Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional riveting techniques are used to attach the coupling element to the web, then the coupling element can be securely attached, but the construction process becomes more complex and time-consuming

Engineering Contradiction:
Improveattachment securityVSAvoidconstruction process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the riveting operation from the assembly process by providing pre-drilled holes and removal slots in the coupling element. This allows the rivets to be inserted and then easily removed through the slots, eliminating the need for complex riveting operations while maintaining secure attachment during assembly.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The coupling element is prepared in advance with pre-drilled holes and removal slots formed during manufacturing. This preliminary action eliminates the need for on-site drilling and complex riveting operations, simplifying the construction process while ensuring proper attachment security.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If the coupling element is designed with high rigidity for structural stability, then the grid structure becomes more stable, but the disengagement process becomes more difficult

Engineering Contradiction:
Improvegrid structure stabilityVSAvoiddisengagement ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The coupling element incorporates removal slots that enable dynamic transition between engaged and disengaged states. The slots allow rivets to be easily withdrawn, providing a simple disengagement mechanism that does not compromise the rigidity and stability of the coupled structure during its service life.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The coupling element is segmented with removal slots that divide the structure into engageable and disengageable portions. This segmentation allows the main body to maintain rigidity for structural stability while the slot-containing portions enable easy disengagement by allowing rivet removal.

Inventive Principle:
Principle #1Segmentation

3Strength

If the coupling element uses complex formation operations, then the structural integrity is improved, but the manufacturing process becomes more difficult

Engineering Contradiction:
Improvestructural integrityVSAvoidmanufacturing ease
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The coupling element is manufactured with pre-formed holes and removal slots during the initial forming process. This preliminary action ensures proper structural integrity is achieved through controlled forming operations, while eliminating the need for complex secondary operations in the field, thereby improving ease of manufacture and installation.

Inventive Principle:
Principle #10Preliminary action
