Solution Overview

Problem

Conventional lift handles on receptacles, particularly trash cans, suffer from structural failure due to excessive stress, premature wear, and lack of ergonomic design, leading to reduced durability and user discomfort.

Innovation Solution

A lift handle design featuring side supports with outer and inner walls, a hand grip, and reinforcing elements that distribute load and enhance ergonomic comfort, integrated into the receptacle's sidewall, using materials resistant to environmental factors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional lift handles are used on receptacles, then the basic lifting function is provided, but the handles are prone to structural failure due to excessive stress and bending

Engineering Contradiction:

Improvestructural integrity of lift handleVSAvoiddurability of lift handle

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The lift handle is divided into multiple components: a first side support, a second side support, and a hand grip portion. Each component has specific structural features (outer walls, inner walls, connecting walls) that distribute and manage stress independently, preventing single-point failure and enhancing overall structural integrity and reliability.

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If simple attachment methods are used for lift handles, then manufacturing is easier, but the handles detach from the receptacle due to excessive stress at attachment points

Engineering Contradiction:

Improvesimplicity of handle attachmentVSAvoidattachment durability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The handle assembly is segmented into side supports and hand grip portions that can be separately manufactured and then attached to the receptacle. This segmentation allows for optimized attachment designs at each interface while maintaining manufacturing efficiency, reducing stress concentration at attachment points and preventing detachment.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If non-ergonomic lift handles are used, then manufacturing is simpler, but user comfort is reduced and proper use is limited

Engineering Contradiction:

Improveuser comfortVSAvoidhandle structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The hand grip portion is designed with specific ergonomic qualities including a curved shape and positioned between the side supports to fit the user's hand comfortably. This localized ergonomic design enhances ease of operation without requiring complete redesign of the entire handle structure, maintaining a balance between comfort and manufacturing complexity.

Inventive Principle:

Principle #3Local quality

AI summary

An improved lift handle for receptacles, designed to significantly enhance durability and user comfort, is provided. The lift handle includes a structural configuration with dual side supports, each comprising an outer and an inner wall joined together by a connecting wall. This design effectively distributes the load during use, minimizing common issues such as bending, deforming, and cracking. Additionally, the handle features an ergonomically designed hand grip with a U-shaped cross-section and apertures for fluid drainage, providing a comfortable and secure grip for the user. This lift handle can extend the service life of the receptacle and can promote more efficient use of the receptacle by reducing the need for frequent replacements and facilitating handling of the receptacle.
