Solution Overview

Problem

Existing systems for electrically operated hand-held devices, such as hot-air and grinding tools, lack a practical and stackable transport case that allows for easy preparation, use, and storage without requiring auxiliary constructions, and do not facilitate ergonomic handling or reduce thermal damage to the case.

Innovation Solution

A transport case with a depression on its outer side that accommodates the hand-held device, allowing it to be positioned for use or storage without removing auxiliary constructions, and features a design that maintains stackability and stability, with a latching mechanism for secure connection and ergonomic handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the transport case is designed with a depression on the outer side to accommodate the hand-held device, then the ease of operation is improved by allowing the device to be held with both hands, but the device complexity increases due to the additional structural feature

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The transport case is segmented into functional zones: a depression region on the outer side for device accommodation and a storage space region for accessories. This segmentation allows the device to be held securely with both hands while keeping the overall structure relatively simple.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The depression is formed on the outer side surface of the transport case, utilizing the external dimension rather than internal space. This allows the device to be accommodated without reducing the internal storage capacity, resolving the contradiction between operational ease and structural complexity.

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

2Productivity

If the hand-held device is arranged in the depression of the transport case during operation, then the productivity is improved by enabling stable two-handed operation, but the loss of time increases due to the additional setup requirement

Engineering Contradiction:
ImproveproductivityVSAvoidloss of time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The depression is pre-formed on the transport case outer side, so no auxiliary constructions need to be assembled during operation. The device can be directly placed into the depression for immediate two-handed operation, eliminating setup time while maintaining productivity benefits.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the depression is formed in the bottom wall of the case shell, then the ease of operation is improved by providing stable support for the hand-held device, but the volume of the transport case is reduced

Engineering Contradiction:
Improveease of operationVSAvoidvolume
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The depression is formed on the outer side surface (external dimension) of the transport case rather than removing material from the internal storage space. This allows the device to be supported stably while preserving the internal volume for storing accessories and other items.

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

4Adaptability or versatility

If the transport case is designed to accommodate the hand-held device on its outer side, then the adaptability is improved by allowing multiple use scenarios, but the manufacturing precision requirements increase

Engineering Contradiction:
ImproveadaptabilityVSAvoidmanufacturing precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The transport case is divided into distinct functional areas: the depression zone on the outer side for device accommodation and the internal storage space for accessories. This segmentation allows each zone to be optimized independently, providing versatility while using standard manufacturing tolerances for each segment.

Inventive Principle:
Principle #1Segmentation
