Operation Panel Raising Mechanism for Flat-Surface Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with pivotable operation sections, such as operation panels, face limitations in flexibility of angle adjustment due to the need for a recessed portion for finger hooking, which can lead to design constraints and potential object entrapment issues.
Innovation Solution
An electronic device with an operation section that includes a storage section, an angle adjustment mechanism, a locking mechanism, and a raising mechanism, allowing the operation section to be adjusted to a desired angle without a recess for finger hooking, using a receiving member and contacting member to maintain the angle with minimal frictional force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a recessed portion for finger hooking is provided around the operation section, then the user can easily pivot the operation panel by hooking fingers, but the flexibility of operation when adjusting the angle is limited and small objects may fall into the recess portion
Solution Approach 1:
The patent removes the recessed portion for finger hooking from the housing surface and replaces it with a raising mechanism that actively lifts the operation section. This extraction eliminates the design constraint and potential object entrapment issue while maintaining ease of operation through automated raising assistance.
Solution Approach 2:
The patent introduces a raising mechanism as an intermediary between the user's pivoting action and the operation section. This mediator provides automated raising assistance, reducing the need for finger hooking recesses and enabling smoother angle adjustment without design constraints.
2Ease of operation
If the operation section is made pivotable for angle adjustment, then the user can view the operation section at comfortable angles, but the device requires additional mechanisms that increase complexity
Solution Approach 1:
The patent implements a dynamic angle adjustment mechanism where the operation section can be pivoted to various angles and held at each position through frictional contact between the contacting member and receiving member. This dynamic system provides viewing comfort at multiple angles without requiring complex locking mechanisms for each position.
Solution Approach 2:
The patent changes the friction parameter between the contacting member and receiving member to enable the operation section to be held at arbitrary angles. By controlling the frictional force, the system maintains the operation section at different angular positions without additional mechanical complexity.
3Reliability
If a locking mechanism is added to lock the operation section in the storage section, then the operation section is securely held in position, but the mechanism requires additional components that increase device complexity
Solution Approach 1:
The locking mechanism is designed to automatically engage when the operation section is in the storage position. The contacting member and receiving member self-lock through frictional contact without requiring additional actuators or complex control systems, achieving reliable storage while minimizing complexity.

AI summary
The printing device includes an operation section 15, an angle adjustment mechanism 60, a locking mechanism 70, and a raising mechanism 80. The locking mechanism 70 switches from the locked state to the unlocked state when a specific operation is performed on the operation section 15 in the locked state. The angle adjustment mechanism 60 is provided with the receiving member 63 provided in the operation section 15, and a contacting member 64 for holding the operation section 15 at an arbitrary angle by the raising mechanism 80 of the operation section 15. The receiving member 63 is provided with a portion where the contacting force of the contacting member 64 to the receiving member 63 becomes smaller than the predetermined force in the process that the operation section 15 is raised by the prescribed angle.
