Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide-type handheld electronic devices lack a mechanism to securely fix the relative positions of their sliding bodies, affecting user experience and potentially leading to instability during sliding operations.
Innovation Solution
Incorporating a locating member with an elastic portion and a sliding portion that fits into locating openings at the ends of the slide surface, allowing for precise positioning and improved sliding smoothness through the use of low friction layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a slide-type structure is used to provide larger screen and key area, then the device functionality is improved, but the stability of relative positions between bodies deteriorates
Solution Approach 1:
The locating member is pre-configured with elastic prestress before the sliding operation. This preliminary elastic energy storage enables the locating member to automatically engage with the locating opening when the sliding body reaches the end position, thereby preliminarily preparing the positioning mechanism to ensure stable relative positioning without affecting the sliding functionality.
Solution Approach 2:
The locating member acts as an intermediary element between the sliding body and the stationary body. It mediates the positioning relationship by engaging with the locating opening, transferring and maintaining the relative position information, thereby ensuring stability while allowing the sliding mechanism to function freely during the sliding process.
2Ease of operation
If friction reduction measures are applied to improve sliding smoothness, then the ease of operation is improved, but the manufacturing complexity increases
Solution Approach 1:
The friction coefficient between the sliding body and stationary body is changed by applying a low friction layer coating on the contact surfaces. This parameter change in surface properties reduces sliding resistance and improves sliding smoothness. The coating process is a standard manufacturing technique that adds minimal complexity while achieving the desired friction reduction.
