Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices with press-type buttons face issues such as improper pressing, difficulty in driving the button point, button sticking, damage, and increased force requirement due to lack of support, leading to defects and functionality problems.
Innovation Solution
Incorporation of a button guiding element that restricts the motion of the second fixing element, ensuring proper alignment and support for the driving element to activate the circuit board's driving point, thereby reducing oblique positioning, sticking, and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If no button guiding element is provided, then the device structure is simpler, but the button will be deviated easily when pressed
Solution Approach 1:
A button guiding element is introduced as an intermediary component between the button and the device housing. This guiding element provides lateral support to the button during pressing, preventing deviation without requiring complex structural modifications to the button itself or the device housing.
Solution Approach 2:
The button assembly is segmented into distinct functional components: the button body, the fixing elements, and the separate guiding element. This segmentation allows the guiding element to be independently optimized for its specific function of preventing lateral deviation, while other components focus on their respective functions.
2Ease of operation
If the button is pressed without guidance, then the operation is more free, but the driving point can't be driven easily
Solution Approach 1:
The button guiding element acts as a mediator that channels the pressing force along the correct vertical path, ensuring the driving element effectively activates the driving point on the circuit board while maintaining operational freedom.
Solution Approach 2:
The guiding element is pre-installed in the device housing to establish the correct pressing path before the button is actuated. This preliminary positioning ensures that subsequent pressing actions automatically follow the correct trajectory to activate the driving point.
3Device complexity
If no button guiding element is provided, then the device structure is simpler, but the button will be stuck easily
Solution Approach 1:
The button guiding element serves as a mediator between the button and the housing, providing smooth lateral guidance that prevents the button from getting stuck during pressing or returning movements.
Solution Approach 2:
The guiding element creates a consistent guiding path with uniform clearance, ensuring the button experiences equal resistance in all lateral directions during operation, preventing sticking and ensuring smooth movement.
4Device complexity
If no button guiding element is provided, then the assembly is simpler, but the button will be damaged easily
Solution Approach 1:
The button guiding element acts as a protective intermediary that prevents lateral deviation and misalignment during button pressing, thereby reducing stress concentrations and preventing damage to the button and surrounding components.
Solution Approach 2:
The guiding element provides preemptive lateral support to the button, preventing excessive lateral forces that could cause damage before they occur during normal operation.
5Ease of operation
If the button is pressed obliquely without guidance, then the user has more flexibility, but a larger force shall be applied
Solution Approach 1:
The button guiding element mediates the pressing action by providing lateral constraints that guide the force application, allowing users to press with smaller force while maintaining flexibility in positioning.
Solution Approach 2:
The guiding element is pre-positioned to establish the correct pressing axis, allowing users to apply force more efficiently in the intended direction without requiring precise manual alignment, thereby reducing the overall force needed.

AI summary
A device with a button guiding element comprises a device substance, a button, a button guiding element, and a circuit board. The device substance has a button opening. The button comprises a button substance, a first fixing element, a second fixing element, and a driving element. The button substance is located in the button opening. The first fixing element is fixed to the first side of the button substance and engages with the device substance. The second fixing element is fixed to the second side of the button substance. The driving element is located on the button substance. The circuit board has a driving point, which is spaced apart from and in alignment with the driving element. The button guiding element disposed in the device substance is used to restrict the motion of the second fixing element to reduce the occurrence of a situation in which the button is obliquely positioned.
