Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support assemblies for pad-type computer devices restrict the tilting range, making it difficult to maintain desired angles for both upright and tablet positions, especially when a touch screen is integrated.
Innovation Solution
A support assembly with a base member, a support unit having a predetermined curvature, guide rails, and an elastic unit that provides an elastic force to maintain the tilting position, allowing the device to tilt between upright and tablet positions by balancing the load through a combination of rolling contact and elastic force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hinge shaft is installed on the rear side of the device main body for tilting, then the device can be tilted, but the stand coupled with the device main body interferes with the device main body, restricting the tilting range
Solution Approach 1:
The support assembly is divided into separate functional components: a base member fixed to the installation surface, a support unit coupled to the device main body, and a guide rail connecting them. This segmentation allows the support unit to reciprocate along the guide rail without the stand interfering with the device main body, thereby expanding the tilting range while maintaining tilting capability.
2Device complexity
If the device main body is supported in a restricted tilting range, then the structure is simple, but it is difficult to support the tilting at desired angles for both upright position and tablet position
Solution Approach 1:
The support unit is designed to reciprocate dynamically along the guide rail as the device main body tilts between upright and tablet positions. This dynamic reciprocation mechanism allows the support assembly to adapt to different tilting angles without requiring a complex multi-component structure, achieving position adaptability with relatively simple design.
Solution Approach 2:
The elastic unit changes its elastic force parameters based on the tilting position to maintain desired angles. The elastic force varies as the support unit reciprocates along the guide rail, enabling the device to be stably supported at both upright position and tablet position as well as intermediate angles, thereby improving position adaptability.
3Ease of operation
If the display panel is disposed in parallel with the installation surface for tablet position, then touch screen use is efficient, but the restricted tilting range prevents maintaining desired angles for upright position
Solution Approach 1:
The support unit reciprocates along the guide rail dynamically as the device transitions between upright and tablet positions. This dynamic adjustment mechanism enables the device to achieve full parallel alignment with the installation surface for optimal touch screen usability while also maintaining the ability to support upright position and intermediate angles, thereby achieving dual position support.
Solution Approach 2:
The elastic unit adjusts its elastic force parameters according to the tilting angle, providing appropriate support force for both tablet position (parallel to installation surface) and upright position. This parameter change capability ensures efficient touch screen usability in tablet mode while maintaining adaptability for upright viewing and typing positions.
