Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal apparatuses with screw connections for fingerprint recognition devices are time-consuming to install and inconvenient, and they are vulnerable to unauthorized disassembly, which can lead to data tampering.
Innovation Solution
A terminal apparatus with a hook connection method to the bracket, featuring a locker unit with movable lockers and elastic members for secure engagement and easy installation, along with a detection switch and tamper unit for security, preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw connection method is used to fix the terminal apparatus to the bracket, then the connection is secure and reliable, but the installation time increases and convenience is reduced
Solution Approach 1:
The patent replaces the traditional screw connection mechanical system with a hook connection system. The case hook engages with the bracket through a simple hooking motion, eliminating the need for screws, drill holes, and complex fastening operations. This substitution maintains connection reliability while dramatically reducing installation time and improving convenience.
2Ease of operation
If the terminal apparatus is easily disassembled for convenience, then installation and maintenance become simpler, but security against unauthorized access is reduced
Solution Approach 1:
The patent implements a dynamic locking system where the locker unit can move between locked and unlocked positions. When locked, the locker prevents the case from being removed from the bracket. When unlocked, the case can be easily detached. This dynamic mechanism provides both security during normal operation and convenience during authorized maintenance or installation.
Solution Approach 2:
The locker unit acts as an intermediary between the case and the bracket. It controls the engagement and disengagement of the case hook with the bracket, providing security when locked and enabling easy removal when unlocked. This intermediary mechanism resolves the contradiction between security and ease of operation.
3Device complexity
If a simple connection method is used to reduce installation complexity, then installation time is reduced, but the prevention of unauthorized disassembly is weakened
Solution Approach 1:
The patent segments the connection system into distinct functional components: the case hook for engagement, the locker unit for security control, and the bracket for mounting. This segmentation allows the system to achieve simple installation through the hook mechanism while incorporating security features through the locker unit, thereby reducing overall complexity while preventing unauthorized disassembly.
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
The hook connection method significantly reduces installation time and enhances security by preventing unauthorized disassembly and data tampering, ensuring secure and efficient mounting of the terminal apparatus.
Implementation Method 1
an elastic portion disposed adjacent to the locker unit... a main elastic member applying a restoring force to the second locker to allow the second locker to move toward the bracket

AI summary
A terminal apparatus includes: a case configured to be selectively engaged with a bracket installed on a wall; and a locker unit configured to move with respect to the bracket to prevent the case from coming out of the engagement or to allow the case to come out of the engagement. The locker unit includes a first locker configured to move in a first direction by an external force applied by a user, and a second locker configured to move in a second direction different from the first direction by the movement of the first locker.
