Solution Overview

Problem

Conventional hand belts for portable devices interfere with image capturing when an imaging section is present on the device case, making it difficult to hold the device favorably while ensuring uninterrupted image capture.

Innovation Solution

A hand belt design with a first and second mounting section that allows the belt to be detachably mounted on the device, with a belt body structure that includes opening sections to expose the imaging section, ensuring it does not interfere with image capture and providing a secure hold.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the hand belt is arranged around the mounting case to provide secure holding, then the user can hold the device case favorably, but the hand belt obstructs the imaging section and affects image capturing

Engineering Contradiction:
Improveholding comfortVSAvoidimage capture obstruction
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The hand belt is divided into multiple sections: a first hand belt portion that contacts the mounting case, a second hand belt portion that contacts the device case, and a connecting portion that links them. This segmentation allows the belt to wrap around the device without covering the imaging section, thus maintaining both holding comfort and image capture capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hand belt transitions from a simple annular shape to a three-dimensional configuration that follows the contours of the device case and mounting case. By extending along the lateral direction and connecting portions, the belt utilizes the vertical and lateral dimensions to avoid the imaging section area on the back surface

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

2Object-affected harmful factors

If the hand belt is arranged to avoid the imaging section, then image capturing is not affected, but the device case cannot be held favorably by the user

Engineering Contradiction:
Improveimage capture obstructionVSAvoidholding comfort
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The hand belt merges multiple functional portions into a single integrated structure: the first hand belt portion provides contact with the mounting case, the second hand belt portion provides contact with the device case, and the connecting portion links them. This combined structure distributes holding pressure across multiple surfaces while maintaining clear access to the imaging section

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If the hand belt is attached using a mounting case, then the structure provides secure mounting, but the belt body interferes with the imaging section when arranged on the back side

Engineering Contradiction:
Improvemounting securityVSAvoidimage capture obstruction
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The imaging section is effectively extracted from the area covered by the hand belt through strategic routing. The belt is configured to contact only specific portions of the mounting case and device case, deliberately excluding the imaging section area on the back surface, thus removing the interference problem while maintaining mounting security

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A hand belt includes a first mounting section (20) which is mounted on an upper end portion of a terminal body (1), a second mounting section (21) which is mounted on a lower end portion of the terminal body (1), and a belt body (22) which is attached to both side portions of the first mounting section (20) and the second mounting section (21) and has an opening section (26) which is arranged corresponding to the back of the terminal body (1) and exposes an imaging section (10) provided on the back of the terminal body (1). As a result, by the opening section (26) of the belt body (22), the belt body (22) does not affect image capturing by the imaging section (10) so that an image of a photographic subject can be favorably captured by the imaging section 10, and the terminal body (1) can be held reliably and favorably.
