Hook-Shaped Bed Frame Connector for Tool-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed assembly and disassembly processes are inefficient, requiring significant time and effort, and pose logistical challenges due to large and heavy components, as well as risks associated with screw connections that can be over- or under-tightened, leading to loose or damaged connections.
Innovation Solution
A bed design featuring detachable hook-shaped connecting parts that engage with the bed frame without screws, providing vertical and transverse offsets for rigidity, and a clamping mechanism with a defined stop position to ensure secure attachment and easy assembly/disassembly, using a resilient means for closure and frictional forces for secure holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw connections are used to attach safety sides and panels to the bed frame, then the connection can be secured, but the assembly process requires a great deal of time and the risk of over- or under-tightening exists
Solution Approach 1:
The patent replaces the screw connection system with a hook-shaped engaging portion system. Instead of using threads and tightening torques, the invention uses geometric interlocking through hooks that engage with corresponding openings in the bed frame, eliminating the need for rotational fastening operations and associated time consumption.
Solution Approach 2:
The hook-shaped connecting parts are designed to automatically engage with the bed frame openings and secure themselves without requiring external tightening tools or operations. The connection mechanism self-secures through the geometric configuration of the hooks and openings, eliminating the need for manual tightening force application.
2Reliability
If screw connections are used to attach safety sides and panels to the bed frame, then the connection can be secured, but the risk of over- or under-tightening can lead to loose or crushed components
Solution Approach 1:
The patent replaces the screw connection system with a hook-shaped engaging portion system. Instead of using threads and tightening torques, the invention uses geometric interlocking through hooks that engage with corresponding openings in the bed frame, eliminating the need for rotational fastening operations and associated time consumption.
Solution Approach 2:
The hook-shaped connecting parts are designed to automatically engage with the bed frame openings and secure themselves without requiring external tightening tools or operations. The connection mechanism self-secures through the geometric configuration of the hooks and openings, eliminating the need for manual tightening force application.
3Productivity
If large and heavy assemblies are preassembled in larger units/modules, then fewer connections are needed, but the logistical flexibility is restricted and the effort to provide different variants is significantly increased
Solution Approach 1:
The patent divides the bed structure into modular components (side elements, safety sides, panels, head and foot parts) that can be independently manufactured and assembled. Each component has standardized hook-shaped connecting parts that can be quickly attached or detached from the bed frame, enabling flexible configuration and easy replacement of individual modules without handling large heavy assemblies.
4Volume of moving object
If the bed is designed for quick disassembly to save space in hospitals and nursing homes, then storage efficiency is improved, but the connection must still be secure during use
Solution Approach 1:
The patent employs a dynamic connection system where the holder can transition between a closed secured state (during use) and an open detached state (for storage). The holder covers the engagement elements and prevents accidental disengagement during normal use, but can be manually opened to allow quick removal of components for compact storage when not in use.
