Convertible table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tables lack height adjustability, making them inconvenient for people of different heights and not adaptable to various applications.
Innovation Solution
A convertible table with a table converting mechanism that allows the height to be adjusted by rotating a shaft to slide supporting legs in leg mounting tracks, enabling transformation between multiple height positions, such as from a dining table to a coffee table height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the table height is fixed, then the structure is simple and stable, but it cannot accommodate different users and applications
Solution Approach 1:
The patent applies the dynamics principle by transforming the static table leg structure into a dynamic, adjustable system. The legs incorporate sliding mechanisms with tracks and carriages that allow the leg length to be changed from fixed to variable, enabling the table to adapt to different heights while maintaining structural integrity through engineered connection points and locking features.
Solution Approach 2:
The patent applies segmentation by dividing each leg into multiple segments or sections that can slide relative to each other. The leg structure is broken down into a main body and an adjustable portion that can move along guided tracks, allowing independent adjustment of leg length while keeping the overall table structure unified and stable.
2Ease of operation
If the table height is adjusted manually without mechanism, then the structure remains simple, but the adjustment process is time-consuming and inconvenient
Solution Approach 1:
The patent implements dynamics by introducing a crank and connecting rod mechanism that converts rotational motion into linear sliding motion of the legs. This dynamic mechanism allows users to adjust the table height easily by turning a hand crank, transforming a potentially complex adjustment task into a simple rotational operation that drives the leg carriages along their tracks.
Solution Approach 2:
The patent uses an intermediary mechanism (the crank-connecting rod system) to mediate between the user's input (rotational force on the crank) and the desired output (linear movement of the legs). This intermediary mechanism simplifies the adjustment operation by providing mechanical advantage and guiding the movement through defined paths, making the adjustment process user-friendly despite the underlying mechanical complexity.
3Adaptability or versatility
If multiple leg positions are available, then the table can serve various functions, but the leg mounting structure becomes more complex
Solution Approach 1:
The patent applies universality by designing a single, integrated leg adjustment mechanism that provides multiple height positions and serves various table functions (dining table, coffee table, desk, etc.). Rather than creating separate mounting structures for each height position, the universal sliding mechanism with tracked carriages allows the same structure to accommodate multiple positions and applications, reducing overall structural complexity while maximizing versatility.
Solution Approach 2:
The patent uses dynamics to create a continuously adjustable leg length system rather than discrete fixed positions. The sliding mechanism with guides and carriages allows smooth variation of leg length across a range of positions, enabling the table to adapt to different functions dynamically. This dynamic approach replaces multiple static mounting structures with a single flexible system.
