Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture frames, particularly bedroom beds, are cumbersome to install due to numerous bolt and nut parts, which can damage the wooden structure and require labor-intensive assembly, and are difficult to reuse for different furniture pieces.
Innovation Solution
A frame structure comprising outer frames, lateral rods, and connecting members that allow for flexible assembly and adjustment of dimensions through movable inner and outer tubes, clamping members, and adjustable connecting members, enabling easy assembly and reconfiguration into various furniture pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bolts and nuts are used to connect furniture frames, then the connection strength is improved, but the assembly complexity and time consumption increase significantly
Solution Approach 1:
The connecting member is divided into multiple functional segments: a first connecting end for joining to the frame, a second connecting end for joining to the board, and a rotating middle section. This segmentation allows each part to perform its specific function independently, simplifying the overall assembly process while maintaining connection strength.
Solution Approach 2:
The patent extracts and eliminates the need for separate nuts and multiple bolts by integrating all connection functions into a single connecting member. This extraction of unnecessary components directly reduces assembly complexity while the remaining integrated component maintains sufficient connection strength through its specialized design.
2Reliability
If multiple bolts and nuts are used for assembly, then the connection reliability is improved, but the installation time and labor intensity increase
Solution Approach 1:
The patent merges the functions of multiple bolts and nuts into a single integrated connecting member. This connecting member simultaneously provides multiple connection points and secure fastening in one piece, maintaining connection reliability while dramatically reducing the number of components that need to be handled and installed.
Solution Approach 2:
The connecting member is pre-designed and pre-assembled as an integrated unit during manufacturing, with the first connecting end, second connecting end, and rotating section already configured. This preliminary action eliminates the need for on-site assembly of multiple separate fasteners, reducing installation time while ensuring reliable connections through the pre-engineered design.
3Strength
If screws are tightened fully to ensure secure connection, then the connection strength is improved, but the rotation stroke required increases installation time
Solution Approach 1:
The rotating section of the connecting member introduces dynamic adaptability to the connection system. This rotating mechanism allows the connecting member to self-adjust and lock into position through rotational movement, achieving secure connection without requiring lengthy tightening strokes. The dynamic rotating action replaces the static, time-consuming full-tightening process of traditional screws.
4Manufacturing precision
If furniture frames are designed with fixed dimensions, then the manufacturing precision is improved, but the adaptability to different furniture types decreases
Solution Approach 1:
The rotating section enables the connecting member to adapt to different angular positions and orientations, allowing the same connecting member to be used in various furniture configurations. This dynamic rotational capability maintains manufacturing precision for each individual connection while providing versatility across different furniture types and arrangements.
Solution Approach 2:
The connecting member is designed as a universal component that can serve multiple furniture types and configurations. The first connecting end can attach to different frame structures, the second connecting end can secure various board types, and the rotating section accommodates different angular requirements, making a single component design applicable across diverse furniture applications.

AI summary
A frame structure comprises a first outer frame, a second outer frame, at least two lateral rods, and a lateral rod clamping member. A plurality of connecting members are respectively separably connected to the first outer frame, the at least two lateral rods, and the second outer frame. The first outer frame and the second outer frame each comprise an inner tube, an outer tube, and an adjustment member for adjusting a relative position of the inner tube and the outer tube. Each of the at least two lateral rods comprises an inner rod and an outer rod. The lateral rod clamping member enables part or all of the at least two lateral rods to be connected together.
