Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the fixation frame and moveable frame are assembled by welding to achieve structural stability, then the structural stability is improved, but the packing volume increases and transportation becomes difficult
Solution Approach 1:
The bed frame is divided into separate fixation frame and moveable frame components that can be detached from each other. The moveable frame can be dismantled into smaller parts (including the actuator assembly) that fit within the fixation frame's storage space, reducing packing volume while maintaining structural integrity when assembled.
Solution Approach 2:
The moveable frame components, particularly the actuator assembly, are designed to nest within the fixation frame when dismantled. The actuator fits inside the fixation frame's hollow structure, and the moveable frame's longitudinal and transverse rods can be positioned within the fixation frame's boundaries, minimizing overall packing volume.
2Stability of the object's composition
If the bed frame is designed as a non-dismantable welded structure to ensure stability, then the structural stability is improved, but the ease of assembly deteriorates requiring professional assembly
Solution Approach 1:
The bed frame is segmented into modular components (fixation frame, moveable frame, actuator) connected through detachable joints. These joints use simple insertion and locking mechanisms that allow users to assemble and disassemble the frame without specialized tools or skills, while welded sections maintain structural stability where required.
Solution Approach 2:
Detachable connection joints serve as intermediaries between the fixation frame and moveable frame. These joints incorporate guiding structures and locking mechanisms that simplify the assembly process, allowing users to easily connect components while ensuring stable load transmission during use.
3Stability of the object's composition
If the moveable frame is designed as a single integrated structure to maintain stability, then the structural stability is improved, but the packing volume increases reducing transportation convenience
Solution Approach 1:
The moveable frame is divided into separate longitudinal rods, transverse rod, and actuator components. These segmented parts can be independently positioned and stored within the fixation frame's hollow space, significantly reducing packing volume while maintaining the structural stability of the complete moveable frame when reassembled.

AI summary
A dismantlable electric bed includes a fixation frame, a moveable frame, and an actuator. The moveable frame includes two longitudinal rods and a transverse rod having two ends. The two longitudinal rods are pivotally connected with the fixation frame, respectively. Each longitudinal rod has at least one insertion hole. Each end of the transverse rod is provided with at least one post detachably inserted into the at least one insertion hole of one longitudinal rod. The actuator has two ends pivotally connected with the fixation frame and the transverse rod, respectively. As such, the electric bed is dismantlable to reduce the packing volume thereof and convenient to be assembled by the user herself/himself.
