Solution Overview

Problem

Existing desk frames require large storage space and high stockkeeping costs due to the need for prefabricated variants and sizes, limiting flexibility and increasing costs.

Innovation Solution

A telescopic desk frame design featuring longitudinally and transversely adjustable metal profile members that can be compactly packaged and assembled to various lengths, eliminating the need for transverse beam members and allowing for modular configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple prefabricated frame variants and sizes are manufactured to meet different table or desk requirements, then the adaptability and versatility of the frame system is improved, but the storage space required and stockkeeping costs increase significantly

Engineering Contradiction:

Improveframe configuration flexibilityVSAvoidstorage space for frames

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The frame is divided into separate modular components: a base frame unit and extendable profile members that can be attached as needed. This segmentation allows a single base frame to serve multiple size requirements by adding or removing profile members, eliminating the need to store multiple complete frame variants.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The frame system incorporates adjustable and extendable elements that allow the frame configuration to change dynamically based on requirements. The profile members can be extended or repositioned along the base frame to create different frame sizes and configurations from a single set of components.

Inventive Principle:

Principle #15Dynamics

2Stability of the object's composition

If transverse beam members are added to connect telescopic elements of lift columns, then the structural stability and stiffness of the frame is improved, but the leg room of the user is limited and device complexity increases

Engineering Contradiction:

Improveframe stabilityVSAvoiduser leg room

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The transverse beam members that were previously necessary for structural stability are removed from the design. Instead, the stability function is achieved through the engineered connection of the telescopic lift columns directly to the base frame, allowing the space beneath the desk to remain clear and unobstructed.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If multiple frame sizes and configurations are maintained in inventory to serve different table or desk top sizes, then the adaptability to various applications is improved, but the stockkeeping costs and storage requirements increase

Engineering Contradiction:

Improveframe size variabilityVSAvoidnumber of frame components to stock

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

A single universal base frame design is created that can accommodate multiple table or desk top sizes and configurations. By using standardized connection points and extendable profile members, the same base frame unit can be adapted to serve different applications, eliminating the need to maintain separate inventory for each frame size.

Inventive Principle:

Principle #6Universality (Multi-functionality)
