Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery is mounted at the bottom of the red dot sight main body, then the power supply is integrated and stable, but the battery replacement requires disassembly and recalibration which is inconvenient and time-consuming
Solution Approach 1:
The charging cover is designed as a detachable module that separates the charging function from the main sight body. This segmentation allows the charging cover to be removed and replaced independently without disassembling the main sight, thereby avoiding recalibration while enabling convenient battery replacement.
Solution Approach 2:
The charging cover acts as an intermediary component between the user and the battery. Instead of directly accessing and replacing the battery in the main body, users interact with the charging cover which houses the battery and charging circuitry. This intermediary design simplifies the replacement process and eliminates the need for recalibration.
2Ease of operation
If the housing detachably covers the rechargeable red dot sight, then the charging cover can be easily attached and removed, but the connection between charging cover conductive assembly and the sight must be maintained
Solution Approach 1:
The conductive assembly incorporates elastic conductive members that can dynamically adjust their position and pressure. When the charging cover is attached, these elastic members automatically make contact with the sight's contact terminals and maintain stable electrical connection through their elastic force, accommodating any minor positioning variations.
Solution Approach 2:
The magnetic attraction mechanism automatically aligns and secures the charging cover to the sight body when brought near. This self-aligning feature ensures that the conductive assemblies are properly positioned and connected without requiring precise manual alignment by the user, thereby maintaining reliable electrical connection while simplifying the attachment operation.
3Extent of automation
If the magnet is used to attract the rechargeable red dot sight, then the charging cover connection is secure and automatic, but the magnetic force must be strong enough to hold the assembly
Solution Approach 1:
The magnetic member is strategically positioned and sized to concentrate the magnetic attraction force at the critical connection interface between the charging cover and sight body. This localized magnetic field ensures strong holding force precisely where needed for secure connection, while the overall structure remains lightweight and compact.
