Battery Fan Clamping Assembly for Wider Jaw Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power tools, such as fans, have limited usage scenarios due to a small maximum opening distance between the clamping jaws, resulting in poor clamping stability and limited applicability.
Innovation Solution
A fan design featuring a clamping assembly with a first jaw closer to the fan blades, a second jaw farther away, and an adjustment member that increases or decreases the opening distance between the jaws, allowing for a maximum opening distance of at least 35 mm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the maximum opening distance between the first jaw and the second jaw is increased to at least 35 mm, then the adaptability and versatility of the fan are improved, but the device complexity increases due to the adjustment member mechanism
Solution Approach 1:
The clamping assembly incorporates an adjustment member that enables dynamic modification of the opening distance between the first jaw and second jaw. This dynamic mechanism allows the fan to adapt to various clamping scenarios by adjusting the jaw separation to at least 35 mm, resolving the contradiction between fixed structural simplicity and adaptive versatility.
Solution Approach 2:
The adjustment member modifies the geometric parameter of the opening distance between the jaws. By changing this parameter to a maximum of at least 35 mm, the system achieves improved adaptability for different external fixed components while managing the inherent complexity through a dedicated adjustment mechanism.
2Stability of the object's composition
If the first jaw is positioned closer to the outer edges of the fan blades than the second jaw, then the clamping stability is improved, but the symmetry and simplicity of the clamping assembly structure is reduced
Solution Approach 1:
The clamping assembly deliberately employs asymmetric positioning where the first jaw is located closer to the outer edges of the fan blades than the second jaw. This asymmetric configuration optimizes clamping stability by better distributing forces during operation, accepting the trade-off of increased structural complexity over symmetric simplicity.

AI summary
A fan includes: a support base; a fan assembly; a battery pack coupling portion located at an end of the fan adjacent to the support base and used for mounting a battery pack powering the fan assembly; and a clamping assembly disposed on the support base and used for clamping the support base to an external fixed component. The clamping assembly includes a first jaw, a second jaw, and an adjustment member. The adjustment member passes through the first jaw and the second jaw. The adjustment member is operated to increase or decrease an opening distance between the first jaw and the second jaw. The maximum opening distance formed between the first jaw and the second jaw is greater than or equal to 35 mm.
