Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple roller bases are connected one by one to form a movable display device, then the display device can accommodate products of various sizes, but the assembly time increases and work efficiency decreases
Solution Approach 1:
The roller base is divided into multiple unit columns (first unit column, second unit column, etc.) that can be independently manufactured and then quickly connected through coupling parts. This segmentation allows for modular assembly, reducing the time required to assemble the complete roller base while maintaining adaptability to different product sizes by selecting appropriate numbers and configurations of unit columns.
Solution Approach 2:
The coupling parts are pre-formed and integrated into the unit columns during manufacturing, so that when assembly is required, the unit columns can be directly connected without additional alignment or fastening operations. This preliminary preparation of connection interfaces significantly reduces assembly time while preserving the versatility of the modular structure.
2Stability of the object's composition
If multiple roller bases are connected via frame rails, then the structural integrity is maintained, but friction between products and frame rails increases
Solution Approach 1:
The frame rail connection system is extracted and replaced with a direct coupling mechanism between unit columns. The coupling parts include coupling protrusions and coupling grooves that enable unit columns to connect directly to each other, eliminating the need for separate frame rails that caused friction with moving products.
Solution Approach 2:
The coupling parts act as intermediary elements between unit columns, providing a frictionless connection mechanism. The coupling protrusions fit into coupling grooves to create stable joints without requiring external frame rails, thereby maintaining structural integrity while preventing friction-induced interference with product movement.
3Manufacturing precision
If roller bases are aligned and coupled manually, then precise positioning is achieved, but the manufacturing complexity and labor requirements increase
Solution Approach 1:
The coupling parts feature asymmetric geometries with coupling protrusions on one unit column matching complementary coupling grooves on adjacent unit columns. This asymmetric design provides self-aligning characteristics that guide precise positioning during assembly, eliminating the need for complex alignment procedures while maintaining manufacturing precision.
4Device complexity
If a single-column roller base structure is used, then the structure is simple, but more friction occurs between products and frame rails
Solution Approach 1:
The unit columns are merged into a single integrated roller base structure through direct coupling, eliminating the need for separate frame rails. This merging maintains the simplicity of the overall structure while removing the friction-causing frame rail components, as the coupled unit columns provide both structural support and frictionless product movement surfaces.
