Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional printed circuit board is used without special protective structures, then the device structure remains simple and manufacturing cost is low, but the circuit board and electronic components are vulnerable to damage from heat, inertial force, and external force
Solution Approach 1:
The patent applies preliminary action by providing an easily broken portion in the conductive portion before actual damage occurs to the circuit board or electronic components. This easily broken portion is designed to break first under stress, allowing the breakage detection mechanism to detect the stress condition before it propagates to critical components, thus preventing damage in advance
Solution Approach 2:
The easily broken portion serves as an intermediary element between the external stress and the critical circuit board/electronic components. It absorbs the stress by breaking first, acting as a sacrificial component that protects the more valuable parts of the system from damage
2Reliability
If manufacturing failures are not detected, then production time is reduced, but wiring failures and circuit board damage occur leading to erroneous operations and data loss
Solution Approach 1:
The breakage detection mechanism is integrated into the circuit board during manufacturing, allowing for automatic detection of wiring failures and conductive portion breakages. This preliminary detection capability identifies issues before they cause operational failures or data loss, enabling early intervention without significantly extending production time
Solution Approach 2:
The breakage detection mechanism provides continuous feedback about the condition of conductive portions through conduction tests. This feedback system allows real-time monitoring of the circuit board's health, enabling immediate detection of wiring failures and preventing erroneous operations by alerting the system to potential issues before they affect functionality

AI summary
According to one embodiment, a television apparatus includes a circuit board, a conductive portion, and an easily broken portion. The circuit board is mounted with an electronic component. The conductive portion is located on a surface or the inside of the circuit board. A breakage detection mechanism detects breakage of the conductive portion by conduction. The easily broken portion is provided to at least part of the conductive portion. The easily broken portion is broken easier than other portions of the conductive portion when a stress is applied to the circuit board.
