Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a power cord is connected to the camera body, then the camera can be continuously powered, but the power cord exerts pulling force on the camera causing displacement and affecting shooting stability
Solution Approach 1:
The power cord connection is extracted from the camera body and relocated to a separate charging base. The camera contains only a battery module and wireless charging receiving coil, while the power cord connects to the base, eliminating the pulling force on the camera during operation.
Solution Approach 2:
The mechanical connection of the power cord to the camera body is replaced with a wireless charging system using electromagnetic induction. The camera and base communicate and transfer power wirelessly, eliminating the mechanical pulling force while maintaining power supply functionality.
2Reliability
If waterproofing measures such as dispensing glue or adding external covers are applied to the power cord connection, then water penetration is reduced, but the complexity of the structure increases and water may still enter the camera interior
Solution Approach 1:
The power cord connection interface is extracted from the camera body entirely, eliminating the need for waterproofing measures at the camera. The wireless charging receiving coil is sealed within the camera housing, and the power cord connects only to the external base, removing the vulnerability point.
3Use of energy by moving object
If a power cord or power interface is provided on the camera body, then power can be supplied to the camera, but it impacts the camera layout and appearance integrity
Solution Approach 1:
The power cord connection is extracted from the camera body and relocated to a separate charging base. The camera maintains a clean, integrated appearance with no external power interfaces, while still achieving continuous power supply through wireless charging when placed on the base.
4Reliability
If the camera is fixed in a specific position for wireless charging, then stable power transfer is achieved, but the camera cannot be adjusted to different shooting angles
Solution Approach 1:
The system transitions from a static fixed-position charging approach to a dynamic adjustment mechanism. The camera can be rotated and adjusted to different angles while remaining magnetically attracted to the base, allowing both stable charging and flexible positioning.
Solution Approach 2:
The wireless charging system is segmented into multiple independent magnetic attraction zones around the base. This allows the camera to be attracted to different segments or zones, enabling angle adjustment while maintaining charging functionality.
