Inserting assembled bedstead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembled bedsteads require additional tools for assembly, leading to inconvenient and unstable installation, with issues of bolts not being tightened properly causing instability and noise during use.
Innovation Solution
An inserting assembled bedstead design featuring inserting pieces and sleeve pieces that allow for tool-free assembly and disassembly, using a cooperation structure to ensure stability and secure connection without bolts, with inclined guide and pressing boards for vertical force distribution and deformation adaptation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bolts and additional tools are used for assembly, then the connection strength is improved, but the ease of operation deteriorates due to requiring additional tools and complex assembly process
Solution Approach 1:
The patent extracts and removes the bolts and additional fastening tools from the assembly system, replacing them with a pure insertion mechanism where components are joined simply by inserting one part into another without any additional fastening elements
Solution Approach 2:
The inserting pieces and sleeve pieces are designed to self-lock and self-stabilize through their geometric shapes and fitted connections, eliminating the need for external tools or additional fastening operations to secure the assembly
2Stability of the object's composition
If bolts are used for assembly, then the initial connection stability is improved, but the reliability deteriorates when bolts are not tightened properly causing instability and noise
Solution Approach 1:
The insertion mechanism automatically achieves stable connection through the fitted geometry of inserting pieces and sleeve pieces, with no manual tightening required. The connection self-regulates to eliminate gaps and prevent noise without relying on operator skill or tool precision
Solution Approach 2:
Instead of using bolts that require tightening to achieve stability, the patent inverts the approach by using insertion where the act of insertion itself creates the stable connection through friction and geometric interlocking, eliminating the tightening step entirely
3Ease of operation
If the bedstead is disassembled and folded for storage, then the ease of operation is improved, but the volume increases due to requiring multiple components
Solution Approach 1:
The patent applies nesting by allowing disassembled bedstead components to be stored within the hollow spaces of the bedstead frame itself, with inserting pieces and longitudinal pieces fitting inside the tubular structures, thereby reducing external storage volume requirements
