Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a slide body with elastic support structure and gear assembly is used to enable camera module rotation, then the camera module can rotate to photograph subjects in opposite directions, but frequent slide-in/slide-out operations cause deformation of elastic support structure, wear and tear on gear assembly, and interference with surrounding structures

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent replaces the mechanical elastic support structure and gear assembly with a magnetic field-based system. Magnetic force generating members (electromagnets) and magnetic force reactive members (magnetic sensors or magnetic beads) are used to detect slide body position and control camera module rotation, eliminating mechanical contact and wear during frequent operations

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces magnetic fields as an intermediary between the slide body and camera module. The magnetic force generating members create magnetic fields that interact with magnetic force reactive members to transmit position information and control rotation without direct mechanical contact, preventing interference with surrounding structures

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If a mechanical gear assembly and elastic support structure are used for camera module rotation, then the camera module can be positioned correctly, but tilting occurs causing the camera surface to mismatch the slide body outer surface after frequent operations

Engineering Contradiction:

Solution Approach 1:

The patent replaces mechanical positioning mechanisms with magnetic field-based positioning. Magnetic force generating members and reactive members work together to precisely control camera module orientation and prevent tilting, maintaining alignment stability without mechanical wear or deformation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements feedback control using magnetic force reactive members that detect the position of the slide body and provide feedback signals to control the camera module rotation. This closed-loop control ensures the camera surface remains aligned with the slide body outer surface even after frequent operations
