Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional household electronic scales have a large unfolded area, making them prone to damage and are cumbersome due to their size, and existing folding scales remain thick after folding, complicating portability.
Innovation Solution
A folding weight scale with two steel frames connected by a rotating connection component, utilizing a conductive coil and aluminum-iron-boron magnet block for stability during use, and detachable components for easy storage and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the scale uses a large unfolded area for convenient measurement, then measurement convenience is improved, but portability and resistance to damage deteriorate
Solution Approach 1:
The scale is divided into two separate steel frames that can be used independently or combined. Each frame can function as a standalone scale, providing measurement convenience while reducing the size and vulnerability of each individual unit compared to a single large-scale design
2Ease of operation
If the scale is designed to fold in half, then portability is improved, but thickness and compressibility increase
Solution Approach 1:
Instead of folding a single frame in half which increases thickness, the design segments the scale into two separate frames that can be detached and stored independently, maintaining a compact form without the thickness penalty of folding
3Ease of operation
If the scale structure is made detachable for easy storage, then storage convenience is improved, but structural complexity increases
Solution Approach 1:
The scale consists of two detachable steel frames that can be separated for storage. This segmentation provides easy storage convenience while keeping the structural complexity manageable through simple connection and separation mechanisms
Solution Approach 2:
The rotating connection component enables dynamic adjustment between connected and detached states, allowing the frames to rotate and lock into position, providing both stability during use and ease of detachment for storage
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
Ensures stability during weighing while allowing easy folding and detachment for compact storage, enhancing user-friendliness and reducing damage risk.
Implementation Method 1
A magnetic field will be generated by energizing the above said conductive coil which then will be adsorbed by and fixed with the aluminum-iron-boron magnet block
Implementation Method 2
when an object is placed on the scale, a pressure will be applied to the sensors, which deform, resulting in changed impedance and at the same time, changed excitation voltage, outputting a changed analog signal
