Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If hydraulic power is used in 4-way indent tools, then crimping force is improved, but weight increases and ease of operation deteriorates
Solution Approach 1:
The patent replaces the hydraulic power system with a mechanical drive system consisting of a motor, drive screw, and cam mechanism. The motor rotates the drive screw which moves the cam arm, which in turn actuates the indenters through cam surfaces. This mechanical substitution eliminates heavy hydraulic components while maintaining sufficient crimping force through mechanical advantage in the cam mechanism.
2Ease of operation
If pneumatic power is used in 4-way indent tools, then ease of operation is improved, but adaptability deteriorates due to air hose connection requirement
Solution Approach 1:
The patent replaces the pneumatic system with an electric motor-driven mechanical system. The motor can be battery-operated or cordless, eliminating the need for air hose connections. This provides the same ease of operation as pneumatic tools while significantly improving adaptability and flexibility for use in various locations without infrastructure requirements.
3Adaptability or versatility
If hand-powered operation is used, then adaptability is improved, but manufacturing precision deteriorates due to inconsistent crimps
Solution Approach 1:
The patent replaces manual hand operation with an automated motor-driven mechanical system. The motor provides consistent rotational speed and torque, the drive screw ensures precise linear movement of the cam arm, and the cam mechanism delivers repeatable indenter actuation forces. This automation eliminates operator variability while maintaining the adaptability of a portable tool design.
Solution Approach 2:
The patent incorporates a crimp height adjustment mechanism that allows modification of the cam profile or drive screw positioning to control the depth and force of crimping. This parameter adjustment capability ensures consistent, repeatable crimps across different operations while maintaining portability and adaptability.
4Manufacturing precision
If motor-driven mechanical system is used, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the drive system into distinct functional modules: a motor module, a drive screw module, a cam arm module, and an indenter module. Each module performs a specific function and can be independently adjusted or maintained. The crimp height adjustment mechanism is separated as an independent adjustment system, allowing precise control without complicating the overall drive mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool achieves repeatable and reliable crimping operations with adjustable crimp height and reduced operator fatigue, enhancing flexibility and usability.
Implementation Method 1
a drive screw operably coupled to the motor and being rotated by the motor when the motor is operated... The drive nut is moved linearly on the drive screw between an unactuated position and an actuated position
Implementation Method 2
The indenter actuator cam arm has cam surfaces engaging the corresponding indenters to actuate the indenters. The indenter actuator cam arm is coupled to the drive nut and moves with the drive nut between the unactuated position and the actuated position to actuate the indenters
