Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compaction apparatuses skip compaction cycles when storage battery charge is insufficient, leading to incomplete waste compaction and inefficiency.
Innovation Solution
Incorporation of a back-up battery that couples with the driving means and controller to ensure the waste compaction ram completes its stroke, and a locking mechanism to prevent waste insertion until the battery is sufficiently charged, along with a sliding panel to maintain compacted waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the compaction apparatus skips compaction cycles when storage battery charge is insufficient, then the battery is preserved for future use, but compaction productivity decreases and waste compaction becomes incomplete
Solution Approach 1:
The patent introduces a back-up battery as a cushioning mechanism that activates only when needed. The control system continuously monitors the storage battery charge level and triggers the back-up battery to compensate when the storage battery falls below a threshold during operation, ensuring compaction cycles are never skipped due to insufficient charge.
Solution Approach 2:
The back-up battery acts as an intermediary energy source between the storage battery and the driving means. When the storage battery charge is insufficient, the back-up battery steps in as a mediator to provide the necessary power, allowing the compaction cycle to complete without interruption or skipping.
2Use of energy by stationary object
If the compaction apparatus waits for the storage battery to be sufficiently charged before starting a compaction cycle, then energy is conserved, but compaction productivity decreases due to delayed operation
Solution Approach 1:
The back-up battery serves as a pre-prepared energy cushion that activates only when the storage battery charge drops below a predetermined threshold during operation. This ensures that compaction cycles can start immediately without waiting for the storage battery to be sufficiently charged, while still conserving energy by using the back-up battery only when necessary.
Solution Approach 2:
The control system enables continuous compaction operation by switching between the storage battery and back-up battery power sources. The useful action of waste compaction continues without interruption or delay, maintaining productivity while the storage battery conserves energy for future cycles.
3Ease of operation
If the waste insertion opening remains accessible during low battery conditions, then waste insertion is convenient, but energy is wasted by allowing operations that cannot be completed
Solution Approach 1:
The control system continuously monitors the storage battery charge level and provides feedback to the control unit. When the charge level falls below a predetermined threshold, the system automatically activates the back-up battery, ensuring that waste insertion operations can be completed without energy waste while maintaining ease of operation.

AI summary
A compaction apparatus (1) comprises: - a waste insertion pillar (5) to be placed on an underground waste container and provided with a lockable waste insertion opening (9) and a waste compaction opening (21); - a control cabinet (7) located beside the waste insertion pillar; - a waste compaction ram (25) located inside the waste insertion pillar and displaceable between a retracted position and a compaction position for a waste compaction opening (23); - a solar panel (15); - a storage battery (27) located in the control cabinet; - driving means (29) which are powered by the storage battery for displacing the waste compaction ram; - a level sensor (31) which emits a signal if the waste in the waste insertion pillar rises above a certain level; and - a controller (33). If during a compaction stroke the charging level of the storage battery drops below a preset limit value at which the waste compaction ram cannot finish the compaction stroke, the controller couples a back-up battery (35) to the driving means and it controls the driving means to take the waste compaction ram back to the retracted position.
