Innovation Solution
Incorporating magnetic elements on the projector housing that attract a magnetic attraction kit on the protective sleeve, allowing for easy assembly and disassembly through magnetic attraction and engagement of fixing structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional protective sleeves are used for projection devices, then the projection device is protected from damage, but the protective sleeve is difficult to assemble and disassemble
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, clips, adhesives) with a magnetic field-based attachment system. Magnetic elements are embedded in both the protective sleeve and the projection device housing, creating an invisible force field that automatically attracts and secures the sleeve when brought near the device. This substitution of mechanical fasteners with magnetic attraction resolves the contradiction by providing both strong protective attachment and effortless assembly/disassembly through simple proximity-based interaction.
Solution Approach 2:
The patent utilizes magnetic field strength as a controllable parameter to achieve optimal attachment. By carefully selecting magnet sizes, materials, and arrangements, the magnetic attraction force can be tuned to provide sufficient holding strength for protection while allowing easy separation when magnetic force is overcome by deliberate user action. This parameter optimization enables the same magnetic system to satisfy both strong attachment and easy release requirements.
2Ease of operation
If magnetic elements are added to the projector housing, then the protective sleeve becomes easy to assemble and disassemble, but the device complexity increases
Solution Approach 1:
The magnetic elements are nested within the existing structures of both the protective sleeve and the projection device housing. Rather than adding external protruding components, the magnets are embedded or integrated into the walls and surfaces of these components. This nesting approach minimizes the increase in device complexity by utilizing existing structural space and avoiding additional external parts, while still achieving the desired easy assembly and disassembly functionality.
3Productivity
If magnetic attraction module is used, then the protective sleeve can be quickly attached and detached, but the manufacturing complexity increases
Solution Approach 1:
The patent merges the magnetic elements with the manufacturing processes of the protective sleeve and housing components. During plastic injection molding or metal forming, magnetic particles or pre-formed magnets are integrated directly into the component structure in a single manufacturing step. This combining of magnetic attachment functionality with existing manufacturing processes avoids the need for separate magnetic component assembly steps, thereby maintaining manufacturing simplicity while achieving quick attachment and detachment capabilities.
