Perpendicular Axis Sliding Housing for Portable Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding-type portable terminals are limited in their ability to facilitate the use of diverse functions due to their fixed horizontal or vertical opening/closing mechanisms, making them inconvenient for certain services like broadcasting watching or game playing that require specific key manipulations.
Innovation Solution
A portable terminal design featuring a second housing that slides about an axis perpendicular to the top face of a first housing, utilizing a guide groove and elastic member to sequentially open and close portions of the top face, allowing for diverse sliding positions to accommodate various functions, such as voice communication, data input, and multimedia usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional sliding-type terminals use fixed horizontal or vertical opening/closing mechanisms, then the structure is simple and reliable, but the terminal cannot conveniently facilitate diverse functions like broadcasting watching or game playing that require specific key manipulations
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed sliding mechanism into a movable and adjustable one. The second housing can be positioned at multiple locations along the guide groove, allowing the opening/closing configuration to change dynamically based on the desired function. This enables the terminal to adapt between different usage modes (voice communication, data input, multimedia) without requiring multiple dedicated devices.
Solution Approach 2:
The patent segments the top face of the first housing into multiple regions (first region, second region, third region) that can be selectively exposed by positioning the second housing at different locations. This segmentation allows different functional areas to be accessed independently, enabling diverse functions to be facilitated by exposing only the necessary regions for each specific task.
2Adaptability or versatility
If the second housing translates about an axis perpendicular to the top face of the first housing to sequentially open portions of the top face, then diverse functions can be facilitated, but the sliding mechanism becomes more complex compared to straight sliding
Solution Approach 1:
The patent introduces a guide groove as an intermediary element that simplifies the complex sliding motion. The guide groove, formed in the guide plate mounted in the second housing, provides a predetermined path that guides the guide protrusion during rotation. This intermediary structure converts the complex rotational movement about a perpendicular axis into a controlled sliding motion along a defined trajectory, making the mechanism more manageable and reliable.
Solution Approach 2:
The elastic member (spring) provides self-service by automatically returning the second housing to its initial position after it has been moved to a different location along the guide groove. This eliminates the need for additional motors or actuators to reset the housing position, simplifying the mechanism while maintaining the ability to access multiple functional configurations.
3Reliability
If conventional terminals maintain sufficient distance between transmitting unit and receiving unit, then communication function is reliable, but the terminal size cannot be miniaturized
Solution Approach 1:
The patent utilizes the third dimension (depth/layering) by stacking functional components within the housing structure. The transmitting unit and receiving unit are positioned in different spatial layers, allowing them to maintain sufficient distance for reliable communication while the overall terminal volume is reduced through vertical arrangement rather than horizontal expansion.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient use of multiple terminal functions by allowing the user to select optimal opening/closing configurations for different services, enhancing usability and functionality beyond traditional straight sliding mechanisms.
Implementation Method 1
an elastic member whose one end is supported by the guide protrusion and the other end is supported by the support protrusion. The elastic member provides a driving force for moving the guide protrusion to a vertex portion of the locus of the guide groove

AI summary
Provided is a portable terminal including a first housing and a second housing combined with the first housing while facing the first housing. The second housing translates about an axis perpendicular to a top face of the first housing while facing the first housing, thereby sequentially opening portions of the first housing and sequentially closing already opened portions of the first housing, thereby increasing diversification in use of the portable terminal. Portions of the first housing are sequentially opened or closed, thereby allowing a user to select a position of the second housing according to a desired function such as voice communication, mail writing, or broadcasting watching.
