Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a traditional projection screen is used, then the structure is simple, but the assembly is difficult and time-consuming

Engineering Contradiction:

Improvestructure simplicityVSAvoidassembly time

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The projection screen is divided into modular frame segments that can be easily assembled together. The frame consists of multiple adjustable segments that connect through standardized joints, allowing quick assembly without complex tools or procedures.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The frame incorporates adjustable and removable components that allow dynamic reconfiguration. Legs can be attached or removed, and frame segments can be adjusted to accommodate different mounting scenarios, making assembly adaptable and efficient.

Inventive Principle:

Principle #15Dynamics

2Stability of the object's composition

If a fixed mounting system is used, then the installation is stable, but the adaptability to different mounting scenarios is limited

Engineering Contradiction:

Improveinstallation stabilityVSAvoidmounting flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The frame is designed with universal mounting capabilities, incorporating both wall-mounting interfaces and floor-stand leg attachments. The same basic frame structure can be configured for different mounting scenarios by simply adding or removing legs, providing versatility without compromising structural integrity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mounting system transitions from static to dynamic by allowing the user to convert between wall-mounted and floor-standing configurations. Adjustable joints and removable legs enable the frame to adapt its configuration while maintaining stability in each mode.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the screen is not tensioned, then the assembly is easier, but the image display has distortion

Engineering Contradiction:

Improveassembly easeVSAvoidimage display quality

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The frame design allows the screen material to be tensioned through the assembly process itself. As frame segments are connected and tightened, the screen material automatically becomes tensioned, eliminating the need for separate tensioning operations while ensuring proper image display quality.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The screen material is pre-attached to the frame segments in a relaxed state during manufacturing, allowing easy assembly. During installation, the sequential tightening of frame joints automatically tensions the screen to the correct level, achieving proper tension without complex pre-tensioning procedures.

Inventive Principle:

Principle #10Preliminary action
