Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual bending is used for guide wires, then the operation is simple and quick, but the bending angle precision deteriorates
Solution Approach 1:
The guide wire itself serves as the measuring tool by utilizing its own diameter as the radius for bending. The wire is wrapped around itself to form a loop, where the bend radius automatically equals the wire diameter, ensuring consistent and accurate bending angles without requiring external measuring instruments or complex positioning mechanisms.
Solution Approach 2:
The bending process is divided into distinct functional zones: a fixed support section that anchors the wire, a bending section where the wire is wrapped around itself, and a free end section. This segmentation allows each zone to perform its specific function optimally - the fixed section provides stability, the bending section creates the precise angle, and the free section maintains flexibility.
2Strength
If traditional angle bending tools are used, then they work for thicker metal materials, but they are not suitable for thin guide wires with diameter less than 1 mm
Solution Approach 1:
The invention changes the fundamental parameter of bending radius from being externally imposed (by tool geometry) to being inherently determined by the wire's own diameter. This parameter change makes the method universally applicable across different wire thicknesses, as each wire automatically adapts to its appropriate bend radius based on its own dimensions, eliminating the need for tool adjustments.
Solution Approach 2:
The self-wrapping bending method is universally applicable to guide wires of various diameters and materials. The same basic technique works for thin wires (less than 1 mm) and can be adapted for thicker materials, making it a versatile solution that replaces multiple specialized tools with a single universal method.
3Device complexity
If visual inspection and experience-based manual bending is used, then no special equipment is needed, but the bending accuracy deteriorates leading to surgical failures
Solution Approach 1:
The guide wire serves its own measurement function by using its diameter as the bending radius. This eliminates the need for external measuring tools, positioning devices, or complex equipment while ensuring consistent and reliable bending accuracy. The method transforms the wire from being merely the object to be bent into both the object and the measuring standard.
Solution Approach 2:
The wire's own diameter acts as an intermediary standard that mediates between the bending force and the final bend angle. Instead of relying on the operator's subjective judgment or experience, the physical dimension of the wire itself becomes the objective reference that ensures accurate and repeatable bending results.

AI summary
A device for shaping an angle of a guide wire includes a support platform configured to provide a support surface for placing the guide wire, and an angled cutter head configured to press and bend the guide wire at an accurate angle. A method for shaping with a device for shaping an angle of a guide wire includes the following steps: placing a guide wire on a support platform, extending out the guide wire by a certain bending length, pressing down on the guide wire with an angled cutter head of which the bottom surface is provided with a certain angle, and preparing the guide wire of which one end has an angle of required accuracy.
