Shock-absorbing Tie Brace with Segmented Resilient Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shock-absorbing tie braces are difficult and costly to assemble, with the central member prone to bending and deformation during welding, leading to reduced structural strength.
Innovation Solution
A shock-absorbing tie brace design featuring two primary containment members and a central member with a resilient body and lateral containment members, where the resilient body has nonlinear edges that correspond to the lateral containment members, allowing for easy assembly and enhanced structural strength through sliding and reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the central member is welded together from three steel plates, then structural strength is improved, but the central member is easily bent or deformed during welding and requires subsequent straightening
Solution Approach 1:
The central member is divided into three separate steel plates (first, second, and third plates) that are positioned at specific angles to each other, allowing each plate to be manufactured and assembled independently rather than welding a complex X-shaped structure as a single unit
Solution Approach 2:
The three separate steel plates are combined using connecting plates and fasteners to form the central member structure, merging multiple simple components into a functionally equivalent but easier-to-manufacture assembly
2Strength
If the central member is welded together, then structural strength is improved, but the straightening process damages the central member and reduces structural strength
Solution Approach 1:
By segmenting the central member into three separate plates that are assembled together, the design eliminates the need for post-welding straightening operations, thereby preventing damage and maintaining structural integrity
Solution Approach 2:
The steel plates are positioned and secured in their correct orientations before final assembly, preventing deformation issues from developing in the first place rather than requiring corrective straightening afterward
3Strength
If multiple connecting plates are used to connect side members, then structural strength to prevent buckling is improved, but assembly difficulty and time increase
Solution Approach 1:
Multiple connecting plates are merged into a single integrated connecting plate structure that performs the same function of connecting side members and preventing buckling, thereby reducing the number of separate components and simplifying assembly
Solution Approach 2:
The connecting plate is designed to simultaneously perform multiple functions: connecting side members to the central member, providing buckling resistance, and maintaining structural alignment, eliminating the need for separate dedicated components for each function
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 design simplifies manufacturing, reduces deformation risks, and enhances structural strength by allowing the resilient body to absorb shocks without buckling, while maintaining ease of assembly and cost-effectiveness.
Implementation Method 1
Each central member has a top, a bottom, a resilient body and two lateral containment members. The resilient body has two nonlinear edges.

AI summary
A shock-absorbing tie brace has a central member and two primary containment members. The central member has a top, a bottom, a resilient body with two nonlinear edges and two lateral containment members separately mounted at the two nonlinear edges of the resilient body to define a gap between each lateral containment member and the corresponding edge of the resilient body. The primary containment members are mounted respectively on the top and bottom of the central member and are attached to the lateral containment members of the central member. Accordingly, the shock-absorbing tie brace is easily manufactured and has an enhanced structural strength.
