Assembly device for a table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional table assembly devices have protruding eccentric portions that increase volume and weight, making them inconvenient to store and carry, and require costly embedded engaging panels that complicate assembly and disassembly.
Innovation Solution
An assembly device with an assembling mount and engaging elements featuring a connecting portion and engaging portion, utilizing elastic engaging segments and head segments to securely hold the table board to the mounting frame, allowing easy assembly and disassembly without protrusions and embedded panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an eccentric portion is protruded from the external surface of the assembling mount body, then the assembling effect is achieved, but the overall volume and weight increase
Solution Approach 1:
The patent extracts the protruding eccentric portion from the assembling mount body and replaces it with a recessed eccentric portion. This removes the harmful protrusion that increases volume and weight while retaining the essential assembling function through the recessed design that still provides the necessary offset for engagement.
Solution Approach 2:
The patent inverts the conventional design by making the eccentric portion recessed rather than protruding. This inversion maintains the functional advantage of the eccentric mechanism for reliable assembly while eliminating the disadvantage of increased volume and weight associated with protruding structures.
2Reliability
If an engaging panel is embedded in the table board, then the locking effect is achieved, but the cost and weight increase
Solution Approach 1:
The patent extracts the embedded engaging panel from the table board and relocates the engagement function to the assembling mount itself. The recessed eccentric portion on the assembling mount directly engages with the table board without requiring a separate embedded panel, thereby reducing weight and cost while maintaining the locking effect.
Solution Approach 2:
The patent merges the engaging panel function into the assembling mount structure. The recessed eccentric portion integrates the engagement functionality that was previously separated as an embedded panel, reducing the total number of components and the overall weight of the table board assembly.
3Ease of operation
If the table board is displaced or deflected relative to the mounting frame, then the structural relationship is affected, but the twist-locking rod cannot rotate easily to disassemble
Solution Approach 1:
The patent changes the geometric parameters of the engagement interface by using a recessed eccentric portion with specific dimensional relationships. The recessed design provides adequate clearance and alignment tolerance that maintains the structural relationship even when the table board is displaced or deflected, allowing the twist-locking rod to rotate easily for disassembly.
4Ease of operation
If a protruding eccentric portion is used, then the assembling function is provided, but the volume increases making storage and carrying inconvenient
Solution Approach 1:
The patent extracts the protruding eccentric portion that increases volume and replaces it with a recessed design. This reduces the overall volume of the assembling mount, making the table more compact and convenient for storage and carrying while maintaining the assembling function.
Solution Approach 2:
The patent inverts the conventional protruding design to a recessed design. This inversion reduces the external dimensions and volume of the assembling mount, improving portability and storage convenience without sacrificing the essential assembling capability.
