Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet metal folding tools are unwieldy and heavy, making them unsuitable for simple bending or folding of metal sheets on facades.
Innovation Solution
A compact and lightweight folding pliers design with rotatably connected clamping surfaces and pivotally connected handles, allowing for easy clamping and bending of sheet metal, featuring a first axis of rotation and a second axis of rotation approximately parallel, with a distance between them less than 20 cm, and utilizing a hinge connection and spring-loaded joints for efficient force transmission and smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional folding pliers design is used, then bending function is achieved, but weight and size increase making tool cumbersome and heavy
Solution Approach 1:
The folding pliers is divided into separate functional components: a first clamping surface assembly with first handle connected by first rotation axis, and a second clamping surface assembly with second handle connected by second rotation axis. This segmentation allows each component to be optimized independently for weight and function, reducing overall tool weight while maintaining operational effectiveness for facade sheet metal bending.
2Manufacturing precision
If clamping surfaces extend across entire sheet width, then continuous clamping is achieved, but device complexity and size increase
Solution Approach 1:
The invention extracts and separates the clamping function from the bending function into distinct assemblies. The first clamping surface and second clamping surface are positioned to clamp the sheet at specific locations rather than extending continuously across the entire sheet width. This extraction achieves clean bending edges through concentrated clamping force while reducing the overall size and complexity of the clamping surface arrangement.
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 tool is lightweight, easy to handle, and suitable for mobile use, ensuring clean edges and robust performance, enabling efficient bending of sheet metal on facades with minimal space requirements and easy transport.
Implementation Method 1
a rotatable connection between the clamping surfaces and/or between the second clamping surface and the second handle is formed by a hinge, particularly a rod hinge
Implementation Method 2
at least one spring is provided on a joint which forms the second rotary axis, in particular a rod hinge forming the second rotary axis, with which spring a frictional force acting between parts of the joint which are movable relative to one another can be introduced into the joint
Implementation Method 3
with which spring a frictional force acting between parts of the joint which are movable relative to one another can be introduced into the joint
Implementation Method 4
a sheet can be completely clamped, preferably in a region between the first rotation axis and the second rotation axis, in order to apply even load to the sheet

AI summary
The invention relates to folding pliers (1) for bending sheet metal (8), having a first clamping area (2) and a second clamping area (3), wherein the clamping areas (2, 3) are connected rotatably about a first rotation axis (4), and also a first grip piece (6) and a second grip piece (7) pivotably connected to the first grip piece (6), wherein the first grip piece (6) is connected to the first clamping area (2). In order to achieve a tool that is robust and at the same time easy to handle, it is provided according to the invention that the second grip piece (7) is connected to the second clamping area (3) rotatably about a second rotation axis (5), so that, when the first grip piece (6) is pivoted in relation to the second grip piece (7) out of a transporting position, the first clamping area (2) is moved in relation to the second clamping area (3) in such a way that a sheet (8) arranged between the clamping areas (2, 3) can be clamped by the clamping areas (2, 3), after which a further pivoting movement of the first grip piece (6) in relation to the second grip piece (7) brings about a rotating movement of the first clamping area (2) together with the second clamping area (3) in relation to the second grip piece (7) about the second rotation axis (5) in order to bend the clamped sheet (8).
