Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display screen is made expandable to accommodate varying display needs, then the adaptability is improved, but the device complexity increases due to sliding frames and adjustment mechanisms
Solution Approach 1:
The display holder is divided into first and second foldable portions located on distal ends, allowing independent folding and expansion of each section. This segmentation enables the display to achieve multiple size configurations without requiring a completely complex redesign of the entire structure.
Solution Approach 2:
The sliding frame component with first and second sliding frames are nested within the display holder structure. The adjustment components are integrated within the sliding frames, creating a compact nested arrangement that reduces overall complexity while maintaining expandability functionality.
2Ease of operation
If the display screen is made flexible and adjustable, then the ease of operation is improved, but the reliability may deteriorate due to additional moving parts and mechanical components
Solution Approach 1:
The display holder incorporates foldable portions that can dynamically transition between folded and unfolded states. The sliding frames can move along guide channels to dynamically adjust the display size. These dynamic features enable easy operation while the guide channels and gear mechanisms provide controlled movement to maintain reliability.
Solution Approach 2:
A hall effect sensor detects the position of the sliding frame and provides feedback to the control circuit. This feedback mechanism ensures that the display reaches the desired extended or retracted position accurately, preventing over-extension or improper positioning that could compromise reliability.
3Area of moving object
If the display screen is extended to provide larger display area, then the area of moving object is improved, but the volume of stationary object increases to accommodate the extended display
Solution Approach 1:
The display holder utilizes vertical folding portions instead of only horizontal extension. By folding the display holder vertically and using sliding frames that move along guide channels, the display can achieve a larger display area without proportionally increasing the device volume, as the expansion occurs in multiple dimensions rather than a single direction.
