Resizable Wireless Pointing Device With Storable Receiver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless pointing devices with storable receivers lack versatility, as their storage compartments are solely dedicated and do not allow for size adjustment to accommodate different hand sizes or operational needs.
Innovation Solution
A resizable wireless pointing device with a storable receiver, featuring a sliding cover that alters the device's size by sliding along the longitude axis of the body housing, and a shutter that seamlessly closes the gap area, enabling storage of the receiver and accommodating various hand sizes and operational spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a storage compartment is added to store the wireless receiver, then the device can store the receiver, but the device size becomes fixed and cannot accommodate different hand sizes
Solution Approach 1:
The patent applies the dynamics principle by making the device size adjustable through a sliding cover mechanism. The cover can slide along guide rails to change the exposed length of the device body, allowing the same device to adapt to different hand sizes and user preferences. This dynamic adjustment capability resolves the contradiction between fixed structure and size adaptability.
Solution Approach 2:
The storage compartment serves multiple functions: it stores the wireless receiver when not in use, and simultaneously acts as part of the device body structure. The compartment is integrated into the housing rather than being a separate add-on, making the device more versatile without proportionally increasing complexity.
2Adaptability or versatility
If the device size is made adjustable to accommodate different hand sizes, then size adaptability is improved, but the structural complexity increases
Solution Approach 1:
The device is segmented into a fixed base body and a movable sliding cover portion. This segmentation allows the device to be divided into functional zones: the stationary housing containing electronic components and the adjustable cover providing size customization. The segmentation simplifies the adjustment mechanism compared to redesigning the entire device structure.
Solution Approach 2:
Guide rails serve as an intermediary mechanism between the sliding cover and the base body. These rails provide a simple yet effective way to constrain the cover's movement to a linear path, enabling smooth size adjustment without complex mechanical linkages or motorized systems.
3Ease of operation
If a sliding cover is added to alter device size, then size adjustment capability is improved, but the device structure becomes more complex
Solution Approach 1:
The sliding cover mechanism is designed to be manually operated by the user without requiring tools or complex activation sequences. The cover slides freely along the guide rails when pushed or pulled, allowing users to adjust the device size intuitively based on their hand size preferences. This self-service design maximizes ease of operation while minimizing mechanical complexity.

AI summary
The present invention relates to a resizable wireless pointing device with a storable receiver. The body housing comprises at least one inner compartment which is located next to the back of a wheel and used for storage of the wireless receiver. A sliding cover, located on the top of the body housing, which slides back and forth along the longitude axis of the housing and subsequently alters the size of the wireless pointing device. A shutter, which rolls up following the sliding of the cover, closes seamlessly the gap area between the body housing and the cover, and integrates into the surface of the wireless pointing device.
