Corner-Mounting Fixators for Portable Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting apparatuses for portable terminals often fail to securely hold devices of varying sizes and shapes, leading to accidental button engagement and inconvenience, as they typically rely on side or surface mounting which can result in unintended function activation.
Innovation Solution
An apparatus with four moveable fixators that can adjust diagonally to securely attach to the corners of portable terminals, utilizing a controller for detection and motorized movement, and can be shaped to fit different devices, including soft materials for compatibility and ease of replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the portable terminal is mounted by holding it at a side surface or upper/lower surface, then the mounting structure is simple, but the buttons on the side surface or upper/lower surface may be accidentally engaged and cause unwanted functions to be performed
Solution Approach 1:
The patent transitions from mounting the portable terminal on its side surface or upper/lower surface to mounting it on its corner portions. This dimensional change in the mounting location eliminates the problem of accidental button engagement while maintaining a relatively simple mounting structure. The corner portions are positioned away from the button areas, so the mounting action does not interfere with button operation.
Solution Approach 2:
The patent introduces corner portions as intermediary mounting points between the terminal body and the mounting apparatus. These corner portions serve as dedicated attachment points that are spatially separated from the button regions, allowing secure mounting without interfering with button functionality. The corner portions act as mediators that enable mounting while preventing harmful side effects.
2Device complexity
If the cradle is designed for a specific size portable terminal, then the mounting structure is simple, but it cannot mount portable terminals of various sizes and shapes
Solution Approach 1:
The mounting apparatus is designed with four independently movable fixators that can be positioned at different locations on the cradle. This universal design allows the same mounting structure to accommodate portable terminals of various sizes and shapes by adjusting the positions of the fixators. The corner portion mounting approach works for different device dimensions, making the cradle multi-functional rather than size-specific.
Solution Approach 2:
The fixators are designed to be movable rather than fixed, allowing dynamic adjustment of their positions. Each fixator can move to appropriate locations to match different terminal sizes and shapes. This dynamic capability enables the mounting structure to adapt to various devices without requiring multiple specialized cradles, resolving the contradiction between structural simplicity and adaptability.
3Reliability
If four fixators are used to fix corner portions of the portable terminal, then the portable terminal is securely mounted without accidental button engagement, but the device complexity increases
Solution Approach 1:
The mounting apparatus is segmented into four independent fixators rather than using a single complex mounting mechanism. Each fixator independently performs the mounting function at one corner portion of the terminal. This segmentation simplifies the individual components while achieving secure mounting through their combined action, reducing overall system complexity despite the increased number of elements.
Solution Approach 2:
The four fixators work together in unison to achieve secure mounting of the portable terminal. By combining the simple actions of multiple fixators moving to corner portions, the system achieves reliable mounting without accidental button engagement. The merging of multiple simple components creates a robust mounting solution that is more reliable than a single complex mechanism.

AI summary
An apparatus for mounting a portable terminal is provided and may include a plurality of fixators configured to move in diagonal directions of one surface of the portable terminal and fix corners of the portable terminal. A controller is configured to detect the portable terminal and execute the movement of the fixators so that the fixators closely adhere to the corners of the portable terminal.
