Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the transmitter and charger are reused multiple times, then cost reduction and environmental protection are achieved, but moisture and rust cause damage and reduce service life

Engineering Contradiction:

Improveservice lifeVSAvoidmoisture damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies the inert atmosphere principle by creating a moisture-proof environment using a cover that seals the accommodating space and desiccant that absorbs moisture. This protects the transmitter and charger from moisture damage during storage and charging, enabling reliable repeated use without rust or corrosion.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

Solution Approach 2:

The patent uses desiccant as an intermediary substance that actively absorbs moisture within the accommodating space. This intermediary element mediates between the external humid environment and the internal components, preventing moisture from reaching and damaging the transmitter and charger.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the transmitter is disassembled from the patch base for charging, then reusability is enabled, but improper connection may cause damage

Engineering Contradiction:

ImprovereusabilityVSAvoidconnection safety

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies asymmetry by designing the electrical connection structure with directional features - the cover can only be closed in one correct orientation, ensuring the electrical contacts align properly. This prevents improper connection and damage while enabling safe repeated charging cycles.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The patent implements preliminary action by pre-positioning the electrical connection structures in predetermined orientations before use. The asymmetric design ensures that when the cover is closed, the connection is automatically correct, eliminating the need for user judgment and preventing connection errors during repeated charging operations.

Inventive Principle:

Principle #10Preliminary action

AI summary

A moisture-proof assembly for keeping away from a moisture comprises a housing, a cover, a physiological signal transmitter, a charging device and a desiccant. The housing has an opening. The cover is detachably disposed on the housing, configured to seal the opening, and forms an accommodating space together with the housing. The physiological signal transmitter is disposed in the accommodating space for measuring and transmitting a physiological signal. The charging device is combined with the physiological signal transmitter and disposed together or the charging device and the physiological signal sensor are separate disposed in the accommodating space. The desiccant is disposed in the accommodating space to prevent the physiological signal transmitter from moisture, wherein when the physiological signal transmitter is in need of being charged, the charging device is taken out of the accommodating space, and connected to an external power source to charge the physiological signal transmitter.
