Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a spring mechanism is used to store and release energy, then the device can transfer energy to the fastening element, but the energy transfer is limited to a fixed upper limit and cannot be adjusted for different fastening elements and substrates
Solution Approach 1:
The patent applies dynamics by replacing the fixed spring mechanism with an adjustable energy storage system. The energy storage device can be charged to different energy levels, and the energy transfer amount is dynamically adjustable through the energy transfer mechanism, allowing adaptation to different fastening elements and substrate types while overcoming the fixed energy limit of spring-based systems.
Solution Approach 2:
The patent implements parameter changes by enabling adjustment of energy transfer parameters. The energy storage device can store varying amounts of energy, and the energy transfer mechanism can control the transfer amount, allowing the system to adapt to different application requirements by changing energy parameters rather than being constrained to a single fixed energy level.
2Adaptability or versatility
If the spring outputs tension energy as an impulse, then the piston can be accelerated onto the fastening element, but the device cannot be used universally for all fastening elements and substrates
Solution Approach 1:
The patent achieves universality by designing an energy transfer system that can adapt to different fastening elements and substrates. The energy storage device combined with the energy transfer mechanism provides a multi-functional system that can deliver appropriate energy levels for various applications, replacing the single-purpose spring mechanism with a versatile adjustable system.
Solution Approach 2:
The system uses dynamic energy adjustment capability to achieve universal applicability. The energy transfer mechanism can be configured to provide different energy outputs based on the specific requirements of the fastening element and substrate combination, allowing the same device to universally handle diverse applications through dynamic parameter adjustment.
3Use of energy by moving object
If the mechanical-energy storage device stores and outputs energy, then sufficient energy can be transferred to the fastening element, but the energy-transfer element cannot be moved into the setting position without discharging the energy storage device
Solution Approach 1:
The patent applies segmentation by separating the energy storage function from the energy transfer function. The energy storage device can be charged independently, and the energy transfer mechanism can be actuated independently to move the energy transfer element. This segmentation allows the energy storage device to be recharged without requiring the energy transfer element to be in the setting position, improving operational independence.
Solution Approach 2:
The system implements preliminary action by allowing the energy storage device to be charged in advance, independent of the energy transfer operation. The energy can be stored beforehand, and when needed, the energy transfer mechanism can be actuated to move the energy transfer element to the setting position and discharge the stored energy, enabling preparatory energy storage without coupling to the transfer operation.
