Solution Overview
Problem
Conventional strike trainers face issues with durability and shock absorption, as metal bases are expensive and heavy, while plastic bases are prone to breaking under impact forces.
Innovation Solution
A strike trainer design featuring an attachment assembly with a metal sleeve, inner and outer stabilizers, a spring-based shock absorber, and a target mount with metal and plastic components, providing enhanced stability and shock absorption through a resilient assembly and energy distribution across multiple components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal base is used, then strength and durability are improved, but weight and cost increase
Solution Approach 1:
The base is divided into an upper base portion and a lower base portion, with the resilient body positioned between them. This segmentation allows the use of lighter materials while maintaining structural integrity through the distributed load-bearing structure.
Solution Approach 2:
The base combines metal and plastic materials in a composite structure. The upper base portion can be metal for strength, while the lower base portion can be plastic for weight reduction, creating a balanced composite structure that optimizes both strength and weight.
2Weight of moving object
If a plastic base is used, then weight and cost are reduced, but durability and shock absorption capacity deteriorate
Solution Approach 1:
A resilient body is pre-installed between the upper and lower base portions to provide shock absorption before impact occurs. This beforehand cushioning protects the plastic base and connectors from breaking under impact forces by absorbing the shock in advance.
Solution Approach 2:
The base uses a composite structure combining plastic and metal portions, where the plastic provides lightness and the metal portions (such as the metal sleeve in the attachment assembly) provide localized strength and durability at critical connection points.
3Device complexity
If a simple connector is used, then device complexity is reduced, but shock absorption capacity and durability worsen
Solution Approach 1:
The attachment assembly is segmented into multiple components including an attachment body, outer stabilizer, metal sleeve, and inner stabilizer. This segmentation distributes the impact forces across multiple elements rather than concentrating them on a single connector, enhancing strength while maintaining manageable complexity.
Solution Approach 2:
The attachment assembly combines metal and plastic components (metal sleeve with plastic attachment body) to create a composite connector structure that provides both durability and appropriate flexibility for shock absorption.
4Reliability
If a resilient body is added, then shock absorption capacity is improved, but device complexity and cost increase
Solution Approach 1:
The resilient body is merged with the base structure itself, forming an integrated unit where the resilient body becomes an inherent part of the base rather than a separate附加 component. This merging reduces overall device complexity while maintaining shock absorption capacity.
Solution Approach 2:
The resilient body serves multiple functions: it acts as a shock absorber, a structural connector, and a mounting surface for the target. This multi-functionality reduces the need for additional components, thereby reducing device complexity while improving shock absorption capacity.
