Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If traditional portable structures use rigid frames and multiple connection components, then structural stability is improved, but assembly complexity and time consumption increase

Engineering Contradiction:
Improvestructural stabilityVSAvoidassembly complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The structure is divided into modular components (base, sides, resilient frame, spacing members) that can be independently manufactured and assembled. The resilient frame acts as a self-contained element that provides both structural support and automatic positioning, eliminating the need for multiple connection components while maintaining stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The resilient frame automatically assumes its functional shape upon deployment, providing self-positioning and self-support capabilities. The frame's elastic properties enable it to automatically maintain structural integrity and spacing without requiring additional fastening mechanisms or complex assembly procedures.

Inventive Principle:
Principle #25Self-service

2Strength

If portable structures use multiple connection components and assembly steps, then structural integrity is improved, but erection time increases

Engineering Contradiction:
Improvestructural integrityVSAvoiderection time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The resilient frame is pre-formed with its final functional geometry during manufacturing. When deployed, the frame automatically assumes its intended shape and position, eliminating the need for on-site assembly steps such as connecting multiple frame segments or adjusting alignment, thereby reducing erection time while maintaining structural integrity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Multiple functions are combined into single components: the resilient frame simultaneously provides structural support, defines the container shape, and maintains spacing between base and sides. The spacing members integrate the functions of positioning, support, and structural connection, reducing the total number of assembly steps required.

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If portable structures use rigid frames and multiple components, then load-bearing capacity is improved, but ease of storage and transport deteriorates

Engineering Contradiction:
Improveload-bearing capacityVSAvoidease of storage
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The resilient frame transitions between a compact stored state and an expanded functional state. During storage and transport, the frame can be collapsed or folded into a compact configuration. Upon deployment, the frame's elastic properties enable it to automatically expand to its full load-bearing configuration, providing both ease of storage and structural strength.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The physical parameters of the frame (length, volume, configuration) are dynamically changed between stored and operational states. The resilient material allows the frame to be compressed into a compact form for storage, then automatically return to its expanded load-bearing configuration when deployed, resolving the contradiction between storage ease and load-bearing capacity.

Inventive Principle:
Principle #35Parameter changes

4Stability of the object's composition

If portable structures require assembly of multiple components, then structural stability is improved, but ease of assembly deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of assembly
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

Complex connection mechanisms and multiple assembly steps are extracted from the design. The resilient frame is provided as a single pre-formed component that automatically provides structural stability through its elastic properties, eliminating the need for complex connection hardware and multi-step assembly procedures while maintaining structural integrity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The resilient frame provides self-positioning and self-support capabilities, automatically assuming its functional configuration upon deployment. This self-service characteristic eliminates the need for user intervention in complex assembly operations, making the structure easy to assemble while maintaining high structural stability.

Inventive Principle:
Principle #25Self-service
