Wrench Display Bracket Ratchet Mount for Angle Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display brackets for wrenches are complex, costly to produce, and lack durability due to their multi-part structures, which complicate the recognition of rotational angles and increase production costs.
Innovation Solution
A simplified display bracket design comprising a main body with a through locking hole and symmetric parallel slots, and a mount with a cylindrical connecting member and ratchet, allowing for angular displacement recognition through a repetitious jump feeling and sounds produced by the interaction between the ratchet and flexible piece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a multi-part structure (hanger post, flexible plate, nut with teeth) is used to produce angular displacement recognition, then the rotational angle can be recognized through jump feeling and sounds, but the structure becomes too complicated and production cost increases
Solution Approach 1:
The patent combines multiple components (hanger post, flexible plate, and nut with teeth) into a single integrated mount structure. The mount directly incorporates the flexible piece and ratchet teeth, eliminating the need for separate hanger post and nut components. This merging maintains the angular displacement recognition function through the interaction between the ratchet teeth and flexible piece, while significantly simplifying the overall structure and reducing production cost.
Solution Approach 2:
The patent extracts and eliminates unnecessary components from the conventional multi-part structure. By removing the separate hanger post and retaining only the essential mount with integrated flexible piece and ratchet mechanism, the design achieves angular displacement recognition with a simpler structure that is more cost-effective to produce.
2Measurement precision
If a flexible part is used to provide resistant torque for rotational angle recognition, then the rotational angle can be recognized, but the flexible part is not durable and resistant torque disappears after fatigue
Solution Approach 1:
The patent modifies the parameters and material properties of the flexible piece to enhance its durability. By optimizing the flexibility, thickness, and material composition of the flexible piece, the design maintains the necessary resistant torque for rotational angle recognition while improving resistance to fatigue and extending service life.
3Measurement precision
If conventional display brackets with multiple components are used, then angular displacement can be recognized, but exhibition space is not economized and production cost increases
Solution Approach 1:
The patent merges multiple separate components into a single integrated mount structure that combines the hanger post, flexible piece, and ratchet mechanism. This consolidation reduces the number of parts that need to be manufactured, assembled, and displayed, thereby economizing exhibition space and reducing production costs while maintaining the angular displacement recognition function.

Function Achieved in This Case
The solution provides a cost-effective, durable, and easy-to-produce display bracket that accurately recognizes angular displacement with a simpler structure, reducing production costs and enhancing user feedback through auditory cues.
Implementation Method 1
The interaction between an annular ratchet and a flexible piece on a dial on the main body produces a repetitious jump feeling and sounds
Implementation Method 2
A flexible piece is formed between the symmetric slots

AI summary
A display bracket for a wrench that achieves the purpose of economizing exhibition space comprises a locking hole capable receiving a cylindrical connecting member of a mount of and a main body further consisting of a flexible piece near the locking hole, whereby the main body will connected to the mount by a plurality of arced projection around the connecting member. The connecting member can further secured with the maim body by the engagement between a ratchet on the outer rim thereon and the flexible piece. Thereby, the wrench can be hung on the display bracket for exhibition.
