Solution Overview

Problem

Existing folding table designs with removable legs face challenges in supporting the stability of large and heavy work surfaces, as simple elastic bands are inadequate for ensuring a firm and reliable disassembly and repositioning of legs against the tabletop, limiting their adaptability to larger tables.

Innovation Solution

The use of securing clips with rigid profiles that hold each foot against the tabletop in both working and compact configurations, which also function as cable supports, optimizing part functionality and reducing waste for recycling, while ensuring stability and adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If simple elastic bands are used to hold legs against the tabletop in compact configuration, then the device complexity is reduced, but the reliability of holding heavy legs is insufficient

Engineering Contradiction:
Improvefastening mechanism complexityVSAvoidleg holding reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent combines the fastening function and cable support function into a single integrated structure (the bracket). The bracket includes both the securing elements (clips, screws, or other fastening mechanisms) and the cable support features (guides, channels, or attachment points), thereby reducing the number of separate parts while maintaining both functions reliably

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bracket is designed as a multi-functional component that simultaneously serves as a leg support structure, a fastening mechanism for securing legs in compact configuration, and a cable management system. This universal design allows one component to perform multiple functions that would traditionally require separate elements

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate cable support elements are added to the fastening mechanism, then the cable management function is improved, but the number of parts increases and waste is generated

Engineering Contradiction:
Improvecable management capabilityVSAvoidnumber of parts
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent integrates cable support features directly into the bracket structure itself, eliminating the need for separate cable management components. The bracket incorporates guides, channels, or attachment points for cables as inherent parts of its design, thereby adding functionality without increasing part quantity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bracket is designed as a universal component that handles both leg support and cable management functions. By making the bracket multi-functional, the patent avoids the need for additional dedicated cable support elements, reducing the total number of parts while enhancing versatility

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Strength

If the bracket structure is made more robust to support heavy legs, then the strength is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvebracket load-bearing capacityVSAvoidbracket manufacturing simplicity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The bracket is designed with a modular structure that can be manufactured using standard fabrication processes. The segmentation allows for efficient manufacturing while maintaining structural integrity, enabling the bracket to bear heavy loads without requiring overly complex or custom manufacturing methods

Inventive Principle:
Principle #1Segmentation

AI summary

Item of furniture whose component parts comprise a table top (1), at least two legs (2), and means for attaching the legs (2) to the table top (1), said components being either in a working configuration in which the legs (2) are attached perpendicularly to the table top (1), or in a compact configuration in which the fixing brackets (6) lock said legs (2) parallel to and in contact with the table top (1). Each leg (2) is held against the table top (1) by at least two fixing brackets (6) in the compact configuration. The brackets (6) are arranged relative to each other and configured in such a way as together to form at least one cable guide (7) in the working configuration.
