Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors for coordinate input devices suffer from incomplete contacting, excessive cable length, weak signal transmission, and frequent loosening or breaking of flat cables, leading to instability and lack of compactness.
Innovation Solution
A three-dimensional connector design featuring a flat conductor cable with perpendicularly penetrating conductive lines or a naked-copper connector that shortens the cable length and secures it firmly, using a vertical guiding pin or soldered conductive contact head to enhance signal transmission and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flat cable with optional length is connected to connectors of control card, then the connection is simple and convenient, but the cable becomes excessive long and loose, leading to incomplete contacting and weak signal
Solution Approach 1:
The patent transitions from a conventional planar cable connection to a three-dimensional perpendicular connection. The flat cable is routed perpendicularly through a slot in the support plate to connect the touch pad to the control card, creating a vertical signal transmission path that reduces cable length and eliminates excess cable loose in the horizontal plane.
2Adaptability or versatility
If a flat cable with optional length is used, then the cable can reach the control card, but the cable loosens and breaks easily
Solution Approach 1:
The cable is routed perpendicular to the support plate through a vertically oriented slot, changing the cable's spatial arrangement from horizontal to vertical. This perpendicular routing through the slot provides mechanical support and constraint, preventing cable loosening and breaking while maintaining reachability between components.
Solution Approach 2:
The slot in the support plate acts as an intermediary structure that guides and secures the flat cable. The slot provides a defined pathway that constrains the cable's movement and position, enhancing cable stability and preventing loosening while allowing the cable to maintain its connection between the touch pad and control card.
3Ease of manufacture
If conventional connectors are used, then the assembly is straightforward, but the connection is incomplete and signal is weak
Solution Approach 1:
The signal transmission path is changed from a horizontal planar connection to a vertical three-dimensional connection through the support plate. The flat cable passes perpendicularly through the slot to establish direct contact between the touch pad and control card, improving signal strength and connection completeness while maintaining manufacturing simplicity.
