Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmitter is made reusable with a rechargeable battery, then cost reduction and environmental protection are achieved, but the device becomes vulnerable to moisture damage reducing its service life
Solution Approach 1:
The patent applies the inert atmosphere principle by creating a moisture-proof environment through a cover assembly that seals the transmitter and charger. This protective enclosure isolates the electronic components from harmful moisture in the external environment, effectively creating a controlled inert atmosphere that prevents rust and damage, thereby extending the service life of the reusable transmitter.
2Ease of operation
If the charging connector is made movable to accommodate angled electrical connection, then charging functionality is improved, but the device becomes susceptible to improper impact and damage
Solution Approach 1:
The patent applies beforehand cushioning by incorporating a buffer assembly that includes a buffer member positioned between the charging connector and the external environment. This buffer member absorbs and mitigates improper impacts or forces applied to the connector during charging operations, protecting the connector from damage while allowing the necessary movement for proper alignment and electrical connection.
3Volume of moving object
If the transmitter is miniaturized for long-term wear, then user comfort and functionality are improved, but moisture protection becomes more challenging
Solution Approach 1:
The patent applies the nested doll principle by placing the miniaturized transmitter inside a protective cover assembly that seals it from moisture. The charger is also nested within the same protective environment. This nested structure allows the small transmitter to maintain its compact size for user comfort while the outer cover provides comprehensive moisture protection, solving the contradiction between miniaturization and protection.
4Reliability
If the charging device includes positioning and safety mechanisms, then charging reliability is improved, but the device complexity increases
Solution Approach 1:
The patent applies merging by combining multiple functions into integrated assemblies. The cover assembly serves both as a moisture-proof enclosure and as a structural framework. The buffer assembly integrates positioning, impact protection, and connector guidance functions. This merging approach achieves reliable charging with positioning and safety mechanisms while minimizing overall structural complexity through functional integration.

AI summary
A moisture-proof assembly (2) for keeping away from a moisture, comprises a housing (20), a cover (24), a physiological signal transmitter (7) and a desiccant (29). The housing (20) has an opening (23'). The cover (24) is detachably disposed on the housing (20), configured to seal the opening (23'), and forms an accommodating space (20') together with the housing (20). The physiological signal transmitter (7) is disposed in the accommodating space (20') for measuring and transmits a physiological signal. The desiccant (29) is disposed in the accommodating space (20') to prevent the physiological signal transmitter (7) from moisture, characterized in that: the physiological signal transmitter (7) is configured to be taken out from the accommodating space (20'), so that the physiological signal transmitter (7) can be assembled to a sensor pedestal (80) for measuring the physiological signal.
