Solution Overview
Problem
Existing auxiliary mirror fastening devices have complex structures with numerous components, leading to increased manufacturing costs and assembly difficulties, and require specific materials for sloping teeth, limiting flexibility.
Innovation Solution
The auxiliary mirror fastening device incorporates a positioning unit with first and second operation members, fastening straps, and a simplified design that allows for easy assembly and adjustable tension, using resilient and rigid materials for the fastening seat and mounting seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a binding unit with multiple components (seat body, engaging member, cover body, operation member, elastic members) is used to secure the fastening strap, then the fastening reliability is improved, but the device complexity increases and assembly becomes complicated
Solution Approach 1:
The patent merges the seat body, engaging member, and operation member into a single integrated mounting seat structure. The mounting seat includes a body portion with an engaging groove that directly receives the fastening strap, eliminating the need for separate engaging members and cover bodies. This consolidation maintains fastening reliability while significantly reducing device complexity and assembly steps.
Solution Approach 2:
The patent extracts and eliminates unnecessary components from the binding unit. By removing the cover body and separate engaging member, the design achieves the same fastening function with fewer parts. The operation member is simplified to a lever that directly acts on the engaging groove, removing the complexity of multiple interconnected components while maintaining operational reliability.
2Reliability
If sloping teeth are formed on the fastening strap to engage with the binding unit, then the fastening mechanism can grasp and release the strap, but the strap is limited to specific materials and manufacturing costs increase
Solution Approach 1:
Instead of forming sloping teeth on the flexible fastening strap, the patent inverts the design by providing the engaging groove and teeth structure on the rigid mounting seat. The fastening strap becomes a simple continuous belt without complex tooth formations. This inversion allows the strap to be manufactured from various materials including rubber, silicone, or thermoplastic elastomers using standard molding processes, significantly reducing manufacturing costs while maintaining the grasping and releasing function through the mounting seat's toothed engaging groove.
3Ease of operation
If multiple operation members with multiple components are used to control the fastening straps, then the adjustable tension function is improved, but the device complexity and assembly difficulty increase
Solution Approach 1:
The patent merges the positioning unit and operation members into a simplified mounting seat structure. The mounting seat includes a body portion with an engaging groove that provides both positioning and tension adjustment functions through a single integrated component. This consolidation maintains the adjustable tension capability while eliminating the complexity of multiple separate operation members and their interconnecting mechanisms.
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
The simplified structure facilitates easy assembly and adjustable tension, reducing manufacturing costs and enhancing flexibility in fitting various side-view mirrors, while maintaining secure attachment of auxiliary mirrors.
Implementation Method 1
the second fastening strap is pulled by the pulling portion and clamped by the first press surface and the abutting portion
Implementation Method 2
The fastening seat is made from a resilient material, such as a thermoplastic elastomer or a thermoplastic rubber, so that the fastening seat provides a restoring force when compressed
Implementation Method 3
The first pivot portion is rotatably connected to the first shaft... The second pivot portion is rotatably connected to the second shaft
Implementation Method 4
The first lever portion is disposed at one side of the pulling portion... The second lever portion interconnects the second pivot portion and the sliding portion

AI summary
An auxiliary mirror fastening device has a first fastening strap, a second fastening strap, an abutting portion, a first operation member that has a first press surface, and a second operation member that has a second press surface. The second fastening strap is pullable through between the first press surface and the abutting portion when the first operation member is in a first state, and is clamped by the first press surface and the abutting portion when the first operation member is moved from the first state to a second state. When the second operation member is in an unoperated initial state, the second press surface clamps the second fastening strap against the abutting portion.
