Flexible Wiring Protection for Moving Display Ring Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display apparatuses with a ring member that moves relative to the display screen, such as liquid crystal displays, the electrical wiring connecting LED lights to a driver circuit is prone to breakage due to excessive tension from the movement, necessitating protection to prevent disconnection and damage.
Innovation Solution
The electrical wiring is arranged between a base member and a ring member with a connecting board, featuring a turning portion and a space adjusting piece to maintain a predetermined space, and a fixing piece to secure the wiring ends, preventing disconnection and damage during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ring member moves relative to the display screen to create dynamic visual effects, then the entertainment value and visual appeal are improved, but the electrical wiring is subjected to excessive tension and may break
Solution Approach 1:
The electrical wiring is divided into multiple segments: a first wiring connected to the ring member, a connecting board fixed to the display screen, and a second wiring connected to the driver circuit. This segmentation allows the first wiring to move with the ring member while the second wiring remains relatively stationary, reducing tension and preventing breakage during dynamic visual effects.
Solution Approach 2:
A connecting board is introduced as an intermediary component between the moving ring member and the stationary driver circuit. The connecting board serves as a fixed connection point that mediates the relationship between the moving and stationary wiring portions, allowing the ring member to move freely while maintaining reliable electrical connections.
2Adaptability or versatility
If flexible wiring material is used to accommodate the movement of the ring member, then the adaptability to movement is improved, but the wiring becomes vulnerable to breaking from excessive tension
Solution Approach 1:
The wiring system is segmented into a first wiring portion that flexes with the ring member's movement and a second wiring portion that remains more stationary. This segmentation allows each portion to be optimized for its specific function: the first wiring accommodates movement while the second wiring maintains strength and stability.
Solution Approach 2:
The connecting board acts as an intermediary that anchors the wiring system at a fixed point. This intermediary structure allows the flexible first wiring to move with the ring member while the second wiring connected to the driver circuit remains stable and less susceptible to tension-induced breakage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively protects the electrical wiring from breakage and disconnection by maintaining a suitable space and securing the wiring ends, ensuring continuous power supply and preventing the scattering of deteriorated medium substances.
Implementation Method 1
a space adjusting piece is provided on the moving member to maintain a predetermined space between a base member portion of the second wiring and a moving member portion of the second wiring, which are separated at the turning portion
Implementation Method 2
a fixing piece is formed integrally with the space adjusting piece to fix the end portion of the wiring to the connecting board by elastically pushing the end portion
