Pivot Stand Assembly for Tablet Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tablet computer stands are cumbersome, cause neck and shoulder discomfort due to fixed operation modes, rely on springs that fatigue, and have high production costs due to non-shareable molds, and inefficient packaging.
Innovation Solution
A stand assembly comprising a base and multiple interconnected stand units with pivotally connected shafts and holes, allowing adjustable angles without spring torque, and shared molds for cost reduction and compact packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring is utilized as a fixed point around which torque is generated in the stand, then the stand can provide support and positioning, but the spring may become elastically fatigued after prolonged use
Solution Approach 1:
The patent removes the spring component from the stand structure entirely. Instead of using a spring as the fixed point for torque generation, the invention uses a simple pivot connection between the stand and the electronic device body, eliminating the elastic element that would fatigue over time.
Solution Approach 2:
The patent employs a simple pivot connection with a fixed point that does not rely on elastic materials. This approach uses durable, non-consumable components that do not degrade through repeated use, effectively replacing the spring with a more reliable mechanical connection.
2Manufacturing precision
If the stand is designed with non-shareable molds for parts, then the stand can achieve specific structural requirements, but the production cost becomes high
Solution Approach 1:
The patent designs the stand components with universal features that allow the same molds to be used for producing different parts. The stand unit, base, and connecting components are designed with standardized geometries that can be manufactured using shared molds, reducing tooling costs while maintaining structural precision.
3Stability of the object's composition
If the stand is designed with large overall size to provide stable support, then the support stability is improved, but the package space is wasted
Solution Approach 1:
The patent designs the stand to fold flat against the electronic device body when not in use. The stand unit can be stored within or alongside the device housing, allowing compact packaging without sacrificing the stand's stability when deployed. The stand extends to provide support only when needed.
Solution Approach 2:
The patent creates a dynamic stand structure that can transition between a compact folded state for storage and packaging, and an extended stable state for use. The pivot connection allows the stand to adapt its configuration, providing stability when deployed while minimizing space when stored.
4Device complexity
If the touch panel is placed horizontally only, then the device structure is simple, but users experience neck and shoulder discomfort
Solution Approach 1:
The patent implements a dynamic stand with a pivot connection that allows the electronic device to be positioned at multiple angles. The stand can be adjusted to provide horizontal, lateral, or leaned configurations, enabling users to find comfortable viewing angles while maintaining a relatively simple overall device structure.
Solution Approach 2:
The patent separates the device into a main body and a detachable stand unit connected by a pivot. This segmentation allows the stand to provide multi-angle positioning capability without complicating the main device structure, as the angular adjustment function is isolated to the stand component.
5Ease of operation
If the stand is designed to be easily fixed, then the operation convenience is improved, but the stand tends to slide
Solution Approach 1:
The patent incorporates a tightening portion on the stand that can be engaged with a corresponding structure on the device body to pre-establish a secure connection. This preliminary fixing action ensures the stand is firmly attached before use, preventing sliding while maintaining ease of operation through simple engagement and disengagement mechanisms.

AI summary
Stand assembly includes base and first and second stand units. The first stand unit includes first body and extending portion. The first body has first and second ends and first shaft. The extending portion connects the first body and has first shaft hole having first hole portion and second hole portion communicated with each other. The first shaft is pivotally connected to the base. The second stand unit includes second body having third end and second shaft. The second shaft is pivotally connected to the first or second hole portion, selectively. When the second shaft is pivotally connected to the first hole portion, the third end abuts against the second end. When the second shaft is pivotally connected to the second hole portion, the third end leaves the second end, so the second stand unit can rotating relative to the first stand unit.
