Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thread-like jets at high pressure are used, then washing effectiveness is improved, but grooves or incisions are created on the container wall
Solution Approach 1:
The patent changes the jet geometry parameters from thread-like to triangular cross-section with a specific opening angle (40-80 degrees). This parameter change distributes the washing action over a broader area, reducing pressure density while maintaining total washing effectiveness, thereby preventing grooves and incisions on the container wall.
Solution Approach 2:
The triangular jet shape creates a localized broad-contact area that distributes washing force uniformly across the container surface. This local quality change ensures effective washing without concentrating force that would cause damage, resolving the contradiction between washing effectiveness and container integrity.
2Area of stationary object
If rotating washing head with two axes is used, then coverage of side walls is improved, but washing cycle duration increases
Solution Approach 1:
The patent employs a helical trajectory for the triangular jet that follows a curved path along the container wall. This curved washing pattern naturally covers the cylindrical surface area efficiently, achieving comprehensive side wall coverage without requiring complex multi-axis rotation mechanisms, thus reducing washing cycle duration.
Solution Approach 2:
The washing system uses dynamic movement along a helical path rather than static multi-axis rotation. This dynamic approach allows continuous coverage of the container surface in a single pass, improving efficiency and reducing the number of rotation cycles needed to wash the entire side wall.
3Reliability
If high pressure jets are used, then washing action is improved, but pump size and power consumption increase
Solution Approach 1:
The patent changes the jet parameters from high-pressure thread-like jets to lower-pressure triangular jets with broader contact area. This parameter change maintains washing effectiveness through increased contact area rather than increased pressure, thereby reducing pump power requirements and allowing the use of smaller, less expensive pumping equipment.
4Area of stationary object
If vertical stroke mechanism is added, then coverage of entire inner surface is improved, but device complexity and cost increase
Solution Approach 1:
The helical trajectory of the triangular jet naturally covers the entire inner surface of the cylindrical container through its curved path. This geometric approach to coverage eliminates the need for additional vertical stroke mechanisms, reducing device complexity and avoiding the costs and regulatory complications associated with electric or pneumatic actuation systems.
