Adjustable Computer Mouse Top Part Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional computer mice with tiltable top parts are prone to damage or unintended angle changes when forcibly tilted, as existing locking mechanisms only allow for fixed angles and can break under excessive force.
Innovation Solution
A computer mouse design featuring an adjustable top part that can be tilted to any angle within a range, utilizing a locking device that applies a circularly symmetric radially directed force and an unlocking mechanism to prevent joint rotation, allowing the top part to shift without harm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed-angle locking mechanism with teeth is used to lock the top part, then the top part can be locked at selected angles, but the mouse may break or the teeth may wear down if excessive force is applied
Solution Approach 1:
The locking mechanism transitions from a discrete fixed-angle system to a continuous variable-angle system. The locking element can engage with the threaded joint at any position along the thread, allowing the top part to be locked at any angle within the threaded connection range, not just at predetermined discrete angles.
Solution Approach 2:
The locking mechanism is designed to be dynamically adjustable. The locking element can be engaged or disengaged from the threaded joint, allowing the system to transition between locked and unlocked states. When locked, it maintains the current angle; when unlocked, it allows repositioning to any new angle.
2Adaptability or versatility
If a releasing agent is used to unlock the fixed-angle locking mechanism, then the top part can be repositioned, but the mechanism requires additional components and complexity
Solution Approach 1:
The locking element serves dual functions: it acts as both the locking mechanism and the unlocking mechanism. By simply disengaging the locking element from the threaded joint, the user can reposition the top part to any angle. The same locking element then secures the new position, eliminating the need for separate releasing agents or additional unlocking components.
Solution Approach 2:
The locking element is designed to perform multiple functions within a single component. It provides both the locking function (securing the top part at a desired angle) and the unlocking function (allowing the top part to be repositioned). This multi-functionality simplifies the overall device structure by eliminating the need for separate unlocking mechanisms.
3Ease of operation
If the top part is made tiltable to any angle within a range, then ergonomic adjustment is improved, but the locking mechanism must prevent rotation while allowing repositioning
Solution Approach 1:
The system transitions from discrete angle locking to continuous angle adjustment. The threaded joint provides a continuous range of angular positions, and the locking element can engage at any position along this continuous range, allowing precise ergonomic adjustment to any desired angle within the threaded connection limits.
Solution Approach 2:
The locking mechanism is segmented into distinct functional components: the threaded joint that provides the continuous angular range, and the locking element that provides the stabilization function. This segmentation allows the system to simultaneously achieve both continuous adjustability and stable locking at the selected position.

Function Achieved in This Case
Enables ergonomic adjustment of the top part to any desired angle without damaging the joint, preventing unintended opening or closing and maintaining stability even when lifted.
Implementation Method 1

AI summary
The invention refers to a computer mouse with an adjustable top part (2). The lock can be tilted around a joint (15) to a chosen rotational position. The computer mouse is equipped with a locking device (12, 13a-b, 16) which locks the top part in the chosen position and the computer mouse is equipped with an unlocking device (13a-b) which enables the locking organ to be released from the locked position. The unlocking device (13a-b) may be a pushbutton (13a) or a handle (13b). In one design of the invention the top part is kept in position by a fastener equipped with teeth (4-5), where the locking device (12, 13a) locks the teeth in a position where they are meshed to each other. In an additional design of the invention the top part is kept in position by a locking device (13b, 16) which grabs the joint so that this cannot be tilted.
