Equipment Stand Tray Latching for Preset Angle Recall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional equipment stands require users to repeatedly adjust and lock their angular position, making it difficult to maintain a preferred setting, and often necessitate significant force and complex steps during setup.
Innovation Solution
A stand assembly with a rotatable tray member and angular setting mechanism that remembers the user's desired position, using a latching mechanism to maintain the setting and a snap button device to prevent rotation, allowing easy setup and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional equipment stands are made angularly adjustable, then the user can configure the stand in different angular positions, but the preferred angular position is not remembered when the stand is collapsed, requiring repeated adjustment each time
Solution Approach 1:
The latching mechanism is pre-configured with multiple angular position settings along the post member. When the tray member is rotated to a desired angle, the latching mechanism automatically engages with the corresponding position, preliminarily establishing the angular configuration before the user needs to use the stand again. This eliminates the need for repeated adjustment.
Solution Approach 2:
The latching mechanism automatically maintains the selected angular position without requiring user intervention. When the tray member is rotated to a desired angle, the latching mechanism self-activates to lock the position, and when collapsed, the mechanism self-maintains the angular setting information, serving itself to remember the configuration.
2Stability of the object's composition
If conventional equipment stands use a locking mechanism to maintain angular position, then the stand can hold its setting, but a significant amount of force is required to lock the stand into the desired position
Solution Approach 1:
The latching mechanism acts as an intermediary between the tray member and the post member. Instead of requiring direct user force to maintain the angular position, the latching mechanism mediates the connection, using its own internal spring-loaded engagement system to hold the tray member at the desired angle with minimal user effort.
Solution Approach 2:
The latching mechanism uses periodic engagement and disengagement cycles. A spring-loaded detent engages with notches at specific angular intervals, creating periodic stable positions. This allows the stand to maintain stability at discrete angles without requiring continuous force application.
3Measurement precision
If conventional equipment stands use multiple adjustment steps to set the angular position, then precise positioning can be achieved, but a series of elaborate steps must be carried out each time the stand is used
Solution Approach 1:
The angular adjustment range is segmented into multiple discrete position settings along the post member, with each segment corresponding to a specific angular configuration. The latching mechanism engages with these segmented positions, providing precise angular control while simplifying the adjustment process to a single rotation action rather than multiple steps.
Solution Approach 2:
Multiple angular position settings are pre-established along the post member at common viewing angles. The latching mechanism is pre-configured to engage with these predetermined positions, so the user only needs to rotate the tray member to the desired pre-set angle without performing multiple adjustment steps.

AI summary
A stand assembly for supporting an object in a cantilevered manner above a surface is disclosed herein. The stand assembly includes a post member; a tray member coupled to the post member, the tray member configured to be rotatable between an active position for supporting the object and a collapsed position; an angular setting mechanism configured to set a user-desired angular position of the tray member relative to the post member; and a latching mechanism configured to maintain the tray member in the active position when engaged with the tray member by preventing a rotation of the tray member. The user-desired angular position setting of the tray member is maintained when the tray member is rotated from the active position to the collapsed position so that the tray member generally returns to the user-desired angular position when the tray member is rotated from the collapsed position to the active position.
