Camera Fixing Bracket with Limited Foot Unfolding Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fixing brackets for photographing devices often experience excessive sliding of support feet, leading to reverse folding or damage due to large unfolding angles, which compromises their supporting function.
Innovation Solution
A fixing bracket design featuring a rod member with limiting protrusions near the bottom end to prevent the sliding member and supporting feet from sliding further, ensuring a fixed unfolding angle by interfering with the sliding member when it reaches the protrusions, thus maintaining a stable supporting function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hinge member is disposed closer to the bottom end of the rod member to increase the unfolding angle of the support feet, then the supporting function is improved, but the support feet may excessively slide and reverse fold causing damage
Solution Approach 1:
The patent applies preliminary anti-action by introducing a limiting structure (limiting protrusion on the rod member abutting against a limiting surface on the sliding member) that prevents the support feet from unfolding beyond a predetermined angle. This counteracts the tendency of the support feet to excessively slide and reverse fold, thereby protecting the supporting feet from damage while maintaining adequate supporting function.
2Ease of operation
If no limiting structure is provided to allow free sliding of the support feet, then the ease of operation is improved, but the support feet may reverse fold and lose supporting function
Solution Approach 1:
The limiting structure is designed to remain inactive during normal operation, allowing the support feet to slide freely for unfolding. However, when the support feet reach the predetermined unfolding angle, the limiting protrusion abuts against the limiting surface to prevent further sliding, thus maintaining the stability of the supporting function while preserving ease of operation within the safe range.

AI summary
A fixing bracket for a photographing device includes a rod member, a sliding member, and a plurality of supporting feet. The sliding member is slidably sleeved on an outer surface of the rod member, top ends of the plurality of supporting feet are hinged to the sliding member, and the supporting feet are swingable with respect to the sliding member, at least one limiting protrusion is disposed on the outer surface of the rod member close to a bottom end of the rod member, the at least one limiting protrusion is configured to block the sliding member or the supporting feet from sliding towards the bottom end of the rod member, the at least one limiting protrusion is disposed between the sliding member and the bottom end of the rod member. When the sliding member slides towards the bottom end of the rod member, the supporting feet are gradually unfolded.
