Bending Template with Concave Surface for Pipe Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing templates and jigs fail to accurately assist in creating complex bends in pipes, tubes, and bars, as they lack the capability to maintain planar orientation throughout multiple bends, leading to improper alignment and installation.
Innovation Solution
A template device with a body featuring parallel straight side edges and a concave surface, equipped with length and angle indicia, is used to mark an elongated element with start and finish lines and a guideline, ensuring that subsequent bends are made in the same plane or offset planes, facilitating precise complex bends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional templates are used for marking pipes, then cutting marks can be obtained, but the marks are poorly oriented for bending and cannot assist in creating complex bends with proper planar orientation
Solution Approach 1:
The template is divided into functional segments: a body portion for general positioning, straight edge portions for precise angle marking, and curved edge portions for complex bend patterns. Each segment can be used independently or in combination depending on the specific bending requirements.
Solution Approach 2:
The template serves multiple functions: it marks straight cuts, marks bending angles, guides complex multi-plane bends, and provides reference lines for maintaining planar orientation throughout sequential bending operations. The same template body accommodates both straight and curved edge portions for different applications.
2Adaptability or versatility
If multiple bends are created using a bending tool, then complex bend shapes can be achieved, but maintaining planar orientation becomes difficult and bends may rotate out of plane
Solution Approach 1:
The template pre-establishes all necessary reference lines, angle marks, and guideline indicators before the bending process begins. The user marks all bend locations and angles on the pipe using the template, creating a complete bending roadmap that ensures planar orientation is maintained throughout subsequent bending operations.
Solution Approach 2:
The template provides continuous visual feedback through its markings: straight edges indicate when bends are at correct angles, guidelines show the intended bend path, and reference lines allow the user to verify that each bend maintains proper planar orientation relative to previous bends.
3Measurement precision
If a template is designed for cutting marks, then cutting precision is improved, but the template cannot assist with bending orientation and alignment
Solution Approach 1:
The template integrates both cutting and bending functions into a single tool. The straight edges provide accurate cutting marks while simultaneously serving as references for bending angles. The template body includes markings and features that convey both cutting depth/position information and bending orientation/alignment information.
Solution Approach 2:
The template combines previously separate functions (cutting guidance and bending guidance) into one unified device. The straight edge portions serve dual purposes: marking cut lines and establishing bend angle references. The curved edge portions provide both cut arcs and bend path guidance.

AI summary
A device and method of marking an elongated element for bending. A template is provided that has a body with a first end, an opposite second end, a first side edge, and a second side edge. The body also includes a concave surface that extends between the first end and the second end. Length indicia are disposed on the body adjacent the first straight side edge. Angle indicia are disposed on the body adjacent the first end. Utilizing a marker and the template, a start line and a finish line are marked onto the elongated element. Additionally, a guideline is marked on the elongated element that extends from the start line to the finish line. At least one bend is formed in the elongated element between the start line and the finish line. The bends progress along the marked guideline.
