Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long-term use of standard pointing devices can lead to user discomfort due to inadequate ergonomic fit, causing hand cramping and other issues for users such as game enthusiasts.
Innovation Solution
An adjustable pointing device with a telescopic column and gear assembly that allows users to modify the separation distance between the grip and base, featuring a locking mechanism and elastic member for customizable fit, along with a hinge for adjusting the grip's inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard fixed geometry pointing device is used, then the device structure is simple and easy to manufacture, but it causes user discomfort and hand cramping during long-term use due to inadequate ergonomic fit
Solution Approach 1:
The pointing device incorporates an adjustable column that can change its length to modify the separation distance between the grip portion and base. This dynamic adjustment allows the device geometry to adapt to different user hand sizes and preferences, resolving the contradiction between fixed simple structure and customizable ergonomic fit.
Solution Approach 2:
The device enables parameter changes by allowing users to adjust the column length to different positions (e.g., first position, second position). This changes the separation distance parameter, thereby modifying the overall device geometry to achieve better ergonomic fit without completely redesigning the structure.
2Adaptability or versatility
If an adjustable column is added to modify separation distance, then user comfort is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The column is divided into multiple segments or sections that can be adjusted relative to each other. This segmentation allows for length adjustment while keeping each individual segment simpler to manufacture, and the assembly process becomes a matter of connecting standardized components rather than creating a completely custom adjustable mechanism.
3Reliability
If a locking assembly with gear mechanism is implemented, then the column position can be securely locked, but the device complexity increases
Solution Approach 1:
The locking assembly is designed to be actuated by the user through a simple switching operation, and the gear mechanism automatically engages or disengages to lock or unlock the column position. This self-service mechanism eliminates the need for complex external locking systems or multiple components, achieving reliable position locking through a user-friendly single operation.

AI summary
An adjustable pointing device is disclosed wherein the device comprises a base, a grip portion, and an adjusting mechanism, the grip portion being attached to the base by the adjusting mechanism wherein the adjusting mechanism comprises an elastic member biasing the grip portion away from the base and comprising a locking mechanism movable between a locked position in which the locking mechanism is to prevent the grip portion from moving relative to the base and an unlocked position in which the locking mechanism is to allow the grip portion to move relative to the base.
