Solution Overview

Problem

Users face discomfort and strain when holding heavy notebook-type computers due to their weight, as existing straps do not adequately protect the user's hand from the device's burden.

Innovation Solution

A strap with a loop portion, connecting portion, and a protecting member that covers the joining area, allowing the user's hand to be protected even when holding a heavy electronic device, by distributing the weight and providing a cushioned surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If a strap is used to hold a heavy electronic device, then the user can support the device weight, but the joining portion and band member may cause discomfort or damage to the user's hand

Engineering Contradiction:

Improveweight support capabilityVSAvoidhand discomfort and potential damage

Core Design Contradiction:

ForceVSObject-affected harmful factors

Solution Approach 1:

The protecting member serves as an intermediary element positioned between the strap's joining portion/band member and the user's hand. It transfers the mechanical load from the hand to the strap structure while protecting the hand from direct contact with potentially harmful joining portions and tension points, thus resolving the contradiction between weight support and hand protection

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The protecting member is pre-installed on the strap at the joining portion and band member areas before the strap is used. This beforehand protection prevents direct contact between the user's hand and the potentially harmful structural elements, cushioning the hand against discomfort and damage while maintaining the strap's weight-bearing function

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Ease of manufacture

If the strap structure is simplified for ease of manufacture, then production cost decreases, but protection coverage for the user's hand may be insufficient

Engineering Contradiction:

Improvestrap production simplicityVSAvoidinadequate hand protection

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The protecting member is divided into multiple sections: a first protecting member covering the joining portion and a second protecting member covering the band member. This segmentation allows each component to be manufactured independently using simple processes, then assembled together to provide comprehensive hand protection, resolving the contradiction between manufacturing simplicity and protection coverage

Inventive Principle:

Principle #1Segmentation

AI summary

A strap is connected to an electronic device and used when the electronic device is held by a user with a user's hand. The strap comprises a loop portion formed of a band member in a loop-like shape, a connecting portion joined to the loop portion and connected to the electronic device, and a protecting member formed to cover a joining portion and a portion of a predetermined region in a bifurcation portion in the band member forming the loop portion, the joining portion being a portion where the connecting portion is connected to the band member and the bifurcation portion bifurcating and extending out from the joining portion, thereby protecting the user's hand.
