Solution Overview

Problem

Existing attachment instruments for electronic devices with directivity antennas have limited angle adjustment ranges due to a single set of round and arc-shaped holes, necessitating increased size to enhance adjustment capabilities.

Innovation Solution

The use of two arc-shaped long holes in a first plane with two axes, where one axis is fixed and the other moves, allows for dual-axis adjustment without increasing the instrument's size, enabling broader angle adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the size of the arc-shaped long hole is increased to enlarge the angle adjustment range, then the angle adjustment range is improved, but the size of the attachment instrument is increased

Engineering Contradiction:
Improveangle adjustment rangeVSAvoidsize of attachment instrument
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The attachment instrument is segmented into multiple independent angle adjustment mechanisms. Each mechanism includes a round hole and an arc-shaped long hole, providing separate rotation axes. By dividing the adjustment function into multiple segments, the patent achieves a broader total adjustment range without requiring each individual arc-shaped long hole to be excessively large, thus controlling the overall instrument size.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If only one set of round hole and arc-shaped long hole is provided, then the structure is simple, but the angle adjustment range is limited

Engineering Contradiction:
Improveangle adjustment rangeVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple angle adjustment mechanisms (each consisting of a round hole and an arc-shaped long hole) are merged into a single attachment instrument. The first and second round holes work together with the first and second arc-shaped long holes to provide combined azimuth and elevation adjustment capabilities, achieving a broader adjustment range while maintaining relatively simple individual component structures.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The attachment instrument is designed with multi-functionality by incorporating multiple adjustment mechanisms that can handle different rotation axes. The same basic structure of round hole and arc-shaped long hole is reused for different angular adjustments, allowing the instrument to perform multiple adjustment functions without proportionally increasing complexity.

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

AI summary

An attachment instrument for an electronic device (10) includes a first angle adjustment part (30) configured to adjust an orientation of an antenna included in the electronic device (10) by two arc-shaped long holes (31a, 31b) formed in a plane and two axes (32a, 32b) moving inside the two long (31a, 31b), respectively. The first angle adjustment part (30) makes the adjustment by the axis (32a) inside one of the long holes (31a) being fixed and the axis (32b) inside the other one of the long holes (31b) being allowed to move.
