Solution Overview
Problem
The existing flat cable wiring structure in operation devices with vibration imparting mechanisms causes unstable vibratory feedback in touch panel devices due to tension, affecting the control of vibrating height.

A flat cable wiring structure with a routing portion that includes a bending portion and two intersecting routing portions, where the bending portion is movable and the second routing portion undergoes flexing deformation to absorb counterforces, reducing the impact of cable tension on vibratory feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flat cable is arranged in an S-shape within the body to connect the touch panel device and control board, then the electrical connection is established, but the tension of the flat cable causes the vibrating height of the touch panel device to become unstable
Solution Approach 1:
The flat cable routing is divided into multiple segments: a first routing portion extending from the touch sensor board downward, a bending portion with a bending portion, and a second routing portion extending along the control board. This segmentation allows each portion to perform its specific function - the first routing portion provides flexibility, the bending portion absorbs tension, and the second routing portion maintains stable electrical connection.
Solution Approach 2:
The flat cable routing is designed to be dynamically adaptable during vibration. The bending portion can change its curvature and the routing portions can flex to accommodate the vertical movement of the touch panel device during vibration, maintaining electrical connection while absorbing the dynamic forces generated during operation.
2Device complexity
If the flat cable is arranged vertically to connect the touch sensor board and control board, then the electrical connection is simplified, but the cable tension interferes with the vibratory feedback control
Solution Approach 1:
The bending portion acts as an intermediary element between the first routing portion and the second routing portion. It absorbs the tension forces generated during vibration and prevents these forces from being transmitted to the touch sensor board, thereby eliminating the harmful cable tension interference while maintaining the electrical connection.
Solution Approach 2:
The flat cable routing design converts the potentially harmful cable tension into a beneficial force by using the bending portion to absorb and dissipate the tension energy through flexing and deformation, preventing it from interfering with the vibratory feedback control while maintaining electrical connectivity.
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
This configuration ensures stable vibratory feedback control by reducing counterforces from the flat cable tension, maintaining consistent vibrating height without interference with the control board.
Implementation Method 1
the second routing portion is configured to undergo a flexing deformation so as to absorb a counter force to a stress transmitted from the operation mechanism to the second routing portion when vibration is imparted to the operation mechanism
Implementation Method 2
the routing portion comprises a bending portion (7a) that bends at a bending angle allowing the routing portion to be routed partially along the control board (6)

AI summary
A flat cable wiring structure includes an operation mechanism that detects a physical operation made on an operating surface and outputs a detection signal, a control board, disposed facing the operating surface of the operation mechanism, that outputs a driving signal for imparting vibration to the operation mechanism on the basis of the detection signal, and a flat cable that electrically connects the operation mechanism and the control board. The flat cable includes a routing portion that extends from the operation mechanism to the control board along a movement direction of the operation mechanism. The routing portion includes a bending portion that bends at a bending angle allowing the routing portion to be routed along the control board.
