Solution Overview

Problem

Current projection devices lack flexibility in their protective mesh structures, as they are permanently fixed, making it difficult for users to selectively install or remove the mesh according to their needs, especially when the device is tilted or flipped, leading to potential foreign object entry through air inlets or outlets.

Innovation Solution

A projection device design featuring a casing structure with position-limiting and stopper structures allows for the selective installation and removal of a protective mesh, ensuring the mesh is securely attached and can be easily disassembled as needed, enhancing user flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the protective mesh is permanently fixed inside the projection device, then the protective function is ensured, but the flexibility and ease of maintenance are reduced

Engineering Contradiction:
Improveprotective functionVSAvoidease of maintenance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The protective mesh is designed as a separate, detachable component from the projection device housing. The mesh can be removed through a designated opening without disassembling the entire device, allowing users to easily clean or replace the mesh while maintaining the protective function when installed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protective mesh transitions from a static, permanent fixture to a dynamic, removable component. The mesh can be inserted and removed based on user needs, providing flexibility in maintenance while ensuring protection when in place.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If the protective mesh is permanently fixed, then the structural integrity is maintained, but the adaptability to different usage scenarios is reduced

Engineering Contradiction:
Improvestructural integrityVSAvoidadaptability to usage scenarios
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The protective mesh is segmented as an independent component that can be selectively installed or removed. This allows the device to adapt to different usage scenarios - the mesh can be installed when protection is needed and removed when accessibility is prioritized, without affecting the overall structural integrity of the projection device.

Inventive Principle:
Principle #1Segmentation

3Strength

If the protective mesh is permanently fixed by hot melting or screw locking, then the mesh is securely attached, but the ease of disassembly and reinstallation is reduced

Engineering Contradiction:
Improveattachment strengthVSAvoidease of disassembly and reinstallation
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The protective mesh is designed as a separate component with a dedicated installation mechanism. The mesh can be securely attached through a simple insertion process into a corresponding housing structure, eliminating the need for complex fastening methods like hot melting or screw locking while maintaining strong attachment and ease of disassembly.

Inventive Principle:
Principle #1Segmentation

AI summary

A projection device includes a casing structure and a protective mesh structure. The casing structure includes a casing, at least one position-limiting structure, and at least one stopper structure. At least one position-limiting groove is formed between a side cover of the casing and the position-limiting structure. The stopper structure is connected to the side cover and protrudes toward a containing space inside the casing. The protective mesh structure includes a protective mesh body and at least one protective mesh position-limiting portion. The protective mesh body is adapted to be installed in the containing space and at least partially limited in the position-limiting groove. The protective mesh position-limiting portion is connected to the protective mesh body and leans against the stopper structure of the casing structure, so as to prevent the protective mesh structure from being separated from the casing structure.
