Rotary Knob Assembly for Display Device Image Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices controlled by remote controls have high costs and low flexibility in switching images, limiting user interaction and operational ease.
Innovation Solution
A display device incorporating a rotary knob assembly with a rotary knob cap and rotary rod connected to a control circuit board, allowing users to switch images through rotation and lock them through pressing, with an integrated switch encoder and elastic connecting member for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote control is used to control the display device, then the user can switch images displayed, but the cost increases and flexibility decreases
Solution Approach 1:
The patent extracts the control function from the remote control system and integrates it directly into the display device by adding a rotary knob assembly. This eliminates the need for external remote control equipment, reducing overall system cost while improving operational flexibility and responsiveness.
Solution Approach 2:
The control function is merged with the display device by integrating the rotary knob assembly directly onto the device housing. This combination consolidates the control system, reducing the need for separate remote control components and lowering overall system complexity and cost.
2Adaptability or versatility
If a rotary knob assembly is integrated into the display device, then user interaction flexibility improves, but the device structure becomes more complex
Solution Approach 1:
The rotary knob assembly is designed to perform multiple functions: rotation for image switching and pressing for image locking. This multi-functionality increases user interaction versatility while minimizing the number of separate components needed, thereby controlling structural complexity.
Solution Approach 2:
The rotary knob assembly is nested within the display device housing structure, with the rotary knob cap positioned on the outer surface and internal components (rotary rod, switch encoder) integrated within the device casing. This nesting approach minimizes external structural additions while maintaining functional versatility.
3Shape
If the rotary knob cap is disposed outside the casing, then aesthetic design is improved, but the internal space for components is reduced
Solution Approach 1:
The rotary knob cap is positioned on the outer surface of the housing, utilizing the external dimensional space rather than internal volume. This allows the aesthetic interface element to extend outward, improving visual appeal and ergonomics without encroaching on the internal space required for electronic components.
