Rotating Disc Handheld Controller for Large Screen Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen handheld electronic devices are difficult for users with smaller hands or those who need to operate them while lying down to hold and control securely, leading to instability and potential damage.
Innovation Solution
A handheld device with an annulus, first disc body, and second disc body, featuring contact points and probes that allow for rotational control of electronic equipment, enabling convenient one-handed operation and adjustment of volume or brightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the screen size of electronic equipment is increased, then the display area and visual effect are improved, but the device becomes difficult to hold and operate with one hand
Solution Approach 1:
The device is segmented into two functional parts: a larger electronic equipment body for display and a separate handheld device for control. The handheld device can be held independently while controlling the larger electronic equipment, allowing users to benefit from large screen area without the difficulty of holding a large device.
Solution Approach 2:
The handheld device acts as an intermediary between the user and the electronic equipment. It provides a stable holding structure and control interface, mediating the interaction between the user's hand and the larger electronic equipment, thereby solving the problem of difficult operation.
2Ease of operation
If a simple holding structure is added to electronic equipment, then ease of holding is improved, but the device functionality remains limited to holding only
Solution Approach 1:
The handheld device is designed with multi-functionality, serving both as a holding structure and as a control device. It can hold the electronic equipment stably while also providing control functions such as volume adjustment, brightness control, and other operations, thereby avoiding limitation to a single function.
3Device complexity
If the handheld device structure is simplified, then device complexity is reduced, but control precision and operation accuracy are affected
Solution Approach 1:
The handheld device incorporates a rotatable disc body with contact points that can rotate and make sequential contact with probes. This dynamic structure allows for precise control through rotational movement while maintaining relatively simple overall construction. The rotation mechanism provides accurate control input without requiring complex electronic components.

AI summary
The present invention provides a handheld device for controlling electronic equipment and an electronic equipment including the handheld device. The handheld device is electrically connected with a control unit of the electronic equipment. The handheld device includes an annulus, and a first and a second disc bodies arranged oppositely. A first contact point and at least three second contact points are arranged on the first disc body. A first probe and at least three second probes are arranged on the second disc body. The annulus is connected to the first disc body and is used for driving the first disc body to rotate. The second disc body is fixed to a shell of the electronic equipment.
