Solution Overview

Problem

Conventional hand-held material collecting equipment designs hinder easy and quick attachment or detachment of storage compartments from handles, leading to ergonomic issues for users.

Innovation Solution

A material collecting equipment with a handle and collection basket configuration featuring a hook member that allows the collection basket to be releasably secured to the handle via a cross-member, enabling easy engagement and disengagement by sliding along the mid-plane, with the hook member extending from the handle or cross-member for secure attachment and detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional designs of storage compartment, handle and connection mechanisms are used, then structural stability is maintained, but ease of operation deteriorates making it difficult to attach and detach storage compartment

Engineering Contradiction:
Improveease of attaching and detaching storage compartmentVSAvoidcomplexity of connection mechanisms
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connection mechanism is segmented into distinct functional components: a hook member on the handle and a corresponding engagement feature on the cross-member. This segmentation allows the attachment and detachment operations to be simplified into straightforward mechanical actions while maintaining structural integrity through the distributed connection points.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection mechanism incorporates dynamic elements that allow smooth transition between attached and detached states. The hook member and cross-member engagement features are designed to enable easy engagement through simple sliding or hooking motions, while maintaining secure connection when attached, thus improving ease of operation without requiring complex mechanisms.

Inventive Principle:
Principle #15Dynamics

2Productivity

If conventional connection mechanisms are used, then structural integrity is maintained, but time consumption increases for attaching and detaching operations

Engineering Contradiction:
Improvespeed of attaching and detaching storage compartmentVSAvoidtime for securing and detaching collection basket
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The hook member and engagement features are pre-positioned on the handle and cross-member respectively, allowing the collection basket to be quickly attached by simply engaging these pre-configured elements. This preliminary configuration eliminates the need for complex assembly operations during attachment or detachment, significantly reducing time consumption while maintaining secure connection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of requiring complex locking mechanisms that take time to operate, the design inverts the approach by using simple hook-and-engagement features that naturally secure when brought together and release when pulled apart. This inverted logic of connection simplifies the attachment/detachment process to basic mechanical actions, improving productivity without sacrificing structural integrity.

Inventive Principle:
Principle #13The other way round (Inversion)
