Grip-Mounted Operation Unit for Handheld Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld display apparatuses require users to temporarily stop using the device and release their grip to provide control instructions, such as powering on/off or adjusting display settings, which impairs usability and can lead to erroneous operations due to frequent hand release and re-gripping.
Innovation Solution
A handheld display apparatus with a grip portion featuring bar members and an operation unit that allows users to perform control operations, such as powering on/off or adjusting settings, without releasing their grip, through mechanisms like mechanical or wireless signal transmission, enabling hands-free control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation unit is arranged separately from the grip portion, then the display unit can be controlled, but the user must release the grip to operate controls which reduces usability
Solution Approach 1:
The operation unit is integrated into the grip portion, merging the control function with the gripping function. This allows users to operate controls while maintaining their grip on the device, eliminating the need to release and re-grip the device for each operation.
2Ease of operation
If the operation unit is integrated into the grip portion, then hands-free control is enabled, but the grip structure becomes more complex
Solution Approach 1:
The grip portion is designed to serve multiple functions: it provides the mechanical grip structure for holding the device and simultaneously houses the operation unit for control inputs. This multi-functionality reduces the need for separate components and minimizes overall structural complexity.
3Adaptability or versatility
If frequent hand release and re-gripping is required for control operations, then control functions can be accessed, but erroneous operations increase and usability deteriorates
Solution Approach 1:
The design enables continuous control operation while maintaining the gripping action. Users can press buttons or operate controls without releasing their grip, ensuring the useful action of holding and controlling the device continues uninterrupted, thereby preventing erroneous operations caused by hand release and re-gripping.
