Adjustable bracket for furniture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable furniture, such as tables and chairs, typically lacks adaptability and versatility, as they are designed for a single mode of use and cannot adjust to varying needs or environments.
Innovation Solution
An adjustable bracket for furniture that includes a base with pivotally connected support members, featuring a central channel with a screw and hemispherical nut system, allowing for adjustable leg deployment angles through a knob mechanism, along with elastic members for smooth height adjustment and linkage between legs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If portable furniture is designed with fixed structure for simplicity, then manufacturing cost and device complexity are reduced, but adaptability and versatility are limited
Solution Approach 1:
The patent applies the dynamics principle by making the support members movable rather than fixed. The legs can be adjusted to different angles and positions through the screw-nut mechanism, allowing the furniture to adapt to various usage scenarios while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent implements universality by designing the bracket to perform multiple functions through adjustable support members. The same bracket structure can accommodate different leg configurations for various furniture types (tables, chairs, benches), enhancing versatility without requiring completely different designs for each application.
2Adaptability or versatility
If adjustable mechanisms are added to improve versatility, then adaptability is enhanced, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the adjustment mechanism into distinct modular components: support members, screws, nuts, and elastic members. Each component can be manufactured independently using standard machining processes, simplifying production while enabling complex adjustment functionality.
Solution Approach 2:
The patent uses a screw-nut mechanism as an intermediary between the user's manual input and the leg position adjustment. This simple mechanical intermediary translates rotational motion into linear displacement, enabling precise angle adjustment without requiring complex actuators or control systems.
3Adaptability or versatility
If multiple adjustment mechanisms are incorporated for height and angle control, then functional versatility is improved, but ease of operation deteriorates due to complexity
Solution Approach 1:
The patent merges the height adjustment and angle adjustment functions into a unified mechanism. By combining the screw-nut system with elastic members, the design achieves both vertical positioning and angular adjustment through a single integrated system, reducing the number of separate controls the user must manage.
Solution Approach 2:
The patent implements self-service through the elastic members that automatically maintain tension and return the support members to their neutral positions. The mechanism self-regulates without requiring additional springs, dampers, or control systems, simplifying operation while maintaining functional versatility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible deployment and height adjustment of furniture, enhancing usability and adaptability for different outdoor activities by allowing smooth changes in leg angles and height, thereby improving the versatility of portable furniture.
Implementation Method 1
the connection portion includes a first elastic member connected to the lower receiving portion and an end portion away from the mounting surface; the end portion abuts against an inner sidewall of the upper portion when the leg is in a folded position
Implementation Method 2
a screw passing through the central channel, and a knob disposed at a lower end of the screw; a sidewall of the central channel is arranged with threads that correspond to the screw
