Retaining Claw Structure to Prevent Screen Contact During Display Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic device retaining devices often cause contact between the screen of a display and the retaining claws, potentially damaging the screen when the display is rotated.
Innovation Solution
An electronic device retaining structure featuring a base with a placing surface and retainers mounted on its periphery, where each retainer has a retaining claw with an upward slope to contact the display's side edge and a downward slope to press the device body against the surface, preventing screen contact and ensuring secure retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional retaining claws are used to retain the electronic device, then the device can be securely retained, but the screen of the display may come into contact with the retaining claws during rotation
Solution Approach 1:
The retaining claw is segmented into two distinct functional regions: an upward slope portion and a downward slope portion. The upward slope portion contacts the side edge of the display to prevent screen contact, while the downward slope portion presses the device body against the placing surface to ensure retention. This segmentation allows each portion to perform its specific function without interfering with the other.
Solution Approach 2:
Different portions of the retaining claw are designed with different geometric properties tailored to their specific functions. The upward slope portion has a gentle incline suitable for contacting the display side edge, while the downward slope portion has a steeper incline for pressing the device body. This local differentiation of geometric quality optimizes the performance of each region.
2Device complexity
If the retaining claw has a simple structure, then the device complexity is reduced, but it cannot prevent screen contact during display rotation
Solution Approach 1:
The retaining claw is divided into two slope portions that can be formed as a single integrated structure. This segmentation approach allows the complex function of preventing screen contact while maintaining retention to be achieved through geometric design rather than multiple separate components, thus controlling overall device complexity.
Solution Approach 2:
The geometry of the retaining claw is modified by introducing two slope portions with different angles and orientations. This parameter change in the claw's shape transforms it from a simple retaining element to a multi-functional component that prevents screen contact while maintaining device retention, without adding mechanical complexity.

AI summary
An electronic device retaining structure includes: an electronic device having a device body and a display rotatably connected to the device body; a base having a placing surface placed with the electronic device; and at least one pair of retainers mounted on an outer periphery of the base and facing each other. Each of the at least one pair of retainers has a retaining claw protruding from an outer side to an inner side of the placing surface. The retaining claw has, at the upper part, an upward slope sloping upward from the inner side toward the outer side and coming into contact with a side edge of the display when the display is rotated in a direction approaching the placing surface, and below the upward slope, a downward slope sloping downward from the inner side toward the outer side and pressing the device body against the placing surface.
