Solution Overview

Problem

Existing mobile measuring systems for vehicles face challenges in efficiently attaching and detaching measuring apparatuses, particularly due to the weight and size of the equipment, which increases the load on operators and requires specialized machinery for handling.

Innovation Solution

The proposed solution involves an item fixture with a fixation member attached to a vehicle's attachment portion and a handle attachment portion for detachable attachment of handles. This setup allows for the easy attachment and detachment of a mobile measuring apparatus, reducing the load on operators and eliminating the need for specialized machinery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a measuring apparatus is mounted on a vehicle to measure external environments, then measurement capability is improved, but the weight and size of the equipment increases the load on operators

Engineering Contradiction:

Improvemeasurement capabilityVSAvoidequipment weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The measuring apparatus is divided into separate components: a fixture that attaches to the vehicle and a handle that can be detached. This segmentation allows the heavy measuring device to be mounted on the vehicle for measurement capability while the handle can be removed to reduce operator load during transport or when measurement is not needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The handle is extracted as a separate detachable component from the main measuring apparatus. This extraction allows the handle to be removed when not needed, reducing the overall weight that operators must handle, while the measuring apparatus remains mounted on the vehicle for when measurement functions are required.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If a measuring apparatus with significant weight is attached to a vehicle, then measurement functionality is improved, but specialized machinery is required for handling

Engineering Contradiction:

Improvemeasurement functionalityVSAvoidhandling complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The handle acts as an intermediary component that simplifies the interaction between operators and the heavy measuring apparatus. By providing a detachable handle with proper attachment mechanisms, operators can manually handle and position the apparatus without requiring specialized machinery, while the handle itself can be detached to reduce handling complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Stability of the object's composition

If a fixed attachment system is used for the measuring apparatus, then stability is improved, but ease of attachment and detachment deteriorates

Engineering Contradiction:

Improveattachment stabilityVSAvoidease of attachment and detachment

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The attachment system is designed to be dynamic rather than fixed. The handle can be attached to and detached from the measuring apparatus, and the fixture can be attached to and detached from the vehicle. This dynamic design allows the system to transition between stable mounted operation and easy transport, resolving the contradiction between stability and ease of attachment.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The attachment system is segmented into multiple detachable connections: the handle attachment to the measuring apparatus and the fixture attachment to the vehicle. This segmentation allows each connection to be optimized for both stability when attached and ease of detachment when needed, rather than requiring a single fixed attachment that compromises both criteria.

Inventive Principle:

Principle #1Segmentation
