Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing fixtures for electronic devices, such as wearable devices, limit the flexibility of attachment locations and pose a risk of device fall due to open surfaces.

Innovation Solution

A frame-shaped body with an insertion port that opens towards the attachment point, featuring side and end pieces that project away from the frame, and an attachment member like a fastening needle or belt, ensuring the device is securely held and the port remains open for easy access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the fixture uses a fixed attachment design (e.g., wristband or belt holder), then the attachment is simple, but the flexibility to attach to different target parts is limited

Engineering Contradiction:

Improveattachment flexibilityVSAvoidfixture structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fixture employs a universal attachment member design that can be attached to various target parts (fabric, belt, human body) through different attachment methods (piercing, looping, clipping). The frame-shaped body with open insertion port serves multiple attachment scenarios, making the fixture adaptable to different uses without requiring multiple specialized designs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The fixture is divided into distinct functional components: the frame-shaped body (main structure), the attachment member (fastening mechanism), and the insertion port (access point). This segmentation allows each component to be optimized independently while maintaining overall versatility and simplicity.

Inventive Principle:

Principle #1Segmentation

2Reliability

If the fixture uses an open surface design for attachment, then the attachment is easy, but the electronic device may fall from the fixture

Engineering Contradiction:

Improvedevice retentionVSAvoidattachment ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The fixture incorporates protrusions on the inner surface of the frame-shaped body that preemptively prevent the electronic device from slipping or falling. These protrusions create physical interference that counteracts the natural tendency of the device to slide out, ensuring secure retention while maintaining easy attachment through the open insertion port.

Inventive Principle:

Principle #9Preliminary anti-action

3Ease of operation

If the insertion port is closed after attachment, then the device is secure, but the device cannot be easily removed or accessed

Engineering Contradiction:

Improvedevice accessibilityVSAvoiddevice security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The insertion port remains dynamically open throughout the attachment process, allowing the electronic device to be easily inserted and removed at any time. The open design maintains accessibility while the attachment member and frame structure provide the necessary security to prevent falling, creating a balance between ease of operation and device retention.

Inventive Principle:

Principle #15Dynamics

AI summary

The fixture of the electronic device includes a frame-shaped main body part into which the electronic device is fitted, and an attachment member that attaches the main body part to a target part. An insertion port into which an electronic device can be inserted is formed in the main body portion. In a state in which the fixture is fixed to the target part, the insertion port is formed so as to open toward the target part.
