Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If screw connection is used to fix two objects, then coupling stability is improved, but ease of separation deteriorates

Engineering Contradiction:

Improvecoupling stabilityVSAvoidease of separation

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The connection structure is divided into separate components: a connection portion with a pressing element and a corresponding receiving structure. This segmentation allows the connection to be made by simply pressing the elements together, enabling easy assembly and disassembly while maintaining stable coupling during operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The traditional screw-threaded mechanical system is replaced with a pressing-based connection mechanism. The connection portion utilizes elastic deformation and friction forces instead of threading, allowing for tool-free assembly and disassembly while maintaining connection stability during use.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Stability of the object's composition

If screw connection is used to fix two objects, then coupling stability is improved, but assembly complexity deteriorates

Engineering Contradiction:

Improvecoupling stabilityVSAvoidassembly complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The complex threading mechanism is extracted and replaced with simple pressing elements. The connection portion consists of a pressing element and a receiving structure that can be assembled by direct pressing, eliminating the need for screws, threads, and associated tools, thereby simplifying the assembly process while maintaining connection stability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The connection structure is designed to be self-assembling through simple pressing actions. The pressing element automatically engages with the receiving structure when pressed together, and the elastic deformation provides self-centering and alignment, eliminating the need for complex alignment procedures or additional fastening steps.

Inventive Principle:

Principle #25Self-service

3Stability of the object's composition

If screw connection is used to fix two objects, then coupling stability is improved, but time consumption for assembly and disassembly deteriorates

Engineering Contradiction:

Improvecoupling stabilityVSAvoidtime consumption for assembly and disassembly

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The pressing element is pre-formed with the appropriate elastic properties and geometry during manufacturing. This preliminary preparation allows the connection to be made by a single pressing action without requiring assembly operations such as threading, tightening, or alignment adjustments, significantly reducing assembly time while maintaining connection stability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The connection process skips the time-consuming steps of threading, tightening, and alignment that are required for screw connections. By using a pressing-based mechanism with pre-formed elastic elements, the connection is established rapidly in a single motion, and disassembly is equally swift by simply releasing the pressing force.

Inventive Principle:

Principle #21Skipping (Rushing through)
