Dismountable hand grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dismountable hand grips require both hands to assemble and disassemble, are prone to wobbling due to single connection points, and have an aesthetically unappealing design with extended control rods.
Innovation Solution
A dismountable hand grip featuring two locking pieces with elastic components and pins, allowing single-handed operation through a connection chamber with guiding slots and reinforcing plates for enhanced stability, and additional fastening units to prevent wobbling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single control rod and single locking piece structure is used, then the device complexity is reduced, but the ease of operation deteriorates because both hands are required for assembly and disassembly
Solution Approach 1:
The locking mechanism is segmented into two symmetric locking pieces instead of a single control rod. Each locking piece is independently controlled, allowing one hand to operate both pieces simultaneously. This segmentation enables single-handed operation while maintaining structural simplicity through symmetry.
2Device complexity
If a single connection point is used between the hand grip and body, then the device complexity is reduced, but the stability deteriorates causing wobbling during usage
Solution Approach 1:
The single connection point is segmented into two connection points through the use of two locking pieces positioned at different locations on the hand grip. This distributes the connection load and prevents wobbling while maintaining a relatively simple overall structure.
3Ease of operation
If the control rod is extended outside the grip, then the ease of operation is improved for single-handed control, but the volume increases and aesthetic appeal deteriorates
Solution Approach 1:
The locking pieces are nested inside the hand grip body rather than extending outward. The two fingers press on the outer surface of the grip to actuate the internal locking pieces, which rotate within the grip's internal cavity. This nesting approach maintains compact volume while enabling single-handed operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick, single-handed assembly and disassembly, maintains a compact design, and significantly improves stability and aesthetic appeal by distributing the locking mechanism within the hand grip.
Implementation Method 1
a back part of each of the locking pieces is a compression unit which is connected with the hand grip through the elastic component
