Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual bending is used to bend conductive terminals, then each terminal can be bent individually, but bending efficiency is limited and time consumption increases
Solution Approach 1:
The patent combines multiple bending operations into a single tool structure. The plate contains multiple receiving grooves that can simultaneously hold multiple conductive terminals, and multiple rollers can simultaneously bend multiple terminals in one operation, transforming individual sequential bending into parallel simultaneous bending.
Solution Approach 2:
The plate is segmented into multiple receiving grooves, each capable of independently positioning and bending a conductive terminal. This segmentation allows the tool to process multiple terminals simultaneously while maintaining individual control over each bending operation.
2Ease of operation
If manual bending is used to bend conductive terminals, then flexibility in operation is maintained, but bending accuracy deteriorates and position errors increase
Solution Approach 1:
The receiving grooves are pre-configured with specific geometries and positions to guide the conductive terminals into correct orientations before bending. The rollers are pre-positioned at precise locations to apply bending force at the exact required positions, ensuring consistent bending accuracy without requiring manual positioning adjustments.
3Ease of manufacture
If manual bending with clamping tools is used, then bending operation can be performed, but surface scratches occur and terminal quality deteriorates
Solution Approach 1:
The patent replaces the traditional clamping and gripping mechanical action with a rolling contact mechanism. Instead of clamping the terminal with pliers that create localized high-stress contact points and scratches, the rollers provide distributed rolling contact that bends the terminal smoothly without surface damage.

AI summary
A terminal bending tool comprises a plate, a plurality of receiving grooves, and a plurality of rollers. The plate extends in a first horizontal direction. The receiving grooves are disposed in the plate in a row along the first horizontal direction. The rollers are pivotally mounted in the receiving grooves. A terminal is received and positioned in a first receiving groove and is in contact with an outer circumferential surface of a first roller. When the terminal bending tool is moved in a vertical direction perpendicular to the first horizontal direction, the first roller rotates and moves along a surface of the terminal while pressing and bending the terminal.
