Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire monitoring devices with soldered conducting terminals face vibration-induced loosening or disconnection, leading to data access failures, complicating design, increasing manufacturing costs, and occupying internal space.
Innovation Solution
A terminal encapsulated tire monitoring device with conducting terminals partially embedded in the housing, ensuring secure positioning and connection to a circuit board, using injection molding or ultrasonic welding for embedding, and allowing for compact design and extra space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conducting terminals are directly soldered to the circuit board and suspended in the housing, then electrical connection is achieved, but the terminals are prone to vibration-induced loosening or disconnection
Solution Approach 1:
The conducting terminals are integrated with the housing as a unified structure, eliminating the need for separate support means. The terminals are embedded directly into the housing body, merging the housing and terminal functions into a single component that prevents vibration-induced loosening while simplifying the overall design.
Solution Approach 2:
The conducting terminals are pre-positioned and fixed within the housing during the housing manufacturing process. This preliminary positioning ensures that the terminals are correctly aligned and secured before assembly, preventing subsequent loosening or disconnection issues without requiring additional support structures.
2Stability of the object's composition
If support means are added to hold the conducting terminals in position, then terminal positioning is improved, but the design becomes complicated and manufacturing cost increases
Solution Approach 1:
The housing structure is designed to inherently support and position the conducting terminals through its integrated geometry. The housing body itself serves as the positioning mechanism, eliminating the need for separate support means and maintaining manufacturing simplicity while ensuring terminal stability.
Solution Approach 2:
The housing incorporates localized structural features such as recesses, grooves, or embedded channels at specific locations where the conducting terminals need support. These localized structural modifications provide precise terminal positioning without adding overall design complexity or manufacturing difficulty.
3Reliability
If conducting terminals are suspended in the housing, then electrical connection is achieved, but internal space is occupied and device dimension increases
Solution Approach 1:
The conducting terminals are merged with the housing structure, eliminating the need for separate mounting features and support means. This integration allows the terminals to be positioned within the existing housing volume without requiring additional space, thereby minimizing the overall device dimension while maintaining reliable electrical connections.
