Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct magnetic field acceleration is used to accelerate the striking element, then control over striking behavior is improved, but striking force is insufficient
Solution Approach 1:
The patent introduces a spring element that dynamically changes the mass characteristics of the striking element during acceleration. The spring is compressed during the acceleration phase and then releases stored energy during the striking phase, creating a dynamic system that adapts its effective mass based on the operational phase, thereby achieving both control and high striking force
Solution Approach 2:
The patent changes the physical state and parameters of the spring element throughout the operational cycle. The spring transitions from an uncompressed state during acceleration to a compressed state during impact, effectively changing the mass parameter of the striking element from m to (m+Ms) at the moment of impact, thereby increasing striking force while maintaining control during the acceleration phase
2Ease of operation
If magnetic field acceleration is used, then striking mechanism control is improved, but energy utilization efficiency is insufficient
Solution Approach 1:
The spring element performs preliminary action by being compressed during the acceleration phase, storing energy that will be released later. This preliminary compression of the spring allows the system to accumulate energy during the controlled acceleration phase and then release it during the striking phase, improving overall energy utilization efficiency
Solution Approach 2:
The spring element ensures continuity of useful action by continuously storing energy during the acceleration phase and then continuously releasing it during the striking phase. This continuous energy transfer from the spring to the striking element maintains efficient energy utilization throughout the entire operational cycle, rather than having energy losses between discrete phases
3Force
If the striking element mass is increased to improve striking force, then striking force is improved, but acceleration by magnetic field becomes less efficient
Solution Approach 1:
The system dynamically adjusts the effective mass of the striking element during the operational cycle. During the acceleration phase, only the base mass m is accelerated by the magnetic field, maintaining high acceleration efficiency. During the striking phase, the spring mass Ms is released and added to the striking element, increasing the striking force to (m+Ms)v without requiring the magnetic field to accelerate the full mass, thus resolving the contradiction between striking force and acceleration efficiency
4Use of energy by moving object
If the spring element is compressed during acceleration, then energy storage is improved, but the spring force may interfere with magnetic field acceleration
Solution Approach 1:
The spring element operates in periodic cycles, being compressed during the acceleration phase and then releasing its stored energy during the striking phase. This periodic action ensures that the spring force acts in the desired direction at the right time, storing energy during acceleration without interfering with the magnetic field acceleration, and then releasing that energy during the striking phase to augment the impact force
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 mechanism achieves a higher striking force and more efficient energy utilization by leveraging the spring element to augment magnetic field acceleration, resulting in improved control and power delivery.
Implementation Method 1
A spring element is provided which exerts a force on the striking element in every position in the working space in the direction of the anvil. The spring element is correspondingly biased during the movement away from the anvil.
Implementation Method 2
The striking mechanisms based on the direct acceleration of a striking element by means of magnetic fields have the advantage of a greater degree of control of the striking behavior
