Pre-positioning Device for Drywall Electrical Box Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current method of assembling drywall or false ceilings is inefficient due to the need for electricians to intervene multiple times, leading to difficulties in pre-wiring and testing electrical installations, with risks of cable loss and connection faults, especially due to the 67mm hole size making manual retrieval challenging and prone to errors.
Innovation Solution
A pre-positioning device comprising a strip with marks for fixing templates, a holding member for profiled uprights, and a template with a slot for flush-mounting boxes, allowing precise placement and attachment of cables and sheaths before plasterboard closure, enabling early wiring and functionality testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conduits and cables are pre-positioned using adhesive tape and makeshift methods, then electrical wiring can be prepared in advance, but the conduits and cables are easily displaced or lost due to dust and improper fixation
Solution Approach 1:
The patent applies preliminary action by providing templates with pre-marked positions for conduits and cables before the partition assembly begins. These templates are fixed to the profiled studs in advance, establishing precise locations for electrical components before plasterboard installation, thereby preventing displacement and loss issues that occur with makeshift methods.
Solution Approach 2:
The patent introduces templates as an intermediary device between the profiled studs and the conduits/cables. These templates serve as a stable intermediary structure that maintains precise positioning of electrical components throughout the assembly process, eliminating the need for unreliable adhesive tape fixation.
2Ease of operation
If a 67mm diameter hole is drilled in the plasterboard to access conduits and cables, then electrical fittings can be installed, but the hole size is too large to allow manual retrieval of conduits and cables
Solution Approach 1:
The patent applies preliminary action by pre-positioning conduits and cables within template-guided locations before plasterboard installation. This ensures that when the 67mm hole is drilled, the conduits and cables remain in their designated positions and can be easily accessed without requiring manual retrieval through the large hole.
3Reliability
If electricians intervene multiple times during partition assembly, then electrical wiring can be prepared and finalized, but the process becomes complex and time-consuming with repeated access required
Solution Approach 1:
The patent applies preliminary action by enabling electricians to complete conduit and cable positioning during the initial partition assembly phase using templates. This preliminary electrical work eliminates the need for multiple subsequent interventions, as all wiring准备工作 is completed before the partition is closed, thereby reducing process complexity while maintaining installation completeness.
4Reliability
If electrical functionality testing is performed at the very end of installation, then connection faults can be detected, but the complexity of troubleshooting increases and additional work may be required to access components
Solution Approach 1:
The patent applies preliminary action by enabling electrical functionality testing to be performed during the initial assembly phase when templates and conduits are pre-positioned. This early testing allows connection faults to be detected and corrected before the partition is closed, significantly reducing troubleshooting complexity and time compared to end-of-installation testing.
