Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weight measuring devices face challenges in ensuring reliable communication performance due to interference from consumables that can disrupt wireless communication signals, particularly in environments where radio waves are affected by the presence of consumables or water.
Innovation Solution
The weight measuring device is designed with a communicator antenna positioned on the upper side of the weight measurer, allowing for unobstructed radio wave transmission and reception, and includes a flexible sheet and double-sided tape to maintain watertightness and stability in potentially wet environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is disposed inside the weight measurer, then the device structure is compact, but the communication performance is degraded due to interference from consumables
Solution Approach 1:
The antenna is moved from a two-dimensional plane inside the weight measurer to a three-dimensional position above it, utilizing vertical space to achieve unobstructed radio wave transmission while maintaining compact horizontal footprint
2Reliability
If the antenna is positioned on the upper side of the weight measurer, then radio wave transmission is unobstructed, but the device requires additional structural components
Solution Approach 1:
The antenna support structure is merged with the waterproof housing structure, where the housing itself serves as the mounting platform for the antenna, eliminating the need for separate support components
Solution Approach 2:
The waterproof housing serves multiple functions: it protects internal components from water ingress and simultaneously acts as the mounting structure for the antenna, achieving structural efficiency
3Adaptability or versatility
If the weight measurer is made waterproof, then it can be used in wet environments, but the manufacturing complexity increases
Solution Approach 1:
A flexible waterproof film is used to seal the opening of the weight measurer, providing effective water protection while maintaining manufacturing simplicity through easy installation and sealing processes
