Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs face challenges in maintaining effective wireless communication due to interference from external radio waves, as metal components in the housing can block or disrupt wireless signals, and there is a lack of measures to address this issue specifically in battery packs.
Innovation Solution
A battery pack design that includes a transmissive portion in the housing to allow radio wave transmission and a protection mechanism in the battery monitoring and control apparatuses to safeguard battery information during wireless communication, ensuring accurate data transmission and reception without external radio wave interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal components are used in the housing for structural strength and protection, then strength and protection are improved, but wireless communication is blocked or disrupted
Solution Approach 1:
The housing is segmented into metal portions and non-metallic portions, allowing different materials to serve different functions. The non-metallic portions are strategically placed to enable radio wave transmission while metal portions provide structural strength and protection.
Solution Approach 2:
Different portions of the housing have different material properties tailored to local requirements. Non-metallic materials are used specifically in areas where wireless communication occurs, while metal materials are used in areas requiring structural strength, creating local quality variations that resolve the contradiction.
2Loss of information
If wireless communication is enabled for data transmission, then information exchange is improved, but vulnerability to external radio wave interference increases
Solution Approach 1:
Error correction codes act as an intermediary mechanism between the transmitted data and potential interference. These codes detect and correct errors caused by external radio wave interference, ensuring accurate data reception despite the presence of harmful factors.
Solution Approach 2:
Error correction codes are incorporated into the data transmission protocol in advance, before interference occurs. This preliminary preparation enables the system to automatically detect and correct errors caused by external radio waves, preventing information loss.
3Reliability
If transmissive portions are added to the housing for radio wave transmission, then wireless communication is improved, but housing protection and structural integrity are reduced
Solution Approach 1:
The housing structure is divided into load-bearing metal sections and non-load-bearing non-metallic sections. The non-metallic portions serve as transmissive areas for radio waves while the metal sections maintain structural integrity, allowing both functions to coexist without compromising overall strength.
