Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bed frames are bulky, costly to transport, inconvenient to assemble and disassemble, and pose safety hazards due to inadequate lifting forces and rapid closing speeds, leading to potential injuries and accidents.
Innovation Solution
A novel detachable bed frame assembly mechanism featuring a rectangular frame with L-shaped iron connectors, wooden strips, and a flip link mechanism with a pneumatic rod and booster tension spring, which allows for easy disassembly, increased load-bearing capacity, and safer operation by controlling the lifting and closing forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bed frames are made detachable for easy transportation, then transportation convenience is improved, but load-bearing capability deteriorates
Solution Approach 1:
The bed frame is divided into multiple detachable modules including head board, foot board, side rails, and cross members that can be separated into smaller components for easy transportation and reassembled to provide adequate load-bearing support when needed
Solution Approach 2:
The detachable components are designed to nest within each other during storage and transportation, with smaller parts fitting into larger structural elements, reducing overall volume while maintaining structural integrity when assembled
2Force
If pneumatic rod with large force value is used for opening, then opening capability is improved, but safety deteriorates due to bouncing and injury hazard
Solution Approach 1:
A tension spring is pre-installed to provide initial boosting force during the opening process, allowing the use of a pneumatic rod with smaller force value that operates more safely without causing bouncing or injury hazards
Solution Approach 2:
The system transitions from using a high-force pneumatic rod alone to a combined system where the tension spring provides force during the critical initial opening phase, changing the force parameters to achieve safe operation
3Power
If pneumatic rod force increases with angle, then opening capability is improved, but safety deteriorates due to rapid closing speed squeezing fingers
Solution Approach 1:
The tension spring is pre-configured to provide counteracting force during the closing process, compensating for the rapid closing speed generated by the pneumatic rod and preventing finger squeezing hazards
4Strength
If bed frame is made bulky for strength, then load-bearing capability is improved, but transportation cost deteriorates
Solution Approach 1:
The bed frame is segmented into multiple components that can be collapsed and nested together, dramatically reducing packaging volume while maintaining adequate load-bearing capability when assembled through proper connection mechanisms

AI summary
The present invention relates to the field of bed frame structures, and in particular, to a novel detachable bed frame assembly mechanism. The novel detachable bed frame assembly mechanism includes a bed frame body. The bed frame body includes an outer frame, an inner frame, and two sets of wooden strips. The outer frame is a rectangular frame including two horizontal tubes, two lateral tubes, four L-shaped iron-plate connectors, bolts, and nuts. The inner frame includes at least one horizontal connecting tube, a plurality of lateral connecting tubes, iron sheets, bolts, and nuts. The two sets of wooden strips are symmetrically disposed on the horizontal connecting tube and the horizontal tubes on both sides of the horizontal connecting tube and are parallel to the lateral tubes, to connect the horizontal connecting tube to the horizontal tubes. The invention is easy to assemble and disassemble and is safe and reliable.
