Ergonomic Handheld Luggage Scale with Top Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luggage scales are often difficult to use safely, as they require lifting heavy luggage, may have uncomfortable handles, and do not allow for easy two-handed operation, leading to potential back injuries and inconvenience in measuring luggage weight before travel.
Innovation Solution
A handheld electronic luggage scale with a horizontally held handle, a vertically extending hook, and a digital display on top, providing ergonomic support and allowing one or two-handed operation, enabling safe lifting and easy weight measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If known portable electronic scales are used, then weight measurement can be performed, but they require lifting heavy luggage which may cause back injuries
Solution Approach 1:
The scale is divided into two functional parts: a handheld portion containing the electronic scale component and a separate hook portion. This segmentation allows the user to hold only the lightweight handle while the hook suspends the luggage, eliminating the need to lift heavy weights with the user's body.
Solution Approach 2:
The hook acts as an intermediary element between the luggage and the electronic scale component. It transfers the weight of the luggage to the scale mechanism without requiring the user to directly lift or support the full weight, thereby preventing back injuries.
2Ease of operation
If known scales have handles, then they can be held, but the handles are uncomfortable to hold and do not allow two-handed operation
Solution Approach 1:
The handle is designed with dynamic adaptability to accommodate different user preferences and situations. It can be effectively operated with one hand or two hands, and the curved downward design naturally guides the user's hand position for optimal comfort and control during weighing operations.
Solution Approach 2:
The handle features a curved downward configuration from the central portion to the ends, creating an ergonomic shape that fits naturally in the user's hand(s). This curvature provides comfortable grip and allows for stable holding position whether using one or two hands.
3Measurement precision
If known scales require lifting luggage high up, then weight can be measured, but it causes inconvenience and potential injury
Solution Approach 1:
The scale design maintains the display and measurement function at a consistent, easily accessible position relative to the user. The hook is positioned at the end of the handle, allowing the display to remain in a convenient viewing position without requiring the user to lift the luggage or scale to excessive heights.
4Ease of operation
If the display is positioned on the handle, then weight reading is visible, but the handle design must accommodate both display visibility and lifting mechanics
Solution Approach 1:
The display is positioned on the top surface of the handle, utilizing the vertical dimension to provide visibility. The handle is designed to be held horizontally, with the display oriented upward, allowing the user to view the weight reading without compromising the lifting mechanics or requiring additional complex structural elements.
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 design facilitates safe and comfortable lifting of luggage by distributing weight evenly and allowing easy viewing of the weight measurement, reducing the risk of back strain and improving user convenience.

AI summary
A hand-held electronic luggage scale includes a handle designed to be held generally horizontally, and a hook supported by the handle, which extends generally vertically below the handle. The handle houses an electronic scale, the electronic scale connected to the hook for calculating a weight of an object suspended from the hook. The hook may be metal and have a rubber and/or plastic exterior. A touch screen display may be provided in a top surface of the handle that displays the calculated weight from the electronic scale component. The touch screen display may include an icon representing a virtual control button that controls a user-selectable setting, and provides haptic feedback when the user-selectable setting changes due to a user pressing the virtual control button for a predetermined period of time. The touch screen display may include icons that control power, illumination, units of measurement, and/or other functionality.
