Casing Angle Adjustment Mechanism With Sliding Leg Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing casing angle adjustment mechanisms for electronic devices, such as desktop telephones, are complicated to operate due to the need for the hook of the lock arm to rotate on a round path, making it difficult to adjust the angle of the casing with respect to the mounting surface.
Innovation Solution
A casing angle adjustment mechanism featuring a slide plate with engagement grooves and a leg unit with corresponding engagement holes, where a stopper is used to facilitate simple angle adjustments by sliding and rotating the leg unit relative to the casing, allowing the slide plate to block engagement holes and grooves, enabling easy angle changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hook of the lock arm rotates on a round path to adjust the casing angle, then the casing angle can be adjusted and fixed at multiple positions, but the operation becomes complicated
Solution Approach 1:
The round path is segmented into discrete latching positions with latching parts formed at intervals. The hook latches into specific latching parts rather than continuously rotating, dividing the continuous rotation into discrete, easily selectable positions that simplify user operation while maintaining multiple angle adjustment capabilities
Solution Approach 2:
The lock arm acts as an intermediary mechanism between the user's simple rotational input and the casing angle adjustment. By rotating the lock arm, the hook moves along the round path and latches into different latching parts, indirectly achieving casing angle adjustment through this intermediate component

AI summary
A casing angle adjustment mechanism capable of adjusting the angle of a casing with respect to a mounting surface by a simple operation of a leg unit is provided. When an angle adjustment mechanism of a casing rotates a leg unit in one direction, moves a part of a stopper along a connection hole of the leg unit, and slides a slide plate, a side wall of the slide plate blocks openings of engagement holes of the leg unit, and a side wall of the leg unit blocks openings of engagement grooves of the slide plate, and when it rotates the leg unit in another direction, moves the part of the stopper along the connection hole of the leg unit, and slides the slide plate, engagement grooves of the slide plate and engagement holes of the leg unit are placed to overlap.
