Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device support stands fail to securely rotate electronic devices within confined spaces while allowing easy orientation changes without additional force or space, and often allow movement during operations.
Innovation Solution
A support stand with a pivot mechanism that enables electronic devices to rotate around a horizontal axis with minimal load, featuring a gear engagement system for secure angular positioning and an elastic member for continuous contact, along with a lock plate for theft prevention and adjustable design for various device sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional support stand is used to hold the electronic device, then the device can be supported in an upright position, but the device cannot be rotated easily or securely fixed at different orientations
Solution Approach 1:
The support stand employs a dynamic locking mechanism that transitions between locked and unlocked states. The operating lever controls a lock plate that can engage with or disengage from engagement protrusions on the holding unit, enabling the device to be securely fixed at desired orientations or freely rotated as needed.
Solution Approach 2:
The pivot mechanism incorporates a self-latching feature where the lock plate automatically engages with the engagement protrusions when the operating lever is released. This self-service mechanism maintains secure fixation without requiring continuous user intervention, while still allowing easy rotation when the lever is activated.
2Ease of operation
If the electronic device is allowed to rotate freely on the support stand, then orientation changes are easy, but the device cannot be securely fixed at specific positions
Solution Approach 1:
The support stand provides dynamic control over device orientation through the pivot mechanism. The device can rotate freely when the lock plate is disengaged, and be securely fixed at specific orientations when the lock plate engages with the engagement protrusions, allowing users to switch between rotational freedom and positional stability as needed.
Solution Approach 2:
The pivot mechanism changes the rotational parameter of the device by allowing rotation through a range of angles (e.g., 0 to 360 degrees) and then locking at specific angular positions where the engagement protrusions align with the lock plate, effectively controlling both the freedom of rotation and the fixed positions.
3Adaptability or versatility
If a torque converter is used to enable angle adjustment, then the device can be held at desired angles, but the mechanism becomes complex and requires more space
Solution Approach 1:
The rotation mechanism is segmented into distinct functional components: the holding unit with engagement protrusions, the lock plate with corresponding engagement surfaces, and the operating lever. This segmentation allows each component to perform its specific function simply, avoiding the need for a complex integrated torque converter while achieving the same angle adjustment capability.
Solution Approach 2:
The lock plate serves as an intermediary element between the holding unit and the operating lever. It mediates the locking action by engaging with the engagement protrusions when the lever is actuated, providing a simple mechanical solution for angle fixation without requiring a complex torque converter mechanism.
4Force
If the support stand is designed to rotate the device with minimal force, then orientation changes are quick and easy, but the device may not be securely held during operation
Solution Approach 1:
The pivot mechanism provides dynamic control over the force required to rotate the device. When the lock plate is disengaged, minimal force is needed to rotate the device to any orientation. When the lock plate engages with the engagement protrusions, the same mechanism provides strong holding force to securely fix the device at the desired position, eliminating the trade-off between ease of rotation and secure holding.
Solution Approach 2:
The lock plate is positioned to engage with the engagement protrusions before the device can move from the locked position. This preliminary engagement prevents unintended movement or slippage during device operation, ensuring that the device remains securely held while still allowing easy rotation when the lever is activated.

AI summary
An electronic device support stand is a support stand for electronic devices that enables rotating the supported electronic device in a confined space with substantially no force while holding the electronic device securely. The electronic device support stand has a holding unit configured to hold an electronic device; and a base unit that supports the holding unit. The holding unit includes a pivot mechanism enabling rotating the supported electronic device with substantially no load around an axis parallel to the surface on which the base unit is placed.
