Wall-Mounted Electrical Device Levelling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical devices for wall mounting face difficulties in levelling due to the need for manual adjustment with one hand while holding the mounting frame or a spirit level, often risking damage during the process.
Innovation Solution
An electrical device with a mounting frame featuring a moveable fixation and levelling device, including a slidable fixation element and an adjustment element, which allows for easy levelling and alignment with a horizontal plane using a screwdriver, and a visible spirit level for accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment is performed with one hand while holding the mounting frame or spirit level, then levelling can be achieved, but the operation becomes difficult and risks damaging the mounting frame
Solution Approach 1:
The fixation element is designed to be self-adjusting through its interaction with the elongated orifice. When the fixation screw is inserted, the fixation element automatically slides along the elongated orifice to achieve proper alignment and levelling without requiring manual manipulation of the mounting frame or spirit level by the installer.
Solution Approach 2:
The fixation element acts as an intermediary between the fixation screw and the mounting frame. It translates the linear motion of the fixation screw into positional adjustment of the entire mounting frame, enabling precise levelling control without direct manual handling of the frame itself.
2Measurement precision
If the mounting frame is forced into horizontal position with fixation screw partially screwed on, then levelling can be achieved, but the mounting frame risks damage
Solution Approach 1:
The fixation element is designed with dynamic capability to slide along the elongated orifices during the fixation process. This dynamic adjustment allows the mounting frame to be gradually guided into horizontal position as the fixation screw is progressively tightened, rather than being forcibly positioned, thereby preventing damage to the mounting frame.
3Adaptability or versatility
If elongated fixation holes are used for adjustment and levelling, then positioning flexibility is provided, but the levelling process becomes uneasy and complex
Solution Approach 1:
The fixation element serves multiple functions simultaneously: it acts as a positioning guide within the elongated orifices, a levelling mechanism through its sliding motion, and a fixation component that secures the mounting frame to the wall. This multi-functionality simplifies the overall levelling process while maintaining positioning flexibility.
