Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple switches are mounted on the electronic device to provide various functions, then the device functionality is improved, but the space occupation increases and space utilization efficiency decreases
Solution Approach 1:
The patent implements a nested turntable structure where a second turntable is rotatably disposed on the first turntable, which itself is rotatably disposed on the housing. This nested arrangement allows multiple switch functions to be integrated in a compact space, with the second turntable providing additional control options without significantly increasing the overall device footprint.
Solution Approach 2:
The patent transitions from a two-dimensional layout of switches on the device surface to a three-dimensional stacked turntable assembly. By utilizing the vertical dimension and creating overlapping rotational layers, the design integrates multiple switch functions into a compact spatial configuration, reducing the horizontal space occupation while maintaining functionality.
2Adaptability or versatility
If switches are disposed at different positions on the electronic device, then various functions are provided, but the operation convenience decreases and users need to spend more time to find and operate each switch
Solution Approach 1:
The patent merges multiple switch functions into a unified stacked turntable assembly located at a single position on the device. The first and second turntables are integrated together, allowing users to access various functions through a集中的 control interface rather than searching across different locations, thereby improving operation convenience while maintaining function variety.
Solution Approach 2:
The turntable assembly serves as a universal control interface that integrates multiple switch functions. Both the first turntable (with engaging structures for multi-step control) and the second turntable (with annular engaging structures for stepless control) can cooperate with switch elements to realize different functions, providing a multi-functional control system at a centralized location.
3Area of stationary object
If a stacked turntable assembly is implemented to improve space utilization, then the space efficiency is improved, but the device complexity increases due to engaging structures and fixing members
Solution Approach 1:
The patent segments the control system into distinct functional modules: the first turntable with its engaging structures for multi-step control, the second turntable with annular engaging structures for stepless control, and various fixing members. This segmentation allows each component to perform its specific function while being integrated into a compact stacked assembly, achieving space efficiency through modular design.
4Adaptability or versatility
If engaging structures are added to form multi-step and stepless turntable assemblies, then the switch function integration is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent employs standardized engaging structures that can be replicated across the first and second turntables. The engaging structures on the first turntable and the annular engaging structures on the second turntable follow consistent design patterns, allowing for standardized manufacturing processes and reducing the overall manufacturing complexity despite the multiple functions integrated.
