Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing blind fastener setting tools are used, then the fastening function is achieved, but the device is cumbersome and requires multiple steps making it time-consuming
Solution Approach 1:
The patent combines multiple functions (delivery, clamping, setting, and drilling operations) into a single integrated tool head assembly. The tool shaft integrates the setting device with the drill bit, eliminating the need for separate delivery mechanisms and multiple操作步骤, thus improving productivity while maintaining manageable complexity
Solution Approach 2:
The tool shaft serves multiple functions: it delivers the blind fastener, clamps it in position, performs the setting operation by rotating the fastener, and then drills the hole. This multi-functional design eliminates the need for separate tools for each operation, significantly improving setting speed and productivity
2Loss of time
If existing setting devices are used, then the fastening operation is completed, but multiple steps are required making the process time-consuming
Solution Approach 1:
The patent enables continuous operation where the tool shaft performs delivery, clamping, setting, and drilling in an uninterrupted sequence. The automatic indexing mechanism ensures smooth transitions between operations without manual intervention, reducing production time while maintaining operational simplicity through automation
Solution Approach 2:
The blind fastener is pre-loaded into the tool shaft's delivery mechanism before the setting operation begins. The tool shaft is pre-positioned and the clamping mechanism is ready to engage, allowing the setting operation to start immediately without preparation time, thus reducing overall production time
3Extent of automation
If automated setting is implemented, then efficiency is improved, but precise control of position and load is needed increasing device complexity
Solution Approach 1:
The patent incorporates sensors that detect the position of the tool shaft and the load applied during the setting operation. This feedback is used by the control system to automatically adjust parameters and ensure precise control, enabling high-level automation while managing complexity through intelligent control algorithms
Solution Approach 2:
The patent replaces manual mechanical control with an automated control system that uses electrical signals and sensors to control the tool shaft's movements and apply precise loads. This substitution enables automated setting with precise control while reducing the complexity of manual mechanical linkages

AI summary
Setting tool (10) for blind fasteners comprising a first electric motor (36) with a first drive shaft, which is arranged in a first housing portion (28) and is connected to a tool housing portion (26) via a first transmission device; a tool shaft (32) arranged in the tool housing portion (26), with which a screw tool (34) is connected, wherein the screw tool (34) is rotationally and translationally movable along and around a longitudinal axis (X) between a retracted position and an extended position; a feeder (18) with a fastener delivery tube (66) and a blind fastener supply, the delivery tube (66) being connected at a first end to the blind fastener supply and at a second end to the tool housing portion (26) for delivering the blind fastener in the tool housing portion (26) in front of the screw tool (34) when the screw tool is in the retracted position. The setting tool for blind fasteners further comprises a second electric motor (38) with a second drive shaft, which is arranged in a second housing portion (30) and is connected to the tool housing portion (26) via a second transmission device. The delivery tube (66) merges with the tool housing portion through a receiver assembly (68), the receiver assembly comprising an interface channel (70) connecting directly the delivery tube with the tool housing portion, such that the screw tool (34) can engage with a blind fastener within the tool housing portion.
