Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate hole is formed in the plate for fastening the stand, then the stand can be securely attached to the plate, but the manufacturing process becomes more complex and costly

Engineering Contradiction:
Improvesecure attachment of stand to plateVSAvoidmanufacturing process complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent combines the stand base with the fixing member into a single integrated component. The stand base includes an integrated fixing member with a pressing portion that directly contacts the plate, eliminating the need for separate holes. This merging of functions allows secure attachment while simplifying manufacturing, as the integrated structure can be produced as one piece without additional drilling or fastening operations.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If fastening means are exposed on the plate surface, then the attachment structure is simple and visible, but the aesthetic appeal is reduced

Engineering Contradiction:
Improvesimplicity of attachment structureVSAvoidaesthetic appearance of plate surface
Core Design Contradiction:
Device complexityVSShape

Solution Approach 1:

The patent extracts the fastening function from the visible plate surface by positioning the fixing member on the rear surface of the plate. The pressing portion contacts the plate from behind, allowing the attachment structure to remain simple and functional while the plate front surface remains clean and aesthetically pleasing without exposed fasteners or holes.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If the assembly process requires precise alignment and multiple steps, then the fixing is more secure, but the assembly time increases

Engineering Contradiction:
Improvesecurity of fixingVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent incorporates a positioning protrusion on the stand base that aligns with a corresponding positioning groove on the plate before pressing. This preliminary positioning action ensures correct alignment is achieved automatically during assembly, eliminating the need for complex alignment procedures. The pressing portion then applies force to securely fix the stand, achieving both security and speed in a single streamlined operation.

Inventive Principle:
Principle #10Preliminary action

4Stability of the object's composition

If the bracket structure is rigid and fixed, then the assembly is stable, but the adaptability to different environments is reduced

Engineering Contradiction:
Improvestability of bracket assemblyVSAvoidadaptability to environmental conditions
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent incorporates a buffer member between the bracket and the plate that can elastically deform or compress. This dynamic element allows the rigid bracket structure to adapt to variations in plate thickness, surface irregularities, or environmental conditions such as temperature changes. The buffer member maintains stable contact and fixing force while accommodating dimensional variations, thus providing both stability and adaptability.

Inventive Principle:
Principle #15Dynamics
