Clamping Handle Mechanism for Carrying Handleless Items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing items without handles, such as documents and food bags, are difficult to carry and require additional bags for containment, leading to environmental pollution and user fatigue, while existing silicone or fabric food bags are prone to deformation and leakage.
Innovation Solution
A clamping handle device with a clamping body and handle components that can be adjusted to different configurations for clamping and carrying items, and a carrying bag made of silicone material with a secure seal and foldable design to reduce environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If items without handles are held by gripping with palm or cradling in arms, then the items can be held, but user fatigue occurs and it becomes difficult to lift or lower items
Solution Approach 1:
The handle device is divided into separate components: a clamping body with clamping portions and handles that can be attached to items. This segmentation allows the handling function to be added to items without handles, enabling easy carrying by gripping the handles rather than holding items in palm or arms.
Solution Approach 2:
The handle device acts as an intermediary between the user and items without handles. By attaching the handle to the item, the user interacts with the handle rather than directly gripping or cradling the item, reducing user fatigue and improving ease of carrying.
2Reliability
If disposable plastic boxes or cartons are used for containing food, then food can be contained, but a large amount of garbage or non-degradable materials is generated
Solution Approach 1:
The invention merges the food containment function (box) with the carrying function (handle device) into a single integrated system. The handle device can be attached to reusable food containers, eliminating the need for disposable boxes and separate plastic bags, thus reducing environmental pollution while maintaining reliable food containment.
Solution Approach 2:
The handle device is designed to be universally attachable to various food containers and items. This multi-functionality allows a single reusable handle device to replace multiple disposable containers and bags, reducing waste while maintaining effective food containment and carrying capabilities.
3Reliability
If recycled food boxes made of hard plastic and glass are used, then food can be contained, but they occupy space and are inconvenient to carry
Solution Approach 1:
The solution separates the food containment function (reusable food container) from the carrying function (handle device). The food container can be compact and lightweight, while the handle device provides the carrying capability. This segmentation allows the container to be optimized for food storage without the bulk of hard plastic or glass, improving convenience while maintaining containment reliability.
4Ease of operation
If extra plastic bags or heat preservation bags are used to carry food boxes, then the boxes can be carried, but environmental pollution is exacerbated
Solution Approach 1:
The invention merges the carrying function into the food container system itself through the attachable handle device. This eliminates the need for separate plastic bags or heat preservation bags, providing carrying capability while reducing environmental pollution.
Solution Approach 2:
The handle device serves multiple functions: it provides carrying capability, can be attached to various container types, and eliminates the need for additional plastic bags. This multi-functionality addresses the carrying need while reducing environmental pollution.
5Adaptability or versatility
If silicone or fabric food bags are used, then they can hold food, but they are prone to deformation and leakage
Solution Approach 1:
The solution separates the food contact function (food bag) from the structural support function (handle device). The food bag can be made of flexible silicone or fabric for adaptability, while the rigid handle device attached to it provides structural support to prevent deformation and leakage, maintaining both versatility and reliability.
6Reliability
If silicone or fabric food bags require multiple folds to seal the opening, then the opening can be closed, but it is time-consuming and often results in an ineffective seal
Solution Approach 1:
The handle device structure acts as an intermediary that provides a rigid framework for sealing the food bag opening. This structural support enables more effective and quicker sealing mechanisms (such as clips, latches, or structured folds) compared to trying to seal flexible material alone, reducing both time and improving seal effectiveness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The clamping handle device provides stable and ergonomic carrying, while the carrying bag ensures leak-proof and upright storage, reducing waste and enhancing user convenience.
Implementation Method 1
A torsion spring is disposed on the pivot shaft, with two ends respectively abutting against the first clamping portion and the second clamping portion
Implementation Method 2
the first handheld portion and the second handheld portion are hingedly coupled about a hinge joint

AI summary
A clamping handle device includes a clamp body with pivotally connected first and second clamping portions biased by a torsion spring towards a closed position. The clamp body defines a clamping mouth on the opposite side of the torsion spring. First and second handles slide relative to the clamping body and positioned on opposite sides of the clamping mouth. Each handle has hinged first and second handheld portions. The second handheld portions can be rotated to separate the ends of the first and second clamping portions to open the clamping mouth. The clamping handle device is integrated into a carrying bag with detachable sidewalls, and also functions as an electronic device stand.
