Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless charging receiver is designed on the backplate of handheld device, then wireless charging function is achieved, but manufacturing cost increases and device complexity increases due to design modifications and extra terminals

Engineering Contradiction:
Improvewireless charging functionVSAvoiddevice design modification
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wireless charging receiver is separated from the handheld device and integrated into the battery pack instead. This segmentation allows the battery pack to independently provide wireless charging capability without requiring modifications to the handheld device structure, terminals, or circuitry.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The battery pack is designed to serve multiple functions: it acts as both the power source for the handheld device and the wireless charging receiver. By integrating the wireless charging receiver into the battery pack, a single component (battery pack) performs both energy storage and wireless power reception functions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If wireless charging receiver is designed as cover of handheld device, then wireless charging function is achieved, but wired charging interface is occupied causing user complexity

Engineering Contradiction:
Improvewireless charging functionVSAvoidcharging interface availability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The wireless charging receiver is segmented away from the handheld device body and placed in the battery pack. This physical separation ensures that the wired charging interface of the handheld device remains accessible and unaffected, as the wireless charging function is now provided by the battery pack itself rather than through a cover that would block the interface.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If wireless charging receiver is integrated into handheld device, then wireless charging function is achieved, but manufacturing cost increases

Engineering Contradiction:
Improvewireless charging functionVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The wireless charging receiver is merged with the battery pack, which is a separate component from the handheld device. This combining approach allows the wireless charging functionality to be added to an existing component (battery pack) that is already part of the device assembly, avoiding the need for additional manufacturing steps or cost increases for the handheld device itself.

Inventive Principle:
Principle #5Merging (Combining)
