Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional holder design is used, then the assembly process is simple, but the circuit board cannot be securely fastened and may detach under external impact
Solution Approach 1:
The holder is divided into multiple functional segments: a body portion for mounting, a protrusion for positioning, and a clip mechanism for securing. This segmentation allows each part to perform its specific function efficiently while maintaining overall structural integrity and preventing circuit board detachment
Solution Approach 2:
The clip is nested within the holder body, with the clip's engagement portion fitting into a corresponding groove on the circuit board. This nested configuration allows the securing mechanism to be integrated into the holder structure without significantly increasing external dimensions or assembly complexity
2Reliability
If a secure fastening mechanism is added to the holder, then the circuit board is prevented from detaching, but the assembly convenience is reduced
Solution Approach 1:
The protrusion is pre-formed on the holder body, and the clip is pre-positioned in its engagement state. During assembly, the circuit board is simply inserted onto the protrusion and secured by the pre-configured clip, eliminating the need for separate fastening operations and maintaining assembly convenience while ensuring secure attachment

AI summary
A display device is disclosed. The display device includes a display panel, a frame behind the display panel, a circuit board (110PC) at a rear of the frame, a flexible printed circuit board (MB) connecting the display panel and the circuit board, and a holder (400) coupled with the rear of the frame. The holder comprises a clip (404) configured to receive the circuit board to secure the circuit board (110PC) to the holder, the clip comprising a palm (404c), a first finger (404a), and a second finger (404b), wherein the first finger and the second finger are extended from both ends of the palm (404c), a plurality of hooks (406, 408) configured to secure the holder to a surface of the frame, and a body (402) forming the palm (404c) of the clip as an angled supporting surface to support the circuit board at an angle with respect to the surface of the frame.
