端使用时间的需求，以及各类移动终端外置电源解决方案满足上述需求所应具备的客观效用，进行定义与需求层次划分；并拓展出安全性、易获得性和可选择性、充电速率、容量、操作便捷性、文化传承等效用内涵与外延。而后，运用基数效用理论和序数效用理论，对不同使用情境下典型的移动终端外置电源解决方案进行效用评价。在效用评价的基础上，运用价值工程基本原理和工具，瞄准无线充电解决方案的性价比不足，以其便捷使用体验为目标，以充电底座为蓝本，开发一种低成本的“无绳”充电解决方案。
[Abstract]:Mobile communication terminals, represented by smart phones and tablets, bring profound changes in the way users communicate and obtain information. The existing mobile communication terminal products, generally use built-in lithium battery power supply. Due to the limited energy density of lithium batteries and the increasing power consumption, the standby / service time of mobile terminal equipment is often unsatisfactory, which requires frequent use of external power supply for power replenishment. In addition to chargers as standard accessories for mobile devices, the existing mobile terminal external power solutions, as well as spare batteries, charging base, wireless charging, mobile power supply and other products. On the basis of brief introduction of the technical principle, development history and future trend of the above solutions, this paper introduces the concepts of demand and utility, and subdivides the usage situation of mobile terminal products into basic situations according to the user's behavior habits. Desktop and outdoor situations; For the need of mobile terminal service time and the objective utility that all kinds of mobile terminal external power solutions should have to meet the above requirements, the definition and requirement level division are carried out. The utility connotation and extension of security, accessibility and selectivity, charge rate, capacity, operation convenience, cultural heritage and so on are developed. Then, the utility evaluation of the typical mobile terminal external power supply solutions under different usage situations is carried out by using the cardinality utility theory and ordinal utility theory. On the basis of utility evaluation, applying the basic principles and tools of value engineering, aiming at the lack of performance-price ratio of wireless charging solution, aiming at its convenient use experience, taking the charging base as its blueprint, Develop a low-cost "cordless" charging solution.
