Solution Overview

Problem

Existing imaging devices have complex and unenjoyable mode selection processes, making it difficult for users to switch between various imaging modes.

Innovation Solution

A mode selection assembly that includes a selecting ring coupled to the lens barrel of an imaging device, which selects imaging modes by turning the ring to engage gear positions and trigger a mode selecting pulse through a contact switch and flexible flat cable, allowing easy switching between different imaging modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional mode selection methods are used, then multiple imaging modes are available, but the selection process becomes complicated and unenjoyable

Engineering Contradiction:

Improveimaging mode varietyVSAvoidmode selection process

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The mode selection ring is divided into multiple discrete gear positions, each corresponding to a specific imaging mode. This segmentation allows users to select modes through simple rotational steps rather than complex menu navigation, resolving the contradiction between mode variety and selection simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A mechanical intermediary system consisting of the mode selection ring, gear ring, and contact switch is introduced. The ring physically engages with gear positions and triggers electrical contacts to switch modes, providing an intuitive tactile interface that simplifies the selection process while supporting multiple modes

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If a mode selection ring with gear positions is implemented, then mode switching becomes simple and intuitive, but the device structure becomes more complex

Engineering Contradiction:

Improvemode switching simplicityVSAvoidselection assembly structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The mode selection ring is merged with the existing lens barrel structure, and the gear ring is integrated into the focusing mechanism. This combining of functions reduces the need for separate components and simplifies the overall device structure while maintaining ease of operation

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mode selection ring serves multiple functions: it acts as a focus ring for continuous focusing, a mode selection mechanism through gear position engagement, and a tactile user interface. This multi-functionality reduces the need for additional dedicated components, offsetting the added structural complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A mode selection assembly includes a gear ring coupled to a lens barrel of an imaging device having two or more gear positions, a selecting ring coupled to the lens barrel, and two or more photoelectric sensors. The gear ring is configured to be a sleeve of the lens barrel. The selecting ring is configured to adjust an imaging mode of the imaging device by turning the selecting ring. The selecting ring includes a first circular section having a plurality of recesses configured to engage with a first number of bulges of the gear ring. The two or more photoelectric sensors are attached to the first circular ring.
