Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotatable display devices lack a flexible control mechanism to accommodate displays of varying sizes and mechanical characteristics, necessitating a unified torque and rotation speed setting that fails to account for individual display properties.
Innovation Solution
A rotating device with a processor that receives identification information from mounted displays, calculates torque values based on size, weight, and center of gravity, and adjusts rotation speed and torque accordingly, using stored driving information to control a step motor for precise rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unified torque and rotation speed setting is used for all displays, then the control mechanism is simple, but it fails to account for individual display properties such as size, weight, and center of gravity
Solution Approach 1:
The patent implements dynamic control by storing multiple torque values and rotation speeds in memory corresponding to different display properties, and selectively applying the appropriate parameters based on the specific display device being used. This allows the system to adapt its control parameters dynamically rather than using fixed unified settings.
Solution Approach 2:
The patent changes operational parameters (torque values and rotation speeds) based on display characteristics such as size, weight, and center of gravity location. By storing multiple sets of parameters and selecting the appropriate set based on the specific display device, the system optimizes rotation performance for each individual display configuration.
2Adaptability or versatility
If different torque and rotation speed settings are configured for each display, then adaptability to individual display properties is improved, but the control mechanism becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-storing multiple torque values and rotation speeds in memory corresponding to different display properties before operation. This allows the system to quickly retrieve and apply appropriate parameters without complex real-time calculations, simplifying the control mechanism while maintaining adaptability.
Solution Approach 2:
The patent manages complexity by organizing multiple parameter sets (torque values and rotation speeds) in memory, each corresponding to specific display characteristics. The processor selectively retrieves and applies the appropriate parameter set based on the detected display properties, enabling adaptability without requiring complex control logic for each individual parameter adjustment.
3Force
If torque value is increased for heavier displays, then rotation capability is improved, but rotation speed must be reduced to maintain control
Solution Approach 1:
The patent simultaneously adjusts both torque values and rotation speeds based on display properties such as weight and center of gravity. By storing coordinated parameter sets in memory, the system increases torque for heavier displays while correspondingly reducing rotation speed to maintain proper control, ensuring optimal rotation performance for each display configuration.
Solution Approach 2:
The patent implements dynamic parameter adjustment where torque and rotation speed are not independently set but are coordinated based on display characteristics. The system dynamically selects appropriate parameter combinations from stored sets, ensuring that increased torque for heavier displays is paired with reduced rotation speed to maintain control stability.
