Speaker Mounting Device Anti-Theft Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker mounting devices can be easily dismounted from high positions using a bar or similar tool, increasing the risk of mischief or theft, and while securing the speaker with a disengagement prevention tool makes it difficult to mount or dismount, it becomes burdensome.
Innovation Solution
A speaker mounting device configuration where the speaker component is slid backward and downward for mounting and forward and upward for dismounting, incorporating a movement prevention member and shaft member with a rotational axis, requiring a tool to rotate the movement prevention member to lock or unlock the speaker to the wall, preventing unauthorized dismounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the speaker is mounted using a conventional lock mechanism with a fastener member and fastening hole, then the speaker can be easily mounted and dismounted, but the speaker can be easily dismounted using a bar or tool, increasing the risk of mischief or theft
Solution Approach 1:
The patent inverts the conventional dismounting logic by requiring a specific rotational action on the shaft member to move the movement prevention member. Instead of simply pulling or sliding the speaker component off, the user must rotate the shaft member in a specific direction to retract the movement prevention member from the inserted section, thereby preventing unauthorized dismounting while maintaining controlled accessibility for authorized users with the proper tool
Solution Approach 2:
The movement prevention member acts as an intermediary element between the speaker component and wall component. This intermediate component physically blocks the inserted section when engaged, creating an additional layer of security. The shaft member then controls the movement prevention member's position, mediating between the user's action and the locking/unlocking state
2Object-affected harmful factors
If a disengagement prevention tool is used to firmly mount the speaker to the wall, then the speaker is secured against unauthorized dismounting, but the mounting work and dismounting work become considerably burdensome
Solution Approach 1:
The patent introduces dynamic elements through the rotatable shaft member and the movable movement prevention member. Instead of a static, permanently fixed mounting system, the design allows the movement prevention member to be dynamically repositioned between engaged and retracted states through rotation of the shaft member. This dynamic mechanism enables easy transition between locked and unlocked states, reducing the burden of mounting and dismounting while maintaining security when engaged
Solution Approach 2:
The movement prevention member is preliminarily positioned to engage with the inserted section during the mounting process. By pre-configuring this blocking element to automatically engage when the speaker component is installed, the system provides immediate security without requiring additional separate securing steps, thereby reducing overall mounting burden while preventing unauthorized dismounting
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 device securely mounts the speaker to the wall, preventing unauthorized dismounting without a tool while allowing easy dismounting with a tool, enhancing security and simplifying the mounting and dismounting process.
Implementation Method 1
the shaft member is rotatable to cause the movement prevention member to rotate around the shaft member which has a rotational axis
Implementation Method 2
the shaft member has an outer end of a screw head shape or a bolt head shape; and the movement prevention member, in a state in which the speaker component is mounted to the wall component, is configured to be positioned in the backward and downward direction relative to the wall component by rotation of the shaft member

AI summary
An object of the present invention is to provide a speaker mounting device which does not permit a dismounting work without using a tool but enables an easy dismounting work using the tool. A speaker mounting device 1 of the present invention comprises a speaker component 2 provided at a speaker, and a wall component 3 to be provided at a wall. The speaker component 2 is configured to be slid in a first direction with respect to the wall component to be mounted to the wall component 3. The speaker component 2 is configured to be slid in a second direction with respect to the wall component 3 to be dismounted from the wall component 3. The speaker component 1 includes a movement prevention member 5 and a shaft member 6 coupled to the movement prevention member 5. The shaft member 6 is rotated to cause the movement prevention member 5 to rotate around the shaft member 6 which is a rotational axis. The shaft member 6 has an outer end of a screw head shape or a bolt head shape. The wall component 3 is positioned in the second direction relative to a rotational trajectory of the movement prevention member 5 in a state where the speaker component 2 is mounted to the wall component 3.
