Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional load test apparatus are designed with separate resistance units and cooling devices, then the functional requirements are met, but the assembly and wiring processes become complicated
Solution Approach 1:
The patent combines the resistance unit and cooling device into an integrated assembly where the cooling device is positioned to directly face the resistance unit through a facing relationship. This merging reduces the number of separate components that need to be assembled and wired, thereby simplifying the assembly process while maintaining the functional independence of both components.
Solution Approach 2:
The patent divides the load test apparatus into modular components (resistance unit, cooling device, control unit) that can be independently manufactured and then assembled. The facing relationship creates a self-contained module that can be assembled as a unit, reducing overall assembly complexity.
2Power
If the load test apparatus is designed to handle large loads, then the testing capability is improved, but the space requirement increases
Solution Approach 1:
The patent utilizes the facing relationship between the cooling device and resistance unit to arrange components in three-dimensional space rather than spreading them out in a single plane. This vertical or depth-based arrangement allows the apparatus to handle large loads while maintaining a compact footprint by stacking or layering components.
Solution Approach 2:
The cooling device and resistance unit are arranged in a nested or tightly integrated configuration where the cooling device faces the resistance unit directly, allowing one component to be positioned within or adjacent to the other in a space-efficient manner that accommodates large load capabilities without proportionally increasing the apparatus footprint.
3Adaptability or versatility
If the apparatus is installed outdoors, then the versatility is improved, but the risk of dust and moisture ingress increases
Solution Approach 1:
The facing relationship between the cooling device and resistance unit creates a configuration where the components can be enclosed together in a protective housing or shell. This arrangement allows the integrated assembly to be sealed as a unit, protecting against dust and moisture ingress while maintaining the ability to install in various outdoor environments.
4Area of stationary object
If multiple components are arranged in a narrow space, then the space efficiency is improved, but the wiring complexity increases
Solution Approach 1:
By merging the resistance unit and cooling device into a facing arrangement, the patent reduces the number of separate connections needed. The integrated assembly allows for consolidated wiring harnesses and connection points, simplifying the wiring process even though the components are arranged in a compact configuration.

AI summary
A load test apparatus includes: a first resistance unit that has a plurality of first resistors and a first holding part holding the plurality of first resistors; and a first cooling part that includes a cooling device sending cooling air to the plurality of first resistors; a control part that includes a power source terminal part connected to a power source to be tested and an operation part; and a relay part that includes a switching device connected to the power source terminal part and the first resistance unit. The cooling device in the first cooling part faces one first opening in the first holding part. The first cooling part and the first resistance unit are arranged in a third direction (z direction) orthogonal to a first direction (x direction) and a second direction (y direction), and a first load test part.
