Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the flexible display panel is pulled out and extended to a required length, then the display area is increased and energy consumption is reduced through regional display, but the device structure becomes more complex requiring limiting components and rotation shafts
Solution Approach 1:
The patent merges the limiting component and rotation shaft into an integrated assembly where the rotation shaft serves as both the curling mechanism and the mounting structure for the limiting component. This combination reduces the number of separate parts while achieving both the extendable display function and the structural support needed for energy-efficient regional display.
Solution Approach 2:
The rotation shaft is designed to perform multiple functions: it enables the flexible display panel to curl and extend, provides a mounting structure for the limiting component, and acts as a mechanical element for controlling the display area. This multi-functionality reduces overall device complexity while enabling energy-saving regional display operations.
2Area of stationary object
If the limiting component is designed with multiple functions, then space is saved and cost is controlled, but the component design becomes more complex
Solution Approach 1:
The limiting component is designed to perform multiple functions including limiting the extension distance of the flexible display panel, providing a latching mechanism through the limiting pin and gear, and serving as a structural support element. This multi-functionality consolidates several components into one, saving space and controlling cost while managing complexity through functional integration.
Solution Approach 2:
The limiting component integrates the limiting pin, gear, and latching mechanism into a single assembled unit that works in conjunction with the rotation shaft. This merging of functions into one component reduces the overall number of parts, saves assembly space, and simplifies the bill of materials while achieving the required space and cost control objectives.
3Volume of moving object
If the flexible display panel is curled inside the display device main body, then space is saved for portable storage, but the mechanism for curling and resetting requires additional components
Solution Approach 1:
The curling mechanism merges the rotation shaft and reset component into an integrated assembly where the rotation shaft provides the rotational motion for curling while the reset component (limiting pin and gear) provides both the resetting function and structural support. This combination reduces the number of separate components needed for the curling and storage function.
Solution Approach 2:
The rotation shaft serves multiple purposes: it enables the curling action for compact storage, provides a mounting structure for the reset component, and acts as a mechanical element for controlling the display panel extension. This multi-functionality reduces overall device complexity while achieving space-efficient portable storage.
