Pivoting Stand Mechanism With Switchable Angle Constraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic apparatus with a stand biased towards its lower end portion lacks an angle controlling mechanism, leading to instability and inconvenience when adjusting the display screen's position, and the stand may obstruct carrying or maintenance operations.
Innovation Solution
A pivoting mechanism with a pivoting angle changing lever that adjusts the pivotal motion permitting angle of the stand with respect to the apparatus body, allowing for controlled angles between 0° and 90°, enabling upright positioning and facilitating carrying or maintenance without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an angle controlling mechanism is provided to allow the stand to pivot within a predetermined angular range, then the stand placement stability is improved, but the stand projects at a predetermined angle and may obstruct carrying or maintenance operations
Solution Approach 1:
The pivot shaft's pivotal motion permitting angle is changed by the lever position. In the first position, it constrains the stand to a predetermined angular range for stable placement. In the second position, it allows the stand to pivot to a flatter configuration, reducing projection and enabling easy carrying and maintenance without obstruction.
Solution Approach 2:
The angular parameter of the pivot shaft is changed between two states. The first state provides a predetermined angular range for stability during use. The second state changes the angle parameter to allow the stand to lie flatter against the apparatus body, eliminating obstruction during carrying and maintenance operations.
2Stability of the object's composition
If the stand is constrained to a fixed angular range, then the placement state is stabilized, but the display screen cannot be adjusted to arbitrary angular positions
Solution Approach 1:
The pivot shaft transitions between two angular constraint states based on lever position. In the first position, it provides a predetermined angular range for stable placement during normal use. In the second position, it changes the angular constraint to allow broader adjustment ranges, enabling the display screen to be positioned at arbitrary angles while maintaining stability through the controlled pivotal motion.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances convenience by allowing stable placement and easy adjustment of the display screen, reduces the risk of the stand obstructing operations, and simplifies the mechanism by eliminating the need for additional control sections.
Implementation Method 1
a spring member configured to provide pivoting force to the stand in a direction in which an end portion of the stand approaches a lower end portion of the apparatus body
