Solution Overview

Problem

Existing desk tops, particularly in bed desks and mobile desks, occupy large packaging spaces due to their integrated mounting structures, leading to increased transportation costs, especially during cross-border shipping.

Innovation Solution

A combined desk top design featuring a U-shaped left and right support frame structure that allows for disassembly, stacking, and easy assembly, reducing packaging space and transportation costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If an integrated mounting structure is adopted for the desk top, then the desk can be assembled easily, but the packaging space occupied is large, increasing transportation costs

Engineering Contradiction:
Improveassembly convenienceVSAvoidpackaging space
Core Design Contradiction:
Ease of manufactureVSVolume of stationary object

Solution Approach 1:

The desk top is divided into multiple detachable components: a desk top panel, support legs, and connecting components with threaded holes. This segmentation allows each part to be packaged separately, reducing the overall packaging volume and transportation costs while maintaining ease of assembly through the threaded connection structure

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If the desk top is designed with a large overall layout, then the functional area is increased, but a larger packaging box is needed, increasing transportation costs

Engineering Contradiction:
Improvedesk top functional areaVSAvoidpackaging box size
Core Design Contradiction:
Area of stationary objectVSVolume of stationary object

Solution Approach 1:

The desk top is segmented into a panel and detachable support legs. The support legs can be folded or detached, allowing the large functional area to be collapsed into a compact form for packaging, thus reducing packaging box size while maintaining the original functional area when assembled

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support legs are designed to nest within or alongside the desk top panel when disassembled, creating a compact packaged form. The connecting components with threaded holes enable the nested structure to be securely reassembled, maximizing the functional area while minimizing packaging volume

Inventive Principle:
Principle #7Nested doll (Nesting)
