Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operation devices struggle to effectively remove noise generated from the device itself, such as operating sounds and mechanical sounds, which are not adequately addressed by current noise removal processes.
Innovation Solution
An operation device equipped with an interaction member, control circuit, and audio signal processing circuit, where the control circuit periodically acquires scan data on the interaction member's status and transmits it to the audio signal processing circuit to enhance noise removal accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a touch panel display device is made thinner and more integrated, then miniaturization and portability are improved, but the structure becomes more complex and harder to assemble
Solution Approach 1:
The patent combines the flexible printed circuit board and the touch sensor electrode into a single integrated structure. The circuit board serves dual functions as both the flexible substrate for electronics and the base layer for the touch sensor, eliminating the need for separate components and reducing overall device thickness while maintaining functionality.
Solution Approach 2:
The flexible printed circuit board is designed to perform multiple functions: it serves as the flexible substrate for mounting electronic components, as the conductive layer for touch sensing, and as the structural base for the entire touch panel assembly. This multi-functionality reduces the number of separate components needed.
2Volume of moving object
If touch panel components are integrated more closely, then miniaturization is improved, but disassembly for repair becomes more difficult
Solution Approach 1:
The patent segments the touch panel into distinct functional layers that are laminated together: the flexible printed circuit board layer, the touch sensor electrode layer, the protective layer, and the display panel. These segmented layers can be separated for repair or replacement while maintaining the integrated thin-form factor design.
Solution Approach 2:
The patent uses a laminated structure where multiple functional layers are nested together like dolls. Each layer can be independently accessed and removed by peeling apart the lamination, allowing repair of internal components while maintaining the compact nested structure during normal operation.
3Adaptability or versatility
If the circuit board is made flexible for curved surfaces, then adaptability is improved, but manufacturing precision becomes harder to control
Solution Approach 1:
The patent changes the physical parameter of the circuit board from rigid to flexible by using a flexible printed circuit board material. This allows the board to conform to curved surfaces while maintaining manufacturing precision through controlled lamination processes and precise electrode patterning on the flexible substrate.
Solution Approach 2:
The patent performs preliminary positioning and patterning of the circuit traces and electrode patterns on the flexible circuit board before final assembly. This preliminary action ensures that even though the board is flexible, the electrical connections and touch sensing elements are precisely positioned according to design specifications.

AI summary
Disclosed is an operation device including an interaction member, a microphone, a control circuit, and an audio signal processing circuit. The interaction member is used for interacting with a user. The control circuit periodically acquires scan data indicating the acting status of the interaction member. The audio signal processing circuit executes a noise removal process of removing noise from a collected audio signal collected by the microphone. The control circuit periodically transmits previously acquired scan data to the audio signal processing circuit. The audio signal processing circuit executes the noise removal process by using the scan data transmitted from the control circuit.
