| Summary: | Mortise locks are generally used for exterior doors due to its high durability in sustaining the security level of house access systems. This type of door lock systems have been implemented on all kinds of houses for more than 70 years. However, the mechanical principle of present mortise locks have remained the same, even though they differ slightly in terms of their exterior that caters to the design of security doors. The mortise principle of this type of lock requires a definite key to lock and unlock the security door. One main drawback of the existing security door lock is that, it is almost impossible to instantly lock the door by inserting the key exactly into the hole of the lock especially during times of emergency. This is the reason why recent burglary reports claim that there is no evidence of breaking-in but the house owner is robbed. Burglary is a crime where unlawful enter a resistanceless house or building through several entrances such as door or window. Burglary may not always happened through the door, yet the percentage of forced entry through housing doors is very high. In addition, this will not only lead to the threat for valuable items, but also to human life. The weak security protection of conventional mortise locks literally renders the premise defenceless against burglaries. The call to enhance functionality of security door locks is imminent. Thus, this present study is undertaken to overcome the drawback stated above by devising and developing an innovative idea of security door locking system. The features of security door locking system included does not require a key or electricity to lock the door, cannot unlock the door without the key and can lock the door instantly. Analytic Hierarchy Process (AHP) decision making tool as well as multi-aspect Quality Function Development (QFD) method are utilised during the stages of design and operational screening. Moreover, sensitivity analysis also had implemented in this study and justified that Concept 1 is the most appropriate design concept of security door locking system compared with another two concepts. The fabricated prototype had go through the simulation and analysis process for performance evaluation and validation. Consequently, the Auto Security Door Locking Syatem (ASD-Lock) will be proposed to attract manufacturers as this solution has high potentials in overcoming the drawbacks of the current mortise locks. |
