Solution Overview

Problem

Existing holding devices for mobile radios, such as tactical radios, secure the device but limit access to operating elements and batteries, making it difficult to operate the radio under rough conditions like off-road environments.

Innovation Solution

A holding device with a clamping fixture comprising two jaws that securely hold the mobile radio between its sides while allowing full access to the front, top, and bottom, including the battery, via a lever mechanism that applies force for secure clamping without obstructing operational elements, and includes features like non-slipping materials and ventilation structures for cooling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a secure fixture is used to firmly hold the mobile radio under rough conditions, then the reliability of the holding device is improved, but the ease of operation deteriorates due to limited access to operating elements

Engineering Contradiction:
Improvesecure fixtureVSAvoidaccess to operating elements
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The holding device is divided into multiple independent jaws (first jaw, second jaw, third jaw) that can be positioned at different locations on the mobile radio. This segmentation allows each jaw to clamp specific portions of the device while leaving other areas accessible, resolving the contradiction between secure holding and operational access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different jaws are positioned to clamp specific local areas of the mobile radio (left side, right side, front, back) rather than covering the entire device. This local quality approach ensures secure fixation at clamping points while maintaining access to operating elements in unclamped areas.

Inventive Principle:
Principle #3Local quality

2Reliability

If a cup-shaped holder is used to secure the mobile radio, then the reliability is improved, but the ease of operation deteriorates as operating elements become inaccessible

Engineering Contradiction:
Improvesecure holdingVSAvoidaccess to battery and operating elements
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

Instead of a single cup-shaped enclosure, the device uses multiple separate jaws that clamp the mobile radio from different sides. This segmentation leaves the top, bottom, and front areas accessible, allowing users to reach batteries and operating elements while maintaining secure holding through distributed clamping points.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The holding mechanism transitions from a three-dimensional enclosing structure (cup-shaped holder) to a multi-point clamping system that applies force from multiple directions. This dimensional change allows secure holding without complete enclosure, maintaining access to essential components.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If the mobile radio is completely enclosed in the fixture, then the reliability is improved, but the versatility deteriorates as battery replacement and external power connection become impossible

Engineering Contradiction:
Improvesecure fixtureVSAvoidbattery replacement and power connection
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The fixture is segmented into multiple jaws that independently clamp different portions of the mobile radio. This segmentation creates open spaces between jaws, allowing users to access batteries for replacement and connectors for external power connections while the device remains securely held.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The multi-jaw design provides universal access to various operating elements (buttons, connectors, batteries) regardless of their location on the mobile radio. Users can operate the device, replace batteries, and connect external power sources while the radio is clamped, making the fixture adaptable to multiple operational needs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A secure and versatile holding device for a mobile device such as a mobile radio is provided. By clamping the mobile radio between two jaws, a secure fixture of the radio can be achieved. Since all or almost all operational elements such as buttons and connectors are still available, the operation of the mobile radio is not limited or restricted, and the mobile radio can be powered or even charged while the mobile radio is held by the holding device.
