Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fingerprint recognition area is increased by adding optical fingerprint recognition devices, then fingerprint recognition performance and security performance are improved, but mounting space in the electronic device becomes difficult to secure
Solution Approach 1:
The patent combines the optical fingerprint recognition device with the speaker enclosure by positioning the fingerprint recognition area within the speaker enclosure structure. This merging allows the speaker enclosure to serve dual purposes: housing the speaker and providing mounting space for the optical fingerprint recognition device, thereby increasing fingerprint recognition area without requiring additional separate mounting space.
Solution Approach 2:
The speaker enclosure is designed to perform multiple functions: it houses the speaker for audio output and simultaneously provides a mounting structure for the optical fingerprint recognition device. This multi-functionality resolves the space constraint by making the speaker enclosure serve both acoustic and biometric authentication purposes.
2Reliability
If multiple optical fingerprint recognition devices are disposed to increase recognition area, then security performance is improved, but device complexity increases
Solution Approach 1:
Multiple optical fingerprint recognition devices are integrated within the speaker enclosure structure, merging their mounting requirements into a single structural framework. This consolidation reduces the overall complexity compared to having separate mounting structures for each device, as the speaker enclosure serves as a common mounting platform for all fingerprint recognition devices.
