Folding Tilting Circular Saw Frame for Compact Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tilting circular saws are not optimized for a broad range of applications and user groups, with limitations in mobility, storage, and safety features.
Innovation Solution
A tilting circular saw with a frame designed as Nuremberg scissors, featuring a releasable locking device for folding into a compact transport position, a pivoting cuttings receiving channel, and safety features like a damper to prevent kickback, along with a robust yet lightweight construction using double scissors and a saw blade cover for reduced injury risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the frame is designed as a fixed structure to ensure stability during operation, then operational stability is improved, but mobility and storage efficiency deteriorate
Solution Approach 1:
The frame is designed with dynamic characteristics, allowing it to transition between an extended operational position providing stability during sawing and a folded transport position reducing storage volume. The scissor-like mechanism enables the frame to adapt its configuration based on operational requirements.
2Reliability
If the frame is made robust to ensure operational reliability, then reliability is improved, but weight increases
Solution Approach 1:
The frame utilizes a composite structure combining rigid elements for stability with lighter materials where possible. The scissor-like mechanism employs a clever arrangement of connected elements that provide structural strength through geometric configuration rather than simply increasing material mass, achieving reliability while controlling weight.
3Productivity
If the saw blade is positioned to provide optimal cutting performance, then cutting performance is improved, but accessibility for operators deteriorates
Solution Approach 1:
The saw blade is positioned in a vertically oriented plane rather than a horizontal position, creating additional spatial dimension for operator access. This vertical arrangement allows operators to approach and operate the saw from multiple sides while maintaining optimal cutting geometry, solving the accessibility issue without compromising cutting performance.

AI summary
The invention relates to a tilting circular saw with a frame (1) on which a saw blade (2) is mounted stationary and rotatably about a preferably horizontal axis of rotation, and on which a rotary drive (3) for the saw blade (2) is attached, and with a rocker (4) which includes a material receiving channel (6) mounted on the upper side of an arm (5). A bearing arrangement (16, 17, 18) is provided on which the arm (5) is pivotably mounted on the underside of the frame (1) about an axis parallel to the axis of rotation, so that the material receiving channel (6) can be pivoted between a sawing position and a material loading position, towards and away from the saw blade (2).The invention is characterized in that the frame (1) is designed as a Nuremberg scissor with pivot axes (19) running parallel to the axis of rotation and has a releasable locking device (10, 19, 20, 21) to lock the frame (1) in an upright working position or to lower it into a folded transport position, and the bearing arrangement (16, 17, 18) is releasable in order to place the rocker (4), which in the working position is articulated to the frame (1) with its arm (5), onto the frame (1) folded into the transport position when the bearing arrangement (16, 17, 18) is released, so that a cuboid packing volume enclosing the rocker circular saw in the transport position is smaller than a cuboid packing volume enclosing the rocker circular saw in the working position would be.
