Mobile Terminal Support With Inclined Abutment Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing universal mobile terminal supports fail to securely hold devices of varying widths and thicknesses while maintaining unobstructed access to the front face, and they do not adequately address safety and vibration issues during impacts.
Innovation Solution
A support with a trapezoidal cavity defined by a flat bearing surface and an inclined abutment surface forming an acute angle, combined with a flexible inner coating and a lateral retaining device featuring leaf springs, allows for secure retention of mobile terminals of different sizes without obstructing access to the front face, and enhances safety by dampening vibrations and securing the device during impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If elastic side tabs are used to press against the edges of the telephone, then the support can adapt to mobile terminals of different widths and thicknesses, but the tabs hinder access to the front of the phone
Solution Approach 1:
The patent removes the obstructive tabs from the support structure entirely. Instead of using tabs that press against the edges, the invention uses a cavity with inclined abutment surfaces that guide and retain the terminal without protruding elements, thus eliminating the obstruction to front face access while maintaining adaptability to different dimensions
Solution Approach 2:
Rather than having protruding tabs press outward against the terminal edges, the patent inverts the approach by using inward-sloping abutment surfaces within the cavity that passively guide the terminal into position and retain it through the inclination angle, achieving retention without obstruction
2Adaptability or versatility
If a universal support is designed to accommodate different heights, widths and thicknesses, then compatibility with different models is improved, but the ability to securely retain terminals during impacts deteriorates
Solution Approach 1:
The patent uses a fixed inclination angle parameter for the abutment surfaces (between 10° and 45°) that creates reliable retention across varying terminal dimensions. This angular parameter provides consistent mechanical advantage for retention security while the cavity geometry adapts to different heights, widths and thicknesses
Solution Approach 2:
The support combines a rigid outer shell structure with a flexible inner covering material. The rigid shell provides structural integrity and impact resistance, while the flexible inner material allows adaptation to different terminal dimensions and provides cushioning, achieving both universality and reliable retention during impacts
3Adaptability or versatility
If the cavity is made larger to accommodate thicker terminals, then compatibility with different thicknesses is improved, but the stability of terminal retention deteriorates
Solution Approach 1:
The patent transitions from relying solely on horizontal cavity width to accommodate thickness variations, to using the vertical dimension through inclined abutment surfaces. The inclination angle creates a mechanical wedging effect that provides stable retention in the longitudinal direction, allowing the cavity to accommodate different thicknesses without compromising stability

AI summary
This support is a support for a mobile terminal, such as a mobile telephone or a smartphone, the terminal having a generally long parallelepipedal shape comprising two opposite faces framed by edges. The support comprises a base (12) defining an open space (14) for receiving a mobile terminal. The base (12) comprises a plane bearing surface (16) designed to support a face of the mobile terminal, and a cavity (18) for receiving an edge of the mobile terminal. The cavity (18) is defined between a peripheral region of the bearing surface (16) and a plane abutment surface (20) designed to support the edge of the mobile terminal in a longitudinal direction (L). The abutment surface (20) faces the bearing surface (16) and is inclined with respect to the bearing surface (16), forming an acute angle with the bearing surface (16).
