Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the battery module is positioned beneath the cab to protect it from impact, then the protection of battery elements is improved, but the ease of access for installation and maintenance deteriorates
Solution Approach 1:
The battery module is positioned beneath the cab (vertical dimension) for protection, but accessibility is achieved through lateral access from the outer side of the vehicle (transverse dimension). This multi-dimensional positioning resolves the contradiction by allowing both protection and ease of access.
2Duration of action of moving object
If a significant volume of battery elements is carried to ensure adequate battery life, then the duration of action is improved, but the device complexity and space requirements worsen
Solution Approach 1:
The battery module serves multiple functions: it provides the necessary capacity for adequate battery life, integrates the fastening structure for simplified positioning, and enables lateral accessibility for easy installation and maintenance. This multi-functional design reduces overall system complexity.
Solution Approach 2:
The fastening structure is integrated directly into the battery module, combining the battery elements and mounting mechanism into a single unified component. This eliminates the need for separate positioning solutions and reduces device complexity.
3Ease of operation
If the battery module is made easily accessible from the outer side for simple installation and maintenance, then the ease of operation is improved, but the protection from impact deteriorates
Solution Approach 1:
The battery module is positioned beneath the cab (vertical dimension) for protection, but accessibility is achieved through lateral access from the outer side of the vehicle (transverse dimension). This multi-dimensional positioning resolves the contradiction by allowing both protection and ease of access.
