Terminal-Bracket Locking Assembly for Tool-Free Anti-Tamper Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminals with fingerprint recognition devices are vulnerable to unauthorized disassembly, leading to data tampering, and their installation is inconvenient due to the need for tools and time-consuming screw fastening.
Innovation Solution
A terminal apparatus assembly with a locking unit that includes movable inner lockers, allowing secure fastening and separation from a bracket using a tool-free mechanism, featuring a first inner locker and a second inner locker that engage and disengage with a restoring force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw fastening method is used to fix the terminal to the bracket, then the terminal can be securely fixed, but additional tools are required and installation time increases
Solution Approach 1:
The locking unit enables self-service installation by incorporating a restoring force mechanism that automatically returns the inner locking part to its initial position after compression. This eliminates the need for external tools like screwdrivers, allowing users to simply press the inner locking part to secure the terminal to the bracket without requiring additional installation tools or complex procedures.

3Ease of operation
If the terminal is freely disassembled by unauthorized outsiders, then easy access is achieved, but information and data can be tampered with
Solution Approach 1:
The locking unit employs a dynamic locking mechanism where the inner locking part can be compressed to change its position. When compressed, the inner locking part moves to a locked position that secures the terminal to the bracket. When released, the restoring force returns the inner locking part to its initial position, enabling controlled access while preventing unauthorized disassembly and data tampering.
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 solution provides convenient and secure fixation of terminals to brackets, preventing unauthorized disassembly and enhancing installation efficiency while protecting against tampering.
Implementation Method 1
the second inner locker being movable toward the bracket when the lower portion is pressed by either the external force or the first inner locker and being movable in a direction away from the bracket when pressing by the external force is released
Implementation Method 2
the inner locking part is configured to move in one direction toward the bracket or the terminal when at least a portion is pressed by an external force and to move in a direction opposite to the one direction by a restoring force when the pressing is released

AI summary
A terminal apparatus assembly includes: a terminal configured to be selectively fastened to a bracket; and a locking unit including an inner locking part configured to be movable with respect to the bracket such that the terminal and the bracket are fastened to or separated from each other. The inner locking part is configured to move in one direction toward the bracket or the terminal when at least a portion is pressed by an external force and to move in a direction opposite to the one direction by a restoring force when the pressing is released.
