Spring-Loaded Device Stand for Stable Viewing Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stands for portable electronic devices do not effectively allow for convenient viewing orientations without continuous user involvement, particularly on horizontal surfaces, and lack improved features to maintain devices at preferred angles.
Innovation Solution
A protective case system with a stand that includes a base portion, two pivoting legs, and spring arms, allowing the legs to pivot between stowed and extended positions, applying a varying spring force to maintain the device in desired viewing orientations on a horizontal surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stand uses simple static legs, then the structure is simple, but the device cannot maintain stable viewing orientations without user intervention
Solution Approach 1:
The stand employs dynamic spring arms that can pivot and adjust to different angles, transforming a static structure into a dynamic one that automatically adapts to maintain the device in various viewing orientations without requiring continuous user intervention
Solution Approach 2:
The spring arms utilize elastic deformation to change their support parameters, allowing the stand to maintain different viewing angles by adjusting the spring compression and pivot points, thereby achieving multiple stable positions with a single continuous structure
2Ease of operation
If the stand requires continuous user adjustment, then the structure can be simple, but the ease of operation deteriorates
Solution Approach 1:
The spring arms are designed to automatically adjust and maintain the device at preferred viewing angles through their elastic properties, eliminating the need for continuous user intervention and allowing the stand to self-regulate its positioning
Solution Approach 2:
The spring arms are pre-configured with elastic tension that automatically positions the device in optimal viewing orientations when placed on the stand, performing the adjustment action beforehand rather than requiring ongoing user control
3Adaptability or versatility
If the stand uses fixed support points, then the manufacturing is simple, but the adaptability to different viewing orientations is limited
Solution Approach 1:
The spring arms provide movable support points that can pivot at different angles, enabling the stand to accommodate various viewing orientations without requiring multiple fixed support structures, thus achieving versatility through dynamic adjustment rather than manufacturing multiple configurations

Function Achieved in This Case
Enables portable electronic devices to be securely positioned in preferred viewing angles on horizontal surfaces, reducing the need for continuous user involvement and enhancing stability and usability in various environments.
Implementation Method 1
Each pivoting spring arm is configured to apply a spring force to the leg to alternately maintain the leg in the stowed position or in the extended position

AI summary
A stand that is attachable to a back surface of an electronic device or a protective case for the electronic device. The stand includes a base portion, two legs, and two pivoting spring arms. Each leg pivots at a leg axis along an arc between a stowed position and an extended position. The two pivoting spring arms are attached to the base portion at a first end and attached to a respective one of the legs at a second end. Each pivoting spring arm is configured to apply a spring force to the leg to, alternately, force leg toward the stowed position or the extended position depending on the starting position of the leg.
