Ceiling Hanger Wire Bending Head for Ground-Level Precise Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current method for bending suspended ceiling support rods/hanger wires is inefficient and labor-intensive, requiring frequent climbing and use of multiple tools, as installers must manually position a scaffold or ladder to accurately bend wires for a horizontal ceiling installation.
Innovation Solution
A long pole-based bending device with a rotatable handgrip, a head module featuring a channel for the hanger wire, and a motor-driven push member, which allows for precise bending without the need for scaffolding, using a laser light reflecting plate for accurate positioning and a magnet to hold the wire in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual bending with pliers and measuring tape is used, then bending precision can be achieved, but installation time and labor intensity increase significantly
Solution Approach 1:
The patent combines multiple functions (measuring, marking, bending) into a single integrated tool. The L-shaped tool merges the measuring tape and bending tool into one device, allowing the installer to complete all operations without switching tools or equipment, thereby improving both precision and efficiency.
Solution Approach 2:
The L-shaped tool serves multiple purposes: the vertical portion acts as a measuring tape for determining bend location, while the horizontal portion serves as a bending lever. This multi-functional design eliminates the need for separate measuring tapes and pliers, reducing tool handling time and improving installation productivity.
2Measurement precision
If scaffolding or stepladder is used for positioning, then accurate bend location can be achieved, but setup time and installer fatigue increase
Solution Approach 1:
The patent extracts the positioning function from the scaffold/stepladder system and integrates it directly into the bending tool itself. The vertical portion of the L-shaped tool provides built-in positioning and measurement capabilities, eliminating the need for separate scaffolding equipment and reducing setup time.
Solution Approach 2:
The tool is designed to be self-positioning and self-measuring. The installer simply holds the tool against the wire, and the vertical portion automatically provides the measurement reference for the correct bend location, eliminating the need for external positioning aids like scaffolding.
3Manufacturing precision
If multiple separate tools are used for measuring and bending, then functional precision is maintained, but device complexity and操作流程 difficulty increase
Solution Approach 1:
The patent merges the measuring tape and bending tool into a single L-shaped integrated tool. This consolidation maintains measurement accuracy through the vertical portion while providing bending capability through the horizontal portion, all within one simple device rather than multiple separate tools.

AI summary
A wire bending device is adapted for bending hanger wires hanging from a ceiling in preparation of the installation of rails of a suspended ceiling. The bending device comprises a pole having a top extremity, a head module mounted to the pole, and a pair of handles distant from the head module for holding and activating the head module. The head module comprises a casing, a motor enclosed in the casing, a channel housed by the casing for receiving the hanger wire; and a push member driven by the motor travelling between an hanger wire insert position and a wire bend position, wherein the push member is adapted to push against the hanger wire and bend the hanger wire during its travel. Thereby, one may operate the bending device from the ground and bend hanger wires for installation of suspended ceiling rails.
