Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional mounting device is used to mount a ring on an injector, then the ring can be mounted, but the device is cumbersome and energy-intensive
Solution Approach 1:
The mounting device is segmented into a hollow tube, a pusher member, and an actuating element that can be independently assembled and disassembled. This modular structure reduces overall device complexity while maintaining mounting functionality, allowing each component to perform its specific function efficiently.
Solution Approach 2:
The invention extracts the essential mounting function from complex traditional devices, retaining only the critical components (hollow tube, pusher member, actuating element) needed to mount the ring. This simplification reduces device complexity while preserving the core mounting capability.
2Ease of operation
If a traditional mounting device is used to mount a ring on an injector, then the ring can be mounted, but it consumes excessive energy
Solution Approach 1:
The pusher member acts as an intermediary between the actuating element and the ring. It translates the actuating element's motion into controlled linear movement that pushes the ring onto the injector, reducing the direct energy required from the operator while maintaining effective mounting force.
Solution Approach 2:
The invention replaces direct manual mechanical force with a mechanical advantage system using the actuating element and pusher member. This substitution reduces the energy input required from the operator while achieving the same mounting result.
3Manufacturing precision
If force is applied to mount the ring, then the ring can be positioned, but uneven force application causes deformation or tilting
Solution Approach 1:
The pusher member is designed to distribute force locally and uniformly across the ring's surface. This localized uniform force application prevents deformation and tilting while achieving precise placement, resolving the contradiction between placement precision and ease of force application.
4Manufacturing precision
If the mounting device is fixed for specific diameters, then it can provide precise mounting, but it cannot adapt to injectors and rings of different diameters
Solution Approach 1:
The hollow tube and pusher member are designed with dynamic adjustability, allowing the device to adapt to different injector and ring diameters. This dynamic configuration maintains mounting precision across various sizes while providing versatility, resolving the contradiction between precision and adaptability.
5Ease of operation
If the actuating element can be freely actuated, then operation is simple, but accidental actuation can cause the ring to fly off uncontrollably
Solution Approach 1:
The device incorporates a preliminary safety mechanism that prevents accidental actuation before the ring is properly positioned. This preliminary anti-action ensures safety while maintaining operational simplicity, resolving the contradiction between ease of operation and reliability.
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
Facilitates easy and secure mounting of rings on injectors with reduced energy consumption and adaptability to different diameters, ensuring precise placement and preventing ring deformation or unintended movement.
Implementation Method 1
the actuating element is designed as a lever-shaped actuating element. With the help of a lever-shaped actuating element, the pushing element can be moved in a particularly energy-saving manner by using the leverage effect.
