Solution Overview

Problem

Existing table designs, particularly office tables, often require changes to adapt to new office furnishings or to enhance visual appeal and corporate identity, but existing solutions are not cost-effective or simple to implement.

Innovation Solution

A retrofit cover for table legs featuring two retaining profiles and cladding elements that form a jacket around the leg, allowing for easy and inexpensive design changes using various cladding materials and attachment methods like clips, magnets, or screws.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If table design is changed to adapt to new office furnishings or corporate identity, then visual appeal and adaptability are improved, but manufacturing cost and complexity increase

Engineering Contradiction:
Improvedesign adaptabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The table leg is divided into two independent parts: the original table leg structure and the separate cladding element. The cladding element can be manufactured independently and attached later, allowing design changes without modifying the entire table leg. This segmentation enables cost-effective design adaptations by only manufacturing and replacing the cladding portion rather than the entire leg assembly.

Inventive Principle:
Principle #1Segmentation

2Strength

If traditional fastening methods are used to attach cladding elements, then connection strength is improved, but assembly complexity and time increase

Engineering Contradiction:
Improveconnection strengthVSAvoidassembly simplicity
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical fastening systems (screws, bolts, rivets) with a friction-based insertion system. The cladding element features an insertion end that is pushed into a receiving cavity, creating a secure connection through friction and geometric interlocking rather than mechanical fasteners. This substitution maintains connection strength while dramatically simplifying assembly to a tool-free, single-action operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If cladding elements require separate fasteners, then connection reliability is improved, but device complexity increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidfastening system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fastening function is merged into the cladding element itself. The insertion end and receiving cavity are integrated features of the cladding element and table leg structure, eliminating the need for separate fasteners. This merging maintains connection reliability through the friction-fit and geometric interlocking mechanisms while reducing the overall fastening system complexity to a single integrated component design.

Inventive Principle:
Principle #5Merging (Combining)

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 frequent and cost-effective design modifications of table legs, enhancing visual appeal and corporate identity without the need for separate fasteners, offering a versatile and tool-free assembly option.

Implementation Method 1

A very simple and quick attachment option is obtained if the holding profiles can be attached to the table leg using a clip system, a Velcro connection or magnets

AI summary

Two u-shaped aluminum profiles (7) are attached to the lateral edges of the stands (2) carrying the tabletop (1) of a conference table or the desktop of a desk and locked with suitable fastening elements. A rectangular panel (8) in a color or pattern matching the design of the remaining furniture or a specific company color scheme is attached to the profiles (7) covering the original stand (2). The panels (8) can be made of a thin layer of wood, metal, or plastic.
