Solution Overview

Problem

Conventional bar counters are expensive, heavy, and difficult to dismantle, making them unsuitable for private use due to space constraints and limited mobility.

Innovation Solution

A bar counter design featuring a lightweight construction with inner and outer plastic plates connected via connecting elements, allowing for increased stability and ease of assembly/disassembly, using a twin-sheet method for efficient production and incorporating molded stiffening elements for enhanced stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional heavy materials are used for bar counters, then durability and solid impression are improved, but cost and weight increase significantly

Engineering Contradiction:
ImprovedurabilityVSAvoidweight
Core Design Contradiction:
ReliabilityVSWeight of stationary object

Solution Approach 1:

The bar counter combines plastic material for the frame structure with glass or plastic panels for surfaces, creating a composite construction that achieves durability through design rather than material mass. The plastic frame provides structural integrity while being significantly lighter than traditional materials like stainless steel or wood.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent uses thin plastic panels (2-5mm thickness) and glass panels as surface materials that provide the necessary durability and aesthetic appearance without requiring thick, heavy construction. The panels are mounted on a lightweight plastic frame that supports them effectively.

Inventive Principle:
Principle #30Flexible shells and thin films

2Strength

If conventional solid frame construction is used, then structural strength is improved, but ease of dismantling deteriorates

Engineering Contradiction:
Improvestructural strengthVSAvoidease of dismantling
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The bar counter is divided into modular components: a plastic frame structure, removable panels (glass or plastic), and separate functional elements like taps and lighting. This segmentation allows the counter to be disassembled into manageable parts for easy transport and reassembly, while each component maintains its structural integrity when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection elements are designed to provide stable, adjustable, and reversible connections. The frame structure allows for flexible assembly and disassembly while maintaining structural strength during use, enabling the counter to transition between stable operational state and easily dismantled state.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If conventional heavy construction is used, then stability is improved, but adaptability for mobile use deteriorates

Engineering Contradiction:
ImprovestabilityVSAvoidadaptability for mobile use
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The combination of plastic frame material with rigid panels creates a structure that is lightweight enough for mobility yet stable during use. The plastic material provides sufficient structural rigidity when properly designed, eliminating the need for heavy materials to achieve stability.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The modular design with separate frame and panel components allows the bar counter to be easily transported by disassembling into lighter parts, then quickly reassembled to provide stable operation. The connecting elements ensure stability when assembled while enabling easy disassembly for mobile applications.

Inventive Principle:
Principle #1Segmentation

4Weight of stationary object

If lightweight plastic panels are used, then weight and ease of dismantling are improved, but structural stability deteriorates

Engineering Contradiction:
ImproveweightVSAvoidstructural stability
Core Design Contradiction:
Weight of stationary objectVSStrength

Solution Approach 1:

The plastic frame structure is designed with optimized geometry and thickness to provide sufficient structural strength despite using lightweight plastic material. The frame acts as a rigid support structure that stabilizes the lightweight panels, creating a composite system where the frame compensates for the lower strength of the panel materials.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

Thin plastic panels (2-5mm) are used as surface materials that provide the necessary structural stability when properly supported by the frame. The panels are designed with appropriate thickness and mounting arrangements to prevent deformation while keeping the overall structure lightweight.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

The counter has a cover wall (20), a front side wall (50) and a lateral side wall (70), where one of the walls exhibits an inner plate and an outer plate. The outer plate is arranged parallel at a distance to the inner plate, where the outer plate is sectionally connected with the inner plate. A hollow space is formed between the inner plate and the outer plate. The hollow space extends in a region of a vertically running edge of the side wall. The inner plate and the outer plate are welded with each other. A base wall (30) is completely made of plastic.
