Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional linear hydraulic rams are used for compaction, then waste compaction is achieved, but the collection bin occupies excessive space and available volume is reduced
Solution Approach 1:
The actuator is positioned within the cavity of the collection bin, nesting the compaction mechanism inside the existing volume rather than adding it externally. This allows the compaction system to be contained within the bin's internal space, maximizing the use of available volume while maintaining compaction capability.
Solution Approach 2:
The invention transitions from linear hydraulic rams to a rotational actuator mechanism that moves the compression platen along a curved path. This dimensional change from linear to rotational motion allows the compiction mechanism to operate within a compact footprint, preserving more of the collection bin's usable volume.
2Quantity of substance
If conventional linear hydraulic rams are used for compaction, then waste compaction is achieved, but the collection bin requires additional external space which is not always practical
Solution Approach 1:
The actuator and compression platen are nested within the cavity of the collection bin, eliminating the need for external compaction equipment. This nesting approach ensures that the overall dimensions of the collection bin remain unchanged while achieving effective waste compaction internally.
Solution Approach 2:
By using rotational motion instead of linear extension, the compaction mechanism achieves the same compaction effect without requiring additional length or external space, thus maintaining practical collection bin dimensions for handling by transport vehicles.
3Quantity of substance
If conventional compaction systems are used, then waste compaction is achieved, but significant power is required which is limited in many applications
Solution Approach 1:
The actuator operates in periodic cycles, rotating to compress the waste and then returning to its initial position. This periodic operation allows the system to achieve compaction over time with lower instantaneous power requirements compared to continuous linear hydraulic systems, making it suitable for applications with limited power availability.
