Lock Shell Assembly with Elastic Joint for Separable Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lock shells are not separably designed, making it costly and time-consuming to change the latch bolt shell when updating a lock, as they are firmly attached and difficult to dismantle.
Innovation Solution
A shell assembly with elastic joint components on one shell and corresponding cavities and protrusions on another, allowing for resilient connection and easy removal and replacement, featuring a first shell with a cavity and protruding components and a second shell with concavities and apertures for secure, separable engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shell is firmly attached to the latch bolt or door with irremovable configuration, then the shell is securely fixed and stable, but it is hard to dismantle and replace the shell
Solution Approach 1:
The shell assembly is divided into two separable parts: a first shell that is firmly attached to the latch bolt mechanism, and a second shell that can be easily removed and replaced. The joint component connects these two shells, allowing the second shell to be detached without affecting the secure attachment of the first shell to the mechanism.
Solution Approach 2:
The joint component incorporates elastic elements that provide dynamic connection between the first and second shells. This elastic connection allows the shells to be securely held together during normal use, while enabling easy separation when needed for replacement or maintenance.
2Reliability
If the shell is firmly attached to the latch bolt mechanism, then the shell is stable and secure, but it takes a lot of cost and time to change the shell
Solution Approach 1:
The shell is segmented into a replaceable second shell and a permanent first shell. This allows only the decorative outer shell to be replaced rather than the entire lock assembly, significantly reducing the time and cost of shell changes while maintaining secure attachment of the mechanism.
Solution Approach 2:
The second shell is extracted as a separate, independently replaceable component from the overall lock assembly. This extraction allows the shell to be changed without disturbing the latch bolt mechanism or requiring complex disassembly procedures.
3Adaptability or versatility
If the entire lock mechanism is changed to update the lock appearance, then the appearance is updated, but it is costly and time-consuming
Solution Approach 1:
The lock system is segmented into a permanent mechanism part and a replaceable appearance shell. This allows the appearance to be updated by replacing only the second shell rather than the entire lock mechanism, reducing costs and enabling easier customization.
Solution Approach 2:
The first shell serves multiple functions: it provides structural support, secures the latch bolt mechanism, and serves as a mounting base for different decorative second shells. This multi-functionality allows various appearances to be achieved while maintaining a single, permanent functional core.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and cost-effective interchangeability of lock shell appearances without damaging the lock mechanism, facilitating decorative changes and reducing the time and expense associated with replacing lock shells.
Implementation Method 1
a first shell having an elastic joint component securely formed on a side face of the first shell... such that the first shell and the second shell are separably connected together due to resilience provided by the joint component
Data Source
AI summary
A shell assembly includes a first shell having an elastic joint component securely formed on a side face of the first shell, a second shell received in the first shell having a concavity to correspondingly partially receive therein the joint component, such that the first shell and the second shell are separably connected together for a replacement application.
