傳統的硬碟機固定結構在振動實驗中輸予1G加速度、震幅0.06英吋、掃頻10 HZ∼500HZ，在高頻時加速度放大產生結構疲勞現象而發生傳輸速率驟降，此現象易造成硬碟機壽命降低、資料遺失。本文以此缺點為改善之動機，首先透過品質機能展開與TRIZ三十九工程參數群組所結合的｢群組品質屋｣來獲得首要的欲改善設計目標「硬碟機減振裝置結構」，然後應用具有工程參數分群概念的「改良式TRIZ判讀系統」來選擇欲改善參數「物體的穩定性」，再由該系統提供優先發明法則與不欲惡化參數，透過專業知識來判斷可行的發明法則為「局部或過度的動作」與不欲惡化參數為「力量」，進而提出改善設計方案，其為在硬碟機減振裝置模組固定於系統機殼的四個螺柱上進一步改良具有阻尼材料的減振結構來達到Z軸方向的減振作用。最後進行振動實驗方式來驗證，證明本文提出的硬碟機減振結構改善方案於1G加速度、震幅0.06英吋、掃頻10 HZ∼500HZ的振動實驗架構下，硬碟的傳輸速率比以往的硬碟硬碟減振產品呈現較穩定的狀態，可提升硬碟使用壽命、減少資料遺失。
本文再度以具有品質屋與TRIZ工程參數群組所結合的｢群組品質屋｣來獲得次要的欲改善設計目標「組裝簡易化」，由於在改善硬碟機減振結構之問題時所增加的減振阻尼材於組裝時不甚方便，有組裝困難、製造性不佳之缺點，然後再以「改良式TRIZ判讀系統」來選擇欲改善參數「製造性」再由系統提供的優先發明法則與不欲惡化參數中判斷可行的發明法則為「抽出」與不欲惡化參數為「使用方便性」，進而提出將減振阻尼材由原本不易組裝組裝改由側向組裝，並於側向入口處增加一缺口以改善組裝不易、減少組裝工時浪費。
然而組裝不易之缺點也發生於傳輸線要組裝於硬碟機的時候，由於硬碟減振結構以軟質材料固定，傳輸線組裝時硬碟機減振裝置模組又無施力處供手扶持，傳輸線不易組裝，本文又以「改良式TRIZ判讀系統」來選擇欲改善參數「製造性」再由系統提供的優先發明法則與不欲惡化參數中判斷可行的發明法則為「抽出」與不欲惡化參數為「使用方便性」，進而提出於硬碟機減振裝置模組的上蓋機殼增加缺口，組裝時讓手有扶持空間以改善傳輸線組裝不易之缺點。
經過三次改善以群組品質屋得到欲改善設計目標再經過「改良式TRIZ判讀系統」來獲得欲改善參數、發明法則與不欲惡化參數的創研流程，相較於傳統TRIZ具有降低方向錯誤，達到縮短研發時程的效果。
本研究最後找尋相關的硬碟機減振結構專利文件作比較，相較之下本文所提出的改善方案具有硬碟機減振結構的新穎性以及硬碟機傳輸效率較穩定與組裝簡易的進步性與產業利用性。

When the fixed structure of the traditional hard disk drive is given 1G of acceleration speed, 0.06 inch of vibration amplitude, 10 HZ~500HZ of sweep during vibration experiment, the acceleration speed will increase when in high frequency, causing the fatigue phenomenon of the structure that makes the transmission speed drop suddenly. This phenomenon can easily reduce the longevity of the hard disk drive and cause the missing of information. This study adopts this demerit as the motive of improvement to firstly achieve the primary target of improving the design of the “structure of the vibration reduction device of the hard disk drive” through quality function deployment and “the cluster’s house of quality” that is formed by 39 items of TRIZ engineering parameter clusters. It then applies the “improved TRIZ diagnostic system” having engineering parameter clustering concept to choose the “stability of the object” of the parameters for improvement. By means of the prioritized invention principle and don’t want to worsen the parameter provided by that system, the feasible invention principle is in “partial, overdone or excessive actions” and don’t want to worsen the parameter is the “force” upon the diagnosis of the professional knowledge. Researcher can thereupon propose design project which fixes the vibration reduction device module of the hard disk drive on four studs of the system case. This can improve the vibration reduction structure having damping material to reach the vibration reduction action in the direction of Z axis. Lastly, this paper undergoes vibration experiment to prove that the project of “improving the structure of vibration reduction of the hard disk drive” proposed herein is having a more stable transmission speed than the vibration reduction products of the hard disk drive in the past, enabling an enhanced usage longevity of the hard disk and lowering the possibility of missing information.
This paper once again uses “the cluster’s house of quality” that is combined with the house of quality and TRIZ engineering parameter cluster to achieve the secondary design target of “simplification of assembly.” Bearing the demerits of difficulty in assembly and poor design for manufacture, the additional vibration reduction damping material used for improving the vibration reduction structure of the hard disk drive is not easy to assemble. Therefore, “improved TRIZ diagnostic system” is used to choose the “design for manufacture” of the parameters, and then uses the prioritized invention principle and don’t want to worsen the parameter provided by the system to evaluate that the feasible invention principle is “Extraction” and don’t want to worsen the parameter is “convenience of use.” It then further proposes to change the original assembly of the damping material to that of side assembly and to add a gap in that area, so as to solve the problem of difficulty of assembly and reduce assembly time.
However, the demerit of difficulty of assembly also occurs when attaching the transmission wire to the hard disk drive. Since the vibration reduction structure of the hard disk is fixed by soft material and also, it is not easy to assemble the transmission cable since hand-holding area is unavailable in the vibration reduction device module of the hard disk drive, this paper further uses “improved TRIZ diagnostic system” to choose the "design for manufacture” of the parameters for improvement, and then uses the prioritized invention principle and don’t want to worsen the parameter provided by the system to evaluate that the feasible invention principle is “Extraction” and don’t want to worsen the parameter is “convenience of use.” Subsequently, it proposes to add a gap on the upper case of the vibration reduction device module of the hard disk drive, providing hand-holding area during assembly process that can solve the problem of difficulty of assembling the transmission cable.
Upon three-time improvement, the design target for improvement is acquired by the cluster's house of quality. It then uses “improved TRIZ diagnostic system" to acquire the innovation process of the parameters for improvement, invention principles and don’t want to worsen the parameter, which can reduce the direction error and reduce the time for innovation as compared with the traditional TRIZ.
Lastly, this paper searches and compares its content with the patent documents relating to the vibration reduction structure of the hard disk drive. It is found that the proposed project herein carries innovation in the vibration reduction structure of the hard disk drive, more stable transmission efficiency of the hard disk drive, improvement in easy to assemble and better usability in the industry.
