Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional cutting tools (saw, disc, or shear) are used to cut open profiles, then the cutting operation can be performed, but the profile deforms due to low material stiffness and complex shape
Solution Approach 1:
The cutting action is segmented into two separate parallel cutting edges that simultaneously cut through the profile. This segmentation allows each cutting edge to work independently on opposite sides of the profile, distributing the cutting force and preventing deformation that would occur with a single cutting tool.
Solution Approach 2:
The invention transitions from single-plane cutting to dual-plane cutting by introducing two parallel cutting edges separated by a specific distance. This dimensional change allows the tool to cut through the profile from multiple planes simultaneously, maintaining structural integrity during the cutting process.
2Productivity
If traditional cutting tools are used on open profiles, then cutting can be achieved, but long dangerous chips are produced
Solution Approach 1:
The chip formation process is segmented by the two parallel cutting edges that create multiple smaller chip segments rather than one long continuous chip. This segmentation of the chip structure eliminates the safety hazard of long chips while maintaining cutting effectiveness.
3Device complexity
If a single cutting plane is used, then the tool structure is simple, but it cannot effectively cut profiles without deformation
Solution Approach 1:
Two cutting planes are merged into a single integrated blade structure with two parallel cutting edges. This merging maintains relative structural simplicity while achieving the precision and quality of dual-plane cutting, as both cutting edges are mounted on the same movable blade assembly.

AI summary
The invention relates to a cutting tool for severing profiles having an open cross section, the tool comprising a base (1) and a blade (2) having two opposite ends, said blade being moveably mounted on a support (3) which is attached to the base (1) and which enables the blade (2) to be moved in a cutting plane between an open position for accommodating, between the support (3) and the blade (2), a profile which is to be severed, and a closed position at the end of a cutting operation. The support (3) comprises a die (7) which is intended to be covered by the profile to be severed and which is provided with a slot intended to receive the blade (2) during a cutting operation, and the blade (2) comprises a punch situated between the two opposite ends, and two flat cutting edges extending from the punch towards one or other of the two ends, respectively.
