Solution Overview

Problem

Existing camera systems with lens units having a stop ring for adjusting aperture values have a fixed sort order for auto indications and aperture values, limiting user flexibility in customizing the order.

Innovation Solution

A camera system with a lens unit and camera body that allows users to change the sort order of auto indications and aperture values through a stop ring, utilizing a display section and camera control section to execute change modes, including reversal, position adjustment, and selection of aperture values, with a position detection section and stop unit for precise control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed sort order of auto indication and aperture values is used in the stop ring, then the device structure is simple and reliable, but the user cannot change the sort order, reducing adaptability and ease of operation

Engineering Contradiction:
Improveuser ability to change sort orderVSAvoidsystem complexity for enabling sort order change
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a dynamic sort order system where the arrangement of aperture values and auto indication on the stop ring can be changed by the user. The camera control section stores multiple sort order patterns and switches between them based on user selection, transforming a static fixed arrangement into a dynamic reconfigurable one that adapts to different user preferences and shooting scenarios

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of sort order arrangement by providing multiple predefined patterns (e.g., ascending order, descending order, custom sequences) and allowing users to select among them. This parameter change approach enables flexibility without requiring complete redesign of the stop ring structure, as the same physical components can display different sequences based on the selected pattern

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If multiple change modes are provided for sort order adjustment, then user flexibility and ease of operation are improved, but the control system complexity increases

Engineering Contradiction:
Improveease of sort order adjustmentVSAvoidcamera control section complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-defining multiple sort order patterns (such as ascending order, descending order, and other common sequences) and storing them in the camera control section before use. When the user wants to change the sort order, they simply select from these pre-configured patterns rather than configuring each arrangement from scratch, which simplifies the operation while maintaining the camera control section's ability to handle multiple patterns

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of requiring users to manually configure each sort order by dragging and dropping individual aperture values, the patent inverts the approach by providing ready-made patterns that users can select with a single action. This inversion transforms a complex multi-step configuration process into a simple selection process, improving ease of operation while reducing the effective complexity users experience

Inventive Principle:
Principle #13The other way round (Inversion)
