Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the optical assembly is made adjustable to align with different user sight lines, then the adaptability and user experience are improved, but the device complexity increases due to additional adjustment mechanisms

Engineering Contradiction:
Improveadaptability to different user sight linesVSAvoidcomplexity of adjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The optical assembly is designed with rotational adjustability, allowing it to dynamically change its position and orientation to adapt to different user sight lines. The rotation mechanism enables the optical assembly to move from a fixed position to multiple adjustable positions, improving adaptability while maintaining a relatively simple structural design through controlled dynamic movement.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a rotational adjustment mechanism is added to the optical assembly, then the ease of operation is improved, but the device complexity increases due to additional components like rotating shafts and damping mechanisms

Engineering Contradiction:
Improveconvenience of optical assembly adjustmentVSAvoidnumber of adjustment components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

A damping mechanism is introduced as an intermediary element between the rotation mechanism and the optical assembly. This damping component (using rubber rings or damping elements) mediates the rotational movement, providing smooth control and stable positioning without requiring complex control systems. The intermediary damping mechanism simplifies the overall control structure while improving ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The damping mechanism automatically provides friction-based control during rotation, enabling the optical assembly to self-position and self-lock at desired angles without requiring additional actuators or control systems. The rubber rings or damping elements generate natural friction that assists the rotation mechanism, allowing the system to serve itself in achieving stable positioning.

Inventive Principle:
Principle #25Self-service
